Magnification on a boat is a trap. Every degree of deck roll that a 7x pair shrugs off gets multiplied tenfold at 10x, so the image you want at range turns into shaking pixels you cannot read. That is why image stabilized binoculars for boating exist as a category at all, and why skippers who switch to them usually never go back to a plain 7×50.
We spent months putting these eight stabilized pairs through real comparison work, reading the owner feedback closely and cross-checking every spec against the manufacturer listing. The short version: if you regularly look past 200 yards from a moving vessel, stabilization is worth the money and the batteries. If you mostly cruise close to shore in flat water, a good conventional marine binocular does the same job for a fraction of the setup.
Here is the fast answer before the detail. The Canon 18×50 IS All-Weather is our overall pick for sheer identification power off the bow. The Canon 10×42 L IS WP is the sealed all-day pair. The Fujinon Techno-Stabi 14×40 is the one most experienced mariners name first. Smaller craft should look at the Nikon Stabilized 12×25, which weighs under a pound.
We also wrote about lighter glass for shore-based use in our guides to the best binoculars for stargazing and the best binoculars for bird watching beginners, since magnification and glass choices carry over between those uses.

1. Canon 18×50 IS All-Weather — Best for Long-Range Identification
Canon 18×50 Image Stabilization All-Weather Binoculars
18x/50mm optical IS
7.5 degree field of view
4.1 lb
2 AA batteries
Pros
- Steadies the view at 18x where plain optics fail
- Bright 50mm objective for scanning water
- All-weather shock and water resistant build
- Large centre focus knob works one-handed
Cons
- Heavy at 4.1 lb for long handheld sessions
- Fixed focus limits close-range versatility
- Bulky porro prism body
This is the pair we would hand a skipper whose job is telling a 200-yard-away dolphin from a 300-yard-away one. Eighteen times magnification is well past the point where conventional marine binoculars stop working, and the built-in optical stabilization is what makes that number usable rather than decorative.
Owner feedback is unusually consistent about why it works. Reviewers repeatedly single out the stabilization for scanning distant water and shorelines, and the 50mm objective is described as bright with a wide field for its power. The 7.5 degree true field is narrow, as it must be at 18x, but the stabilisation does the work of holding a target in the middle of it long enough to identify.
The 15mm eye relief and large centre focus knob make it comfortable in daylight and simple to operate with wet hands. Because it is water and shock resistant with a rubber exterior over an aluminium and polycarbonate body, it takes the rigour of a working deck better than the price suggests.
The honest drawback is mass. At 4.1 pounds this is the heaviest stabilized binocular in our group, and reviewers describe the body as large in the hand and tiring over long sessions. If you are on a tower for six hours with a harness and a fixed mount, that is fine. If you are raising it from a helm chair on a center console all morning, it will make your arms feel it.
What you gain with the 18×50
Identification power at distance is the whole point. Marker numbers, hull colours, distant traffic and large pelagic species become readable rather than suggestive.
The wide 50mm objective also keeps the view bright enough to use well before dawn and after sunset, which is when a lot of the best offshore sighting happens.
Where it falls short
Fixed-focus design with individual focus means close work is limited, so this is a spotting instrument rather than a general-purpose pair.
The porro prism body is bulky, and 4.1 pounds is a real consideration if you already have a full deck of gear to carry.
2. Canon 10×42 L IS WP — Best for All-Weather, All-Day Use
Canon 10×42 L is WP Image Stabilized Binoculars
10x/42mm optical IS
16mm eye relief
Waterproof and fogproof
2.4 lb
Pros
- Full waterproof and fogproof sealing for wet decks
- Stabilization steadies the view at 10x
- 16mm eye relief suits long watches
- Ultralow-dispersion glass stays bright and clear
Cons
- Battery power required for stabilization
- Accessory kit adds bulk
- 4.2mm exit pupil is modest for pre-dawn use
If your boat lives in the rain and you want one pair that never worries you, this is the safest buy in the list. It is the only model here rated simply waterproof and fogproof rather than water resistant, and that distinction matters when spray comes over the bow for four hours.
Ten times magnification with a vari-angle prism stabilizer is a sensible balance for most working boats. Reviewers highlight the combination of waterproofing and stabilization as the key benefit, with strong marks for optical clarity and eye comfort. Ultralow-dispersion lead-free glass elements and full Super Spectra multi-layer coatings handle the low contrast of a hazy horizon better than ordinary glass.
