Welcome to Gemini Marine Canvas

Not your average canvas shop

At Gemini Marine Canvas we couple award-winning design with high-quality materials to offer the best custom canvas and upholstery for your boat, home and business. Our crew has decades of combined experience creating beautiful custom canvas and upholstery for hundreds of boats, many of which belong to repeat customers.

We’ll help you choose from hundreds of fabrics, foams, fasteners and fixtures, with as much or as little guidance as you’d like from our skilled and friendly staff. We only use the best for a polished finish that will last for years, including:

  • Sunbrella and Serge Ferrari Stamoid fabrics and vinyls
  • Strataglass and O’Sea windows
  • UV-stable Tenara thread
  • Our own patented 316 marine-grade stainless steel hardware

So sail or power, indoors or out, big new builds and small repairs, our quality speaks for itself – and we’re here all year round. 

“This is just a quick note giving you feedback on the new canvas enclose on Annisquam III. It works great!! It allows us room to move around when totally enclosed, just what we were looking for. We just love it and thank you.”
