What it involves
Canvas work covers covers, biminis, dodgers, enclosures and sail covers; upholstery covers cushions and seating. Jobs range from restitching and zipper repair to patterning and fabricating new pieces.
New canvas is usually patterned on the boat, sewn in a shop and fitted back on the boat, so expect at least two visits.
Who does it: Marine canvas and upholstery shops, many of them small local businesses.
How often, in California
- No rule sets a replacement interval. Sun exposure is the main factor: thread and clear vinyl usually fail before the fabric does, so restitching can extend the life of a cover.
What affects the cost
- Size and complexity of the piece (curves, windows, zippers).
- Fabric and clear vinyl choice.
- Repair of an existing piece versus patterning and building new.
- Frames and hardware for biminis and enclosures.
- How many trips to the boat the job needs.

California rules that apply
- In California, labor to make a new item (fabrication) is generally taxable, while separately stated repair labor generally is not. Ask the shop how tax appears on your invoice.[1]
- Some harbors require a permit for canvas businesses working on boats. Santa Barbara Harbor's Business Activity Permit covers canvas and upholstery work and sets a $2,000,000 insurance minimum for major repair work, which includes canvas.[2]
- When a shop takes cushions or canvas off the boat, the customer's property is in its care. Marine insurance programs sell bailee coverage for exactly this.[3]
What to tell a provider
A request with these details gets a more accurate quote and fewer follow-up calls:
- Which pieces: cover, bimini, dodger, enclosure, cushions
- Repair or replace, with photos of the current piece
- Fabric and color, if you have a preference
- Marina, slip and access for measuring and fitting
The free service request brief puts all of this on one page you can print or send.