The 16mm eye relief is the longest of the three Canons here, and that is why it is our pick for long observation sessions. A central focus design with a large knob means you can find focus with one hand while the other holds a rail or a helm wheel.
At 2.4 pounds it is roughly half the weight of the 18×50, so it is much easier to keep on a neck strap for a full day. The criticism owners raise most often is not the optics but the kit: the padded case, strap and rainguard add bulk to a stowage locker that is already cramped.
Why the sealing rating decides it
Waterproof and fogproof sealing means you can leave it in a wet cockpit without checking the weather first. Sealed nitrogen-purged housings are what stop internal fogging when you move from a chilled deck into a warm cabin.
Two AA alkaline cells power the stabilizer, so a spare set fits in a shirt pocket and there is no proprietary pack to worry about on a week-long trip.
Where it falls short
At 10x it will not resolve a distant hull number the way the 18×50 or the Fujinon 14×40 does. It is the better all-rounder, not the better spotter.
A 4.2mm exit pupil is fine in daylight but means the image goes soft sooner at dusk than a 50mm objective would.
3. Canon 15×50 IS — Best Value Stabilized Pair for a Working Boat
Canon 4625A002 15×50 is Image Stabilized Binocular
15x/50mm optical IS
67.5 degree apparent field
2.6 lb
2 year warranty
Pros
- Stabilizer makes 15x usable handheld
- Bright 50mm objective for scanning water
- Weatherproof slip-resistant armor for wet decks
- Large centre focus knob for quick adjustment
Cons
- Water resistant rather than waterproof sealed
- 15mm eye relief tires on long sessions
- Lowest average rating of the Canon IS models
This is the middle of the Canon stabilized line and, on the balance of spec, the strongest argument for value in the entire list. Fifteen times power with an optical stabilizer puts you in the range band most anglers actually need, at 2.6 pounds rather than four.
Owners value exactly the combination you would hope for: high magnification that is genuinely usable handheld, plus a bright 50mm objective for scanning water. The optical stabilizer compensates for handshaking and minute vibration at the press of a button, which on a heaving deck is the difference between seeing a bird and guessing at one.
Weatherproof slip-resistant armor is the right call for a wet deck, and the large centre focusing knob allows fast, precise corrections. The 67.5 degree apparent field of view is the widest of the three Canons, which makes scanning for traffic less of a hunt.
The trade-off is sealing. This model is water resistant rather than fully waterproof and fogproof, so it is a poorer choice for a boat that takes spray routinely. Reviewers also find the 15mm eye relief tiring over long sessions, and the 4.3 average is the lowest of the Canon stabilized group.
When this is the right pick
Most trips are still water, moderate spray and daylight hours. In that environment the sealing difference between this and the 10×42 matters far less than the extra power.
The 50mm objective also handles dusk better than the smaller stabilized models here, which matters for pre-dawn and post-sundown runs.
When to step up instead
If you boat offshore or in a place with persistent spray, move to the waterproof 10×42 L IS WP. Sealing failures are cheap to prevent and expensive to discover.
At 3.3mm the exit pupil will not carry you through full darkness. That is a job for night optics, not for any of the stabilized daylight pairs.
4. Fujinon Techno-Stabi TS1440 14×40 — Most Versatile for Marine Use
Fujinon Techno Stabi TS1440-14×40 Image Stabilization Binocular
14x/40mm gimbal stabilization
5 degrees correction
Waterproof and fogproof
4 AA cells
Pros
- Owners rate the 5 degrees of correction above Canon systems
- Rock-steady image on a moving or rolling boat
- Waterproof and fogproof sealing praised by sailors and anglers
- Two-button activation with no learning curve
Cons
- Bulky and heavy body compared with other stabilized models
- Fixed frame does not adjust for different eye spacing
- 40mm objective is dimmer at dusk
- Objective lens caps not included
This is the binocular most experienced mariners name when you ask them directly, and the owner feedback explains why. Marine users and birders repeatedly describe the stabilization as transformative, calling the image rock solid even on a moving or rolling boat, and several reviewers rank it above the Canon IS line for correction range.
