Anyone who has tried to fit a regular sheet onto a boat bunk knows the problem. The mattress narrows to a point, the corners are cut at odd angles, and a normal rectangular sheet simply will not stay on. A V-berth fitted sheet is cut to match that triangular shape, so it hugs the mattress and stays put even in a rocking cabin. Here is what to know before you buy one.
A V-berth fitted sheet is shaped to fit the triangular bow mattress of a boat, with deep pockets and all-around elastic so it grips a narrow, angled berth. Ours starts at $49.99 and comes with a 100% Fit Guarantee.
Why a regular fitted sheet will not work
A standard fitted sheet is built for a rectangle. A V-berth mattress is shaped like a wide arrowhead, narrow at the bow and wider toward the cabin. When you stretch a rectangular sheet over it, the extra fabric bunches at the point and the elastic cannot grip the angled sides. It pops off the moment you move. A V-berth fitted sheet is cut and sewn to that exact triangular outline, so the pockets sit where the corners actually are.
What makes a good V-berth fitted sheet
- Correct triangular cut. The sheet must match your berth outline, not just approximate it. A true V-berth fitted sheet follows the bow angle.
- Deep pockets and all-around elastic. Boat mattresses vary in thickness, and 360-degree elastic keeps the sheet gripped through every wave and roll.
- Breathable, moisture-friendly fabric. Cabins get humid, so a breathable cotton weave helps the bed feel fresh and dry.
- The right size name. Berths come as V-berth, After V-berth and XL V-berth. Measure and match, or choose custom if yours is unusual.
How to measure your berth
Measure three things: the length down the centre from the bow point to the cabin edge, the width across the widest part at the cabin end, and the mattress thickness. Take the measurements on the bare mattress and round to the nearest inch. If your berth does not match a standard size, a made-to-measure V-berth fitted sheet is the safe choice, and the 100% Fit Guarantee means it gets remade if it does not fit.

Frequently asked questions
What is a V-berth fitted sheet?
It is a fitted sheet cut in a triangular shape to fit the bow mattress of a boat, with deep pockets and all-around elastic so it stays on a narrow, angled berth.
Can I use a regular twin fitted sheet on a V-berth?
Not well. A rectangular sheet bunches at the point and slips off the angled sides. A shaped V-berth fitted sheet is the only thing that grips properly.
What if my berth is an unusual size?
Choose the custom made-to-measure option. With the 100% Fit Guarantee, it is remade if it does not fit, so an odd shape is not a problem.
How do I keep boat bedding fresh in a humid cabin?
Pick a breathable cotton sheet, air the berth when you can, and wash regularly. Natural fibres handle cabin moisture far better than synthetics.
