A jacket that keeps you dry ashore may perform very differently after an hour of rain and spray at the helm. For boating, keeping water out is only part of the job. You also need to move freely, see properly with the hood up and wear the jacket comfortably with a lifejacket.
For most leisure motorboating around the Solent and South Coast, an inshore or coastal jacket will provide enough protection. The right choice depends on the boat, the season and how exposed you are likely to be.
Look beyond the waterproof rating
A high waterproof rating can be useful, but it doesn’t tell you everything about how a jacket will perform on the boat.
Water can enter around seams, cuffs, collars and zips. Look for taped seams, secure wrist adjustments, a protective front closure and a hood that stays in place without restricting your view.
Breathability matters too. Handling lines, moving fenders and working around the boat can quickly make you warm, even in poor weather. A jacket that keeps rain out but traps too much moisture inside can still leave you uncomfortable.
Inshore or coastal jacket?
For many UK leisure boaters, an inshore jacket provides enough protection for day trips and relatively sheltered coastal boating.
These jackets tend to be lighter and easier to move in while still providing protection from rain, wind and occasional spray. They also leave room for layers underneath as temperatures change.
A coastal jacket becomes more useful when you expect longer periods outside, regular spray or less opportunity to get out of deteriorating weather. Higher collars, more substantial cuffs and greater hood protection can make a noticeable difference.
Offshore jackets provide greater protection for sustained exposure but are usually heavier and bulkier. For somebody mainly making short leisure trips around the Solent, that additional protection may not be necessary.
Make sure the hood works at the helm
Put the hood up and turn your head fully in both directions. You should still be able to see around you without the hood falling across your eyes or forcing you to turn your whole upper body.
A peaked hood can help keep rain away from your face, while adjustment around the head and face helps prevent it blowing backwards in stronger wind.
At the helm, you still need a clear view of other vessels, navigation marks and what your crew are doing.
Check the fit with your usual layers
Try the jacket with the clothing you are likely to wear underneath it rather than over a T-shirt in a warm shop.
There should be enough room for a base layer and fleece or lightweight insulated layer without restricting movement. Raise your arms, reach forwards and sit down as though you were at the helm.
Sleeves should provide enough coverage without interfering with controls or line handling. The jacket should also remain comfortable when sitting for longer periods.
Wear it with your lifejacket
Try the jacket and lifejacket together before relying on the combination afloat.
The lifejacket needs to sit correctly over your clothing without the jacket collar pushing it into an awkward position. You should still be able to reach its adjustment points and any equipment you normally carry.
This is particularly important when adding thicker winter layers. Extra clothing should not make the lifejacket excessively tight or interfere with its correct fit.
Think about the boating you actually do
A motorboat with a sheltered wheelhouse creates very different clothing requirements from an open RIB where everyone aboard may be exposed to wind and spray.
Consider how long you normally spend outside, whether you boat throughout winter, how exposed the helm is and the type of passages you make.
The weather forecast will also influence what you wear and carry. A dry morning can develop into a much colder and wetter afternoon, particularly once wind chill and spray are added.
Which features are worth having?
A secure adjustable hood, well-sealed cuffs, taped seams and a collar that protects your neck without restricting movement are more useful than a long list of minor features.
Pockets should be accessible while wearing a lifejacket, although phones and other items that must stay dry are better protected separately.
Bright or reflective detailing can also make you easier to see in poor light.
Look after the waterproofing
Salt and dirt can gradually affect waterproof clothing, particularly around cuffs, zips and collars.
Rinse salt away where appropriate and allow the jacket to dry properly before storing it. Follow the manufacturer’s washing instructions, as ordinary detergent or fabric conditioner may not be suitable for technical fabrics.
If water stops beading on the outer fabric, the water-repellent finish may need restoring. Damaged seams, zips or fabric need repairing separately.
Choose protection that suits your boating
For many leisure boaters around the Solent and South Coast, a good inshore or coastal jacket will be more practical than heavy offshore clothing.
How exposed you are, how long you spend outside and the conditions you normally boat in matter more than buying the jacket with the longest specification.
On longer trips, waterproof clothing also forms part of the equipment and preparation needed for a coastal passage. Whatever jacket you choose, it should keep the weather out without restricting movement, visibility or the fit of your lifejacket.
FAQs about waterproof jackets for boating
Do you need waterproof trousers as well as a boating jacket?
Waterproof trousers can be useful when spray, prolonged rain or an exposed helm is likely to leave your lower body wet. They are particularly worth considering on open boats or longer trips where getting changed easily may not be possible.
Does a waterproof jacket need to be specifically designed for boating?
Not necessarily for every trip. What matters is whether the jacket provides suitable protection, freedom of movement and visibility for the conditions you expect. Marine-specific designs may include features intended for spray and exposed conditions, but the level of protection should match the boating you actually do.
Is a smock or a full-zip jacket better for motorboating?
A full-zip jacket is often easier to put on, remove and ventilate during changing conditions, while a smock can provide fewer openings for water to enter. The better choice depends on personal preference, how exposed you are and how frequently you expect to add or remove the outer layer.
Can a waterproof jacket replace warm clothing underneath?
No. A waterproof outer layer is mainly there to protect against wind and water. In colder conditions, separate insulating layers are still needed underneath so that you can adjust warmth without relying on one bulky garment.
Should you carry a spare waterproof layer on longer trips?
It can be sensible where the passage is longer or conditions are uncertain. A spare dry layer gives you another option if clothing becomes damaged or wet and can also be useful for a passenger who arrived without adequate protection.