Five degrees of optical stabilization correction is more correction power than anything else in this group. The mechanism sits on a mechanical gimbal rather than a powered vari-angle prism, which means the view still works with the batteries removed — a meaningful safety margin on a long trip.
Fourteen times power plus stabilization lets users spot markers, boats and whales that a 7×50 marine pair simply cannot resolve. The waterproof and fogproof sealing is explicitly praised by sailors and anglers, and a fiberglass-reinforced body with rubber armor gives a firm non-slip grip in spray.
The complaints are all about size. Reviewers compare the body to military equipment, which tells you what you are carrying up the ladder. The frame is fixed and does not adjust to different eye spacing, and objective lens caps are not included in the package.
Why the gimbal design matters at sea
Because a gimbal holds the light path steady mechanically, the binocular degrades gracefully. If a cell dies mid-watch the picture is still there, just shakier.
Simple two-button activation with no menu means there is nothing to fumble with one-handed in a following sea.
Where it falls short
The 40mm objective produces a 2.86mm exit pupil, which is dimmer at dusk than the 50mm objectives on the Canon models. It is not a pre-dawn instrument.
Weight and bulk are the standing complaints, and the non-adjustable frame means one size does not fit every face.
5. SIG SAUER Zulu6 HDX OIS 16×42 — Best for Long-Range ID in a Compact Body
SIG SAUER Zulu6 FDE HDX OIS 16X42mm Roof Prism Binocular
16x/42mm OIS
Scan and Target modes
IPX-7 rated
1.02 kg
Pros
- Exceptionally compact and light for a 16x stabilized pair
- Target Mode adds up to 50 percent more stabilization
- OIS removes hand jitter so distant targets are identifiable
- IPX-7 waterproofing suits wet conditions
Cons
- Focus wheel has noticeable slop
- One reviewer reports severe veiling glare and flare
- Narrow tunnel-like field of view complicates target acquisition
- Weaker in low light than the spec suggests
- Objective caps not included
Sixteen times magnification inside an aluminium roof-prism body weighing just over a kilogram is genuinely unusual. Owners repeatedly make the same comparison: they prefer this pair to far larger premium glass because of the size and weight for the correction on offer.
The two-mode system is the interesting part. Scan Mode runs continuous correction for sweeping a horizon, and Target Mode increases stabilization by up to 50 percent for locking onto one distant object. That switch is the reason the OIS can make a distant target countably identifiable rather than merely visible.
HDX glass lenses are specified for light transmission, resolution and definition, and the IPX-7 rating means immersion protection for spray and sudden downpours. It is also tripod mount compatible, so a tower or rail installation is straightforward.
Buyer feedback is honest about the trade-offs. Several owners report a focus wheel with noticeable slop, one reports severe veiling glare and flare, and a narrow tunnel-like field of view makes target acquisition the harder part of the job. Low-light performance is also called weaker than the specification suggests.
Why the mode switch matters
Scan Mode is a broad, gentle correction suited to a moving search pattern. Target Mode trades a little steadiness of framing for correction power when you are holding one object.
Having both means one pair covers scanning and ID without you carrying a second optic.
Where it falls short
The listed field of view of 164 feet is narrow, and reviewers describe it as tunnel-like. Finding a bird in a spread first is the hard part.
With a 2.63mm exit pupil it is a daylight instrument. Pre-dawn work calls for something else.
6. Nikon Stabilized 12×25 — Best for Sea Kayaks and Small Craft
Nikon STABILIZED 12×25 Binoculars – Optical Image Stabilization, Blur-Free View, Waterproof Design, 12x Magnification for Hunting, Birdwatching & Outdoor Activities
12x/25mm electronic IS
13.9 oz
Up to 12 hours on AA
Waterproof
Pros
- Rock-solid stabilization that makes 12x easy to hold and follow
- Very light at 13.9 oz and pocketable
- Sharp colour-accurate optics from multicoated lenses
- Folding hinge adjusts to different eye spacing
Cons
- 25mm objective is unsuited to low light or dusk
- Included pouch is low quality
- No rear lens cap and the front protector fouls the diopter
- Short listed eye relief of 2.1mm
Everything else in this list weighs between 1.6 and 4.1 pounds. This one weighs 13.9 ounces, which changes the calculation entirely for anyone in a sea kayak, a small tender or a centre console where stowage is measured in litres.
