You are a keeper, There are lots of men out there that wish they had a wife that buy boat stuff for them. In response to your question. You will probably not find anything that can be purchased 'off the shelf'. Whatever you buy will be somewhat custom and you will need to supply some basic dimensions, such as boom clearance, cockpit width and so forth. I think Boat US (www.boatus.com) does semi-custom canvas. By semi-custom I refer to a senerio where you provide dimensions and they provide a stock product that is the closest match. You might also look in your local phone book for companies that do canvas work on boats. If you find a local company they will usually take dimensions of the boat. They will probably be a bit more costly than a company like Boat US. Sailmakers will sometimes do canvas too.
