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 over 87 years 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 – like Sunbrella and Serge Ferrari Stamoid fabrics and vinyls, Strataglass and O’Sea windows, Tenara thread and our own patented 316 marine-grade stainless steel hardware – for a polished finish that will last for years.

Our team has the ability to craft any marine canvas, cover or seating from simple to complex. New projects to refits/recovers. Implementing traditional skills handed from father to son, alongside training and working with top leaders in the industry. Always utilizing the latest fabrication and design technologies.