Owners rate the stabilization and optical clarity very highly and treat the pair as a lightweight, travel-ready alternative to bulkier stabilized binoculars. The electronic system compensates for natural hand movement, and at 12x it makes following a moving subject realistic rather than exhausting.
The power management is genuinely good for boating. It runs up to 12 hours on standard AA batteries and shuts down automatically after 60 minutes of inactivity, so a cell left on overnight does not drain the set before a pre-dawn start.
The waterproof aluminium housing, multicoated lenses with high-reflectivity silver alloy prism coatings, and a textured slip-resistant focus wheel all fit the marine brief. It mounts to a standard 1/4-20 tripod adapter and carries a limited lifetime manufacturer warranty.
Why weight changes the decision
Hand fatigue is a real cost on a long day, and owners of heavier stabilized models call it out repeatedly. At under a pound you can raise these for an entire watch without switching hands.
The folding centre hinge adjusts to different eye spacing, which matters if you share a boat with someone else.
Where it falls short
A 25mm objective with a 2.1mm exit pupil is a daylight optic. Reviewers are blunt that it is not suited to dusk or low light, and that is the biggest gap against the 50mm Canon models.
The accessory package disappoints: a cheap pouch, no rear lens cap, and a front protector that interferes with the diopter adjustment.
7. Kite Optics APC Stabilized 16×42 — Best for Wide Scanning at Long Range
Kite Optics APC Stabilized 16×42 Binoculars – Wide-Angle Stabilized Binoculars for Hunting, Bird Watching, and Long-Range – 16x Magnification, Waterproof, Built for The Outdoors
16x/42mm stabilization
2 and 3 degree correction
IPX7 nitrogen filled
1.6 lb
Pros
- Highest average rating in the group with no ratings below 4 stars
- 2 and 3 degree correction holds steady in wind and on moving vessels
- IPX7 waterproof and nitrogen filled for marine conditions
- 16x magnification with a 42mm objective gives sharp long-range detail
Cons
- Small sample of 21 reviews from the initial production run
- Autofocus behaviour not described in owner feedback
- Metal housing keeps weight above ultralight models
This one carries the highest average rating of anything we reviewed, with no ratings below four stars. Owners report consistently strong stabilization performance in dynamic, windy and marine conditions, and clear, bright images from the 42mm roof prism.
What stands out for a boat is the combination of sealing and correction. It is IPX7 rated and submersible to 1 meter for 30 minutes, nitrogen gas filled against internal fogging in changing weather, and specified for land, sea and air observation including boats.
The two selectable correction angles, 2 degree and 3 degree, let you tune the amount of stabilization to the motion. That is more control than most stabilized marine binoculars give you, and it is the reason the picture holds steady in wind and from a moving vessel.
Be aware of what you are buying. The review base is 21 ratings, all from the initial production run, which means long-term durability is not yet documented the way it is for the Canon and Fujinon models. Autofocus is listed but owners do not describe how it behaves, so treat it as unproven rather than as a feature to rely on.
What you gain here
A 56 degree apparent field of view at 16x is unusually wide for stabilized glass, and wide fields are what experienced mariners actually ask for when scanning for traffic and bait.
At 1.6 pounds it is also lighter than the Canon 18×50 by more than half a kilo while offering similar power.
Where caution is due
Twenty-one reviews is a thin base. A model rated highly on a small sample is a different proposition from one with hundreds of owners reporting years of saltwater use.
If you keep optics long-term and want a documented repair history, the Canon and Fujinon lines carry more field evidence.
8. Kite Optics APC Stabilized 12×42 — Best for Long Observation Sessions
Kite Optics APC Stabilized 12×42 Binoculars – High-Performance Binoculars for Bird Watching, Hunting, Marine Use – 12x Magnification, Image Stabilization, Waterproof, Clear Views
12x/42mm stabilization
17mm eye relief
IPX7 nitrogen filled
1.6 lb
Pros
- Military-grade stabilization steadies the view in wind and from moving boats
- IPX7 waterproof and nitrogen filled against rain humidity and spray
- 17mm eye relief supports comfortable extended sessions
- 3.5mm exit pupil gives a brighter image for its class
- Stabilization reduces hand tremor and eye fatigue over long watches
Cons
- Small review base of 15 ratings
- Manual individual focus rather than a centre focus wheel
This is the comfort pick. The 17mm eye relief is the longest in our group, and that single number is why owners report being able to stay on the glasses through long observation sessions instead of rubbing tired eyes.
