What to Wear on a Boat Trip: A Plain Guide for UK Waters
For a boat trip in the UK, wear layers you can add and take off: a cotton tee, a brushed cotton flannel shirt, a wool jumper or gilet, and a waterproof shell carried in your bag. Add a cap with an adjustable strap, sunglasses, and flat shoes with soft, grippy soles. It is nearly always colder on the water than on the quay, so pack one more layer than the forecast suggests.
That holds for a ferry to the islands, a wildlife trip out of a harbour town, a morning on a mate's boat or an evening on a loch. This is the plain version: what to wear, what to leave at home, and why the old fisherman's answer, a wool jumper worn over a cotton shirt, still works.
Why Does It Feel Colder on the Water?
It feels colder on the water because a moving boat makes its own wind, there is nothing on deck to shelter behind, and spray wets whatever you have on. Even on a still day, the air moving across the deck strips warmth from you faster than the same temperature on land. There is no hedge, wall or tree to stand behind, and spray finds its way into every gap. Light bounces off the water as well, so you can be cold and sunburnt on the same trip.
The answer is not more kit. It is a few warm layers that go on and come off in seconds, with a shell on top for the days that need one. Before you go, check the Met Office inshore waters forecast for your stretch of coast and dress for the wind it gives, not the temperature on the beach.
What to Wear on a Boat Trip: The Clothing List
- Base layer: a plain cotton tee.
- Shirt: a brushed cotton flannel, worn open or buttoned up.
- Warm layer: a wool jumper, a wool gilet, or both.
- Outer layer: your own packable waterproof, in the bag until the weather means it.
- Head: a cap with an adjustable back for sun and glare, and a warm hat from October to March.
- Feet: flat shoes with soft rubber soles, plus warm socks.
- Extras: sunglasses on a cord, gloves in the colder months, and a small bag that can get wet.
Ferry, Wildlife Trip, Day Boat or Loch
Ferry
On most crossings you can sit inside, and the open deck is where the view is. Dress for the lounge and carry the layer for the deck: a flannel over a tee, with the jumper or gilet in a bag you can reach without unpacking it.
Wildlife trip
A wildlife boat spends long stretches with the engine off while everyone waits and watches. Standing still in a breeze is colder than moving, so this is the trip for a jumper and a gilet together, gloves from autumn onwards, and a cap that keeps the glare out of the binoculars.
Day boat
On a friend's boat you may be asked to help, so keep the arms free: tee, flannel and gilet, with nothing loose that could catch on a cleat or a line. Ask about soles before you board and wear the lifejacket you are handed.
Loch
Fresh water is still cold water, and many lochs sit between hills that send the wind down their length. Dress as you would for the sea. From late spring to early autumn in Scotland, carry midge repellent and keep the flannel buttoned to the cuff on the shore and the pontoon.
The Shirt: Brushed Cotton Flannel
A flannel shirt is the layer you wear from the car park to the end of the day. It is warm in the breeze, open at the collar when the sun comes out, and it sits cleanly under a jumper or a gilet.
The Brae Flannel Shirt was built for the riverbank and the boat. It is 100% cotton, brushed on both sides, with a hidden button-down collar that keeps the points still in the wind and a microfibre lens cloth sewn under the hem for salt on your sunglasses. The Munro Flannel Shirt is the plain version in the same regular fit, with two deep chest pockets under buttoned flaps that keep small things where you put them. Both are £95, and the rest of the colours are in the flannel range.
The Jumper: A Fisherman's Rib
Fishermen wore heavy knitted jumpers on the water for generations, and the reasons have not changed. A dense knit holds warmth around the body in a cold breeze and keeps it while the boat is moving.
The Tarbert Fisherman's Jumper is a proper heavyweight in a 5 gauge traditional fisherman's rib. Raglan sleeves give easy movement for hauling a line or reaching for a rail, and the rolled collar is cut with room for a shirt collar underneath, so it goes straight over a flannel. It is £115, in Slate.
The Warm Layer: Gilet or Jacket
On a boat your arms are busy: holding on, passing things across, handling a rope or a rod. A wool gilet keeps your core warm and leaves your arms free. The Torr Wool Gilet is cut in our own Tech Wool, with a chest pocket and two deep waist pockets on YKK Vislon zips, which matters when your phone and keys are a long way above the water. It is £185.
When it is colder, the Arkle Wool Jacket sits over a flannel or a jumper and has a brushed cotton inner neck, so nothing sits cold against the skin. The waist pockets zip shut, and two open inside pockets take a folded map or a ticket. It is £240. On the wettest days it sits under a shell. The rest of the time it is the jacket.
