Below is a Straightforward Solution in Making Boat Bedding:

Mostly all yachts are long and narrow thus, it has only a very little space for beds. There's not enough space for storage and cabins for small boats. V-berth boats, its bunks are surrounded by three sides.

You must measure the exact dimensions of the boat mattress. A detachable top cushion is usually found in a V-berth boats. You must detach the cushion and get all the dimensions remember, you have to be precise.

you need to tape a right amount of butcher paper to build a design. Be sure to put a 1 inch allowance on each side to be sure that the sheet will fit under the boat mattress.

Be sure to trace the form on the flat sheet exactly and put a little allowance on it. When the V-berth is close to the size of a full bed then you can use a queen size sheet to cover it.

You have to make a square cut on every corner to cut it out. Make sure to turn the curve under when sewing the elastic to make space to make those corners.

Matching the two cut ends at every corner area then sew them as a group forming a pocket.

out fold the edge of the sheet over the elastic using straight pins and sew the elastic hem into its edges.

To make it easy, you can just sketch the outline of the boat mattress on the sheet and measure the exact dimensions of the boat mattress.

You use a sewing machine to make sure that all stitches are uniform and its more durable.