The stabilization is specified for viewing in wind and from moving boats, vehicles and aircraft, and owners rate the combination of stabilization and all-weather sealing very highly. They highlight reduced eye fatigue and steady viewing on moving platforms as the practical benefits.
Light gathering is the other strength. A 3.5mm exit pupil is the second brightest in this list after the Canon 10×42, so the image holds up better than its size suggests when the light starts to go.
Sealing matches the 16×42 sibling: IPX7 rated, submersible to 1 meter for 30 minutes, and nitrogen filled to prevent internal fogging across temperature changes. Tripod mount compatibility is included for tower or rail mounting.
The limitations are straightforward. Fifteen ratings is a small review history, so long-term durability is less well documented than for the Canon and Fujinon models. And it uses manual individual focus rather than a centre focus wheel, which is slower to adjust with one hand while you are holding on to a rail.
Why eye relief matters on a boat
Long watches are the normal case for a spotter. Wider eye relief means the eyecup sits further from the eye, which reduces the pressure and smudging that build up over hours.
Reviewers also credit the stabilization with reducing hand tremor and eye fatigue over long watches, which compounds the comfort benefit.
Where it falls short
Individual focus takes practice, and it slows you down when something is moving fast and you only have one hand free.
The 43.4 degree apparent field is the narrowest here. That is a real cost on a boat where hull traffic appears at the edge of the scan.
Best Stabilized Binoculars by Boat Type
Matching the optic to the craft matters more than matching it to the budget. Here is how the eight split across the boats people actually use them on.
Sea kayak
The Nikon Stabilized 12×25 wins on weight alone at 13.9 ounces. Everything else in this list is awkward to hold in a kayak, and in a small craft your own body movement is part of what stabilization has to cancel.
Center console
For a single-helm console with wet hands and limited stowage, the Canon 10×42 L IS WP is the balanced answer: waterproof and fogproof, 2.4 pounds, central focus for one-handed operation, and enough power to check distant traffic.
Sailboat
Sailing boats combine heaving motion with spray, which favours the fully sealed options. The Fujinon Techno-Stabi 14×40 is the traditional choice among offshore sailors for its 5 degrees of correction, and its gimbal design keeps working without batteries.
Sportfishing boat
For spotting bait balls and working birds at range, the Canon 18×50 IS All-Weather has the identification power, and the SIG SAUER Zulu6 16×42 offers the same power class in a body roughly a kilo lighter with a selectable Target Mode.
Flybridge and tower
At height, vibration from the structure replaces deck roll as the problem, and stabilization has more to correct. The Kite Optics APC 16×42 with 2 and 3 degree correction settings and tripod mount compatibility suits a fixed mount, as does the SIG SAUER Zulu6.
Marine vs General-Purpose Binoculars: What to Check Before You Buy
The difference between marine binoculars and general-purpose binoculars is not mainly optical. It is the sealing, the armoring and the coatings, and you can check all three from a listing.
Sealing rating — a waterproof and fogproof rating is what survives a cockpit. Water resistant alone, as on two of the Canon models here, means keeping the rain off it.
Nitrogen purge — a nitrogen-filled housing is what stops internal fogging when you move between a cold deck and a warm cabin, or in humid tropical air.
Rubber armor — slip-resistant armor and a non-slip grip are what keep the optic in your hand when it is wet and the boat is moving.
Floating body — none of the stabilized pairs in this group float, so treat a lanyard or floating retrieval line as standard kit rather than optional.
Exit pupil — the light that reaches your eye per magnification step. The 3.3mm and 4.2mm figures on the 50mm and 42mm Canon models serve dawn and dusk far better than the 2.1mm on the Nikon 12×25.
Coatings — multicoated lenses and phase or Spectra coatings are what keep contrast and colour fidelity when you are looking into glare off water.
When You Do Not Need Image Stabilization
Honest guidance cuts both ways, and the most common forum argument about this category is that a good 7×50 is enough for most people. That is often correct.
Magnification above 7x without stabilization is what becomes unusable in a sea state, which is the entire case for spending more. If your furthest routine look is under 200 yards, or your boating happens in sheltered water, the conventional marine pair handles it and you keep the money and the weight.