Tech Wool is not waterproof, and we do not sell it as one. If spray is coming over the bow or rain is forecast, put your own waterproof shell on top and keep the wool underneath for warmth.
The Cap: Glare and Wind
Glare off the water is harder on the eyes than glare on land. A peaked cap cuts it, and an adjustable back means you can set it tight enough to stay on when the boat picks up speed. The Rollock Canvas Cap has a brass buckle at the back and canvas that stands up to sun bleaching. The Tarvie Cap in Shoreline Blue is the other choice, in a blue that suits the coast. Both are £25, and the rest are in headwear.
Trousers and Shoes
Trousers get less thought than the top half and matter as much. Spray lands on your legs first when you sit near the rail, and wet denim stays wet. Wear trousers that dry in the breeze, such as cotton twill, cords or walking trousers, and keep the jeans for the drive home. On a wildlife trip you may sit still for hours, so a warmer trouser in autumn and winter makes more difference than a thicker coat.
Shoes need a flat, soft rubber sole. Decks, pontoons and ferry ramps are wet more often than dry, and a leather sole slides on all three. Deck shoes, trainers or light walking shoes all work. Put a spare pair of warm socks in the bag, because feet are often the first thing to get cold on the water.
What Not to Wear on a Boat
- Heels and leather soles. Wet decks and pontoons are slippery. Flat rubber soles grip.
- Flip flops and sandals. They slide on a wet deck, and your feet stay cold once the spray starts.
- Black soled shoes on someone else's yacht. Many owners ask for non-marking soles. Ask before you board.
- One thick coat and nothing under it. You cannot adjust it, and a lifejacket fits badly over a bulky coat.
- A hat with no strap or adjuster. It will end up in the water.
- Heavy denim on a wet trip. Once soaked by spray it stays cold and heavy for the rest of the day.
Whatever you wear, wear the lifejacket or buoyancy aid your skipper gives you, over the top of your layers.
What to Wear on a Boat Trip, Season by Season
Spring boat trip
Tee, flannel and a wool gilet. The air is colder than the light suggests, especially on the way out.
Summer boat trip
Tee and a flannel worn open, a cap and sunglasses. Keep a jumper in the bag for the trip home, when the wind has picked up and the sun has dropped.
Autumn boat trip
Flannel, a fisherman's jumper, and a shell in the bag. Add the Arkle for evening trips.
Winter boat trip
Tee, flannel, jumper, and a gilet or jacket, with your own waterproof shell on top, a warm hat, gloves and warm socks. Short trips feel long in December.
Common Questions
What should I wear on a boat trip in the UK?
For a boat trip in the UK, wear a cotton tee, a brushed cotton flannel shirt and a wool jumper or gilet, with a waterproof shell in your bag. Add a cap, sunglasses and flat shoes with grippy rubber soles. Pack one more layer than you think you need, because it is colder on the water than on land.
Do I need a waterproof for a boat trip?
Yes, carry a packable waterproof shell on any UK boat trip, even in summer. Spray and showers can arrive with little warning. Wear warm layers such as wool and flannel underneath, and put the shell on only when you need it.
What shoes should I wear on a boat?
Wear flat shoes with soft rubber soles that grip on a wet deck, such as deck shoes or trainers. Avoid heels and leather soles. Flip flops and sandals slip in the same way and leave your feet cold. On a private yacht, ask whether the owner wants non-marking soles before you board.
What should I wear on a boat trip in summer?
On a summer boat trip, wear a cotton tee with a flannel shirt worn open over it, a cap and sunglasses. Glare off the water is strong, so cover up from the sun. Take a jumper for the return trip, when the wind picks up and the temperature drops.
What should I wear on a boat trip in winter?
On a winter boat trip in the UK, wear a cotton tee, a flannel shirt, a wool jumper and a wool gilet or jacket, with your own waterproof shell on top when the spray or rain arrives. Add a warm hat, gloves, warm socks and flat shoes with grippy soles. Keep the layers thin enough for a lifejacket to fit properly over them.
What should I wear on a ferry?
On a UK ferry, wear the same layers as any boat trip and keep the jumper and shell to hand for the open deck, where the wind is strongest. Most crossings have an indoor lounge, so the warm layers only need to cover the time you spend outside. A cap with an adjustable strap stays on in the wind. A loose hat does not.
Is wool good to wear on a boat?
Yes. A wool jumper or gilet keeps you warm in the steady breeze a moving boat creates, which is why fishermen have worn knitted wool on the water for generations. Wool holds some of its warmth when damp, which a wet cotton jumper does not. Wear it under a waterproof shell on wet days.
