For a day on a boat, wear three layers: a base that dries fast, a mid layer that keeps you warm and an outer layer that stops the wind and spray, plus a cap, sunglasses on a strap and shoes that grip on a wet deck. It is always colder on the water than on the dock. The wind strips heat from your body, spray soaks your clothes and the weather can turn in an afternoon. That is why the sailor's rule is simple: not one thick garment, but several layers you can put on and take off. This guide is for day sails and coastal sailing. For passages or truly bad weather, what you need is proper technical sailing foul-weather gear.
What to wear sailing, by the conditions
| The day | What to wear |
|---|---|
| Sun and a light breeze | Quick-dry tee or polo, cap, sunglasses on a strap, a light layer in the bag |
| Wind and spray, no rain | Quick-dry base, vest or sweatshirt, softshell on top |
| Showers and changing weather | Base, mid layer and a light hooded jacket that packs small |
| Cold days | Base, a warmer mid layer and something quilted, plus gloves |
Layer 1: a base that dries fast
This is the layer next to your skin, and its job is not to stay wet. Cotton absorbs water and dries slowly, so on a day with spray a quick-dry technical fabric works better. The Beaufort tech tee is quick-dry and breathable, in 100% polyester piqué, and carries a force of the Beaufort wind scale on the back, the one you choose.
Cotton still has its moment: on the dock, on board on dry days and ashore after sailing. That is what piqué polos are for, like the Cinew, in 210 g/m² combed cotton, or the Redor, in 100% cotton piqué with a contrast collar, cuffs and placket. If you want to know why the polo is knitted that way, read what piqué is.
Layer 2: a mid layer that keeps you warm without getting in the way
Its job is to hold on to your body heat. On board you want it to leave you free to move, especially your arms, because you will be trimming sheets, handling lines and holding on. A vest is a good choice: it keeps your core warm and leaves your arms free. The Sogilet vest stretches with you, in 95% polyester and 5% elastane, with no padding and no lining, a stand-up collar, a YKK zip with an inner windproof flap and two zipped pockets.
On a cooler day or for the sail home in the evening, a zip-neck layer works well, because you can open the zip to let heat out instead of taking it off. The Zipes half-zip sweatshirt is brushed fleece in 60% cotton and 40% recycled polyester, around 290 g/m², and the Camray is a quarter-zip knit in 100% cotton. Both contain cotton, so keep them under your outer layer when there is spray. What matters is that you can take the mid layer off when the sun comes out or when you start working hard, and that it fits in your bag.
Layer 3: an outer layer against wind and water
This is the layer that protects you from the wind, which is what chills you most on the water, and from spray or rain. Choose by the day:
- Wind and spray, no real rain. A softshell. The Stortex jacket has three layers (a hydrophobic outer face, a breathable middle layer and a micro-fleece lining), a windproof, water-repellent finish, a high collar with a chin guard and a drawcord hem.
- Showers and changing weather. A light hooded jacket that fits in your bag. The Sarbon is water-resistant and windproof, with a breathable mesh lining, an adjustable hood and velcro cuffs, and it packs down small.
- Cold days. Something quilted. The Oceania quilted parka is 100% RPET (recycled polyester), with a foldaway hood and fleece at the collar and inside the pockets.
Not sure which of the first two you need? Our guide to softshell or rain jacket compares them side by side.
Head, eyes, hands and feet
- A cap or hat. On the water the sun reaches you from above and bounced off the surface. If it is windy, keep it on with a cord.
- Sunglasses on a strap. For the glare off the water, and because sunglasses that fall overboard do not come back.
- Sailing gloves. If you will be handling lines, they save your hands.
- Deck shoes. Soles that grip on a wet deck and do not leave marks.
Before you go
- Check the marine forecast and the expected wind force. Our Beaufort scale guide explains what each number means.
- Bring one more layer than you think you will need, in a bag that keeps it dry, such as a roll-top backpack like the Mironte, in water-repellent recycled polyester.
- Leave a dry change of clothes for the way back. You will be glad of it in harbour.
- Your lifejacket goes over everything: choose layers that let you put it on and adjust it properly.
- Learn a few words before you step aboard: port, starboard, windward and leeward. Spray comes from windward, so that is the side where your outer layer earns its place.
Common questions
Can I wear jeans on a boat?
For a short, dry outing, yes. With spray or rain, denim gets heavy and cold and takes a long time to dry, so lighter trousers or shorts that dry faster are more comfortable.
Is cotton a bad idea for sailing?
Not on a dry day or ashore. Next to the skin on a wet day, a quick-dry technical base is better, because cotton holds water and stays cold.
What shoes should I wear on a boat?
Deck shoes or trainers with light, non-marking soles that grip on a wet deck. Avoid heels and black soles that leave marks.
What should I wear sailing in summer?
A light quick-dry tee or polo, a cap and sunglasses, sun cream, and still one light layer in the bag: the breeze on the water is cooler than it feels on the dock.
Do I need full foul-weather gear for a day sail?
For coastal day sails a water-resistant, windproof jacket is usually enough. For long passages or heavy weather, use proper foul-weather gear.
In short: a base that dries, a mid layer that warms and an outer layer that stops the wind. With that and a good forecast, the rest is enjoying the day.