Field of view width is the other reason people skip stabilized optics, and it is a legitimate one. Higher magnification always means a narrower view, and a narrow view makes it harder to find a target and to track hull traffic. If you scan constantly and spot rarely, a wide conventional view suits you better.
Finally, none of these pairs is a night-vision instrument. Once the light goes, stabilization does not help much; a thermal scope or a light-amplification optic is a different purchase for a different job.
How to Rinse and Store Stabilized Binoculars After Saltwater Use
Stabilized binoculars carry more electronics than a conventional pair, so a proper rinse routine matters more, not less. Salt crystallises inside mechanisms and attacks coatings, and a damp housing left sealed invites fogging.
Rinse with fresh water immediately. Hold the objective under a gentle stream of fresh water after every trip on salt water, and pay attention to the focus wheel and any seals.
Loosen the focus and diopter controls. Work the focus wheel and diopter through their range under running water so grit does not stay trapped in the mechanism.
Shake and drain, then air dry. Let them dry with the eyecups down and away from direct heat, which includes a cabin heater or a hot console.
Store with lenses capped, desiccant nearby. Keep them in the supplied case in a locker with a dry agent, and carry spare alkaline cells in a separate sealed pouch.
Owners of older Fujinon Techno-Stabi units report decades-old examples still working, which is the durability benchmark this category is measured against. That reputation only survives if the salt comes off promptly.
Frequently Asked Questions
What binoculars for sailing?
For sailboats, prioritise waterproof and fogproof sealing with nitrogen purge rather than raw magnification. Offshore sailors most often name the Fujinon Techno-Stabi 14×40 as their go-to stabilized marine binocular, and its mechanical gimbal keeps the view working even if the batteries die. Coastal and coastal-cruising sailors can save weight and space with a lighter stabilized pair such as the Nikon 12×25.
What is image stabilization in binoculars?
Image stabilization uses a sensor, gyro or gimbal to detect hand and boat movement and automatically shifts the internal optical elements to cancel it. The result is a view that stays steady instead of bouncing, which matters on a boat because magnification multiplies every degree of deck roll. Three commercial mechanisms exist: vari-angle prism electronic IS, a gimbal-mounted erecting prism, and digital optical image stabilization.
What are the best marine binoculars with image stabilization?
The leading options in our testing are the Canon 18×50 IS All-Weather for long-range identification, the Canon 10×42 L IS WP for fully sealed all-weather use, and the Fujinon Techno-Stabi TS1440 14×40 for the strongest stabilization correction at 5 degrees. For smaller craft the Nikon Stabilized 12×25 wins on weight, and the Kite Optics APC 16×42 offers a wide field at 16x with selectable correction angles.
Are image stabilizing binoculars worth it?
Yes if you regularly look past 200 yards from a moving boat in any real sea state, because magnification multiplies vibration and unstabilized optics above 7x become hard to use. No if your work stays close to the boat or your boating happens in sheltered water, where a good conventional 7×50 marine binocular does the same job at a fraction of the weight and cost.
What are the key differences between marine binoculars and regular binoculars?
Marine binoculars are built around sealing, armoring and coatings rather than glass alone. Look for a waterproof and fogproof rating rather than water resistant, a nitrogen-purged housing against internal fogging, and slip-resistant rubber armor for wet-handled decks. Coatings such as phase coating, SpectraCoat or multicoating also matter more over water because of glare.
Do stabilized binoculars work in rough seas?
Yes, and that is exactly the situation they were designed for. Correction ratings range from 2 and 3 degrees on the Kite Optics APC models to 5 degrees on the Fujinon Techno-Stabi TS1440. In practice the correction system absorbs deck roll and engine vibration so a magnified target stays identifiable, though no stabilized pair is useful in darkness without a thermal or night-vision optic.
Conclusion: Our Verdict for 2026
The Canon 18×50 IS All-Weather is our pick of the best image stabilized binoculars for boating in 2026, because 18 times magnification with working optical stabilization is the combination that actually changes what you can identify off the bow, and its 346 owner ratings give us the deepest evidence base on the list.
If your boat takes constant spray, take the sealed Canon 10×42 L IS WP instead. If correction power matters more than weight, the Fujinon Techno-Stabi 14×40 is the one experienced mariners keep naming. Check the current price on any of them before you commit, and rinse them in fresh water the moment you are back alongside.
