So that is what I have done. Now if you are going cheap there is Leta's top shop. She has Maxum templates but you have to put on the snaps. It can be hit or miss with the fit and quality, your choice!
I agree completely. There are no 'off-the-shelf' options. The only option is to have it custom made.
Leta and a few others (I would balk at the use of the word 'cheap') use the Maxum templates to make factory identical canvas and isinglass. The challenge here is you don't know if you have a factory canvas or a custom canvas. For example, I replaced my bimini a few years ago. I doubt mine matches exactly with the factory pattern anymore. Now, If you're replacing the canvas AND the Isinglass together, this is probably not going to be a problem. The problem occurs when you attempt to attach factory isinglass to custom bimini or vice versa.
We have someone on the site dealing with that very problem right now. Canvas typically last about 10 -15 years. If your boat is that age or older and the canvas looks fantastic, it's probably been replaced.
Like Roger, I use a local canvas shop. They come out and take many, many measurements and use a plastic to make a template and mark it with sharpie. Then they go back to the shop and knock the piece out.
