Custom Marine Canvas & Marine Upholstery in Key Largo, FL

Calypso Canvas & Sail has been Key Largo’s family-owned marine canvas and upholstery shop since 2006. From our shop at 103530 Overseas Highway, we build custom boat canvas and covers, Bimini tops, T-top enclosures and marine cushions, and handle sail repair and boat canvas repair for boaters in Key Largo, Tavernier, Islamorada and throughout the Upper Keys.


Every project is templated to your boat and built with marine-grade materials, including Sunbrella, Stamoid, Strataglass, marine vinyl and closed-cell foam, so it stands up to Florida Keys sun, salt and time.

Why Professional Marine Canvas & Upholstery Matter in the Florida Keys

Marine environments are punishing: constant UV exposure, salt spray, moisture, and temperature swings accelerate fabric breakdown, corrosion, and mold growth. Investing in professional canvas and upholstery protects your boat’s interior, prolongs hardware life, and preserves resale value. Properly designed covers and awnings block UV, reduce interior heat, and prevent water intrusion. Quality upholstery restores comfort, supports marine-grade hardware, and resists mildew. Expert repairs extend the life of sails and canvas while maintaining safety and performance for your vessel.

How We Build and Repair Your Marine Canvas & Upholstery

Consultation and assessment

Call (305) 942-6252 or (305)-923-6182 to schedule a free consultation. We begin with a detailed assessment of your boat and usage patterns, discussing priorities like UV protection, water resistance, breathability, and appearance. For repairs, we inspect damage, fabrics, attachment hardware, and structural concerns to recommend the most cost-effective, long-lasting solution.

Custom design and templating

For every new cover or upholstery job, we create templates—either on-vessel or using precise measurements—to ensure perfect fit and streamlined installation. Our templates account for railings, hardware, antennae, and any unique vessel features, ensuring covers and enclosures fit snugly and perform as intended.

Material selection and recommendations

We recommend materials based on the application: heavy-duty, UV-resistant fabrics for exterior covers; breathable, fade-resistant fabrics for interior upholstery; clear, high-clarity Strataglass for enclosures; and closed-cell or marine-grade foam for cushions that resist water absorption. We guide you through color, texture, and hardware choices to align with function and style desires.

Fabrication and installation

Our shop is fully equipped for precise cutting, sewing, and assembly. Skilled technicians use marine-grade thread, reinforced seams, and professional attachments such as stainless snaps, zippers, and elastic hems. We provide on-site installation when needed and off-site fabrication for larger projects. Each project includes a post-installation check and care instructions.

Repairs and maintenance

We handle sail and seam repair, boat canvas repair, zipper replacement, restitching, boat upholstery repair and foam replacement. For longer-term care, we offer maintenance plans to inspect, clean and treat fabric to prevent deterioration.

Approximately 30% of our work involves duplicating a customer's existing canvas or upholstery. If you love your current boat cover, enclosure, or cushion but it's worn out or you need an additional one, we can replicate it exactly. We can also copy it with modifications — lengthening it, widening it, or altering the shape or fit as needed. Copying an existing piece is very common in the industry and a great option if you're happy with what you already have.

  • What materials do you recommend for boat covers in the Keys?

    For long-term UV resistance and breathability, Sunbrella and similar acrylic fabrics are ideal. For clear enclosures, high-clarity Strataglass with proper reinforcement is standard. We’ll recommend materials based on whether the cover is for storage, active use, or display.

    With proper materials and care, marine upholstery can last many years. Sun exposure, maintenance frequency, and how often the boat is used influence longevity. Regular cleaning and protective covers significantly extend life.
