We are boat bedding experts. Our CinchFit Sheet design works perfectly on thinner boat mattresses. We created Universal V Berth sizes for sheets and bedding to allow boaters to easily order bedding for their boats. We can make custom boat sheets for any shape or size mattress and do not need a template. Our products are hand sewn in Brunswick, Maine. We provide exceptional and personalized service .
