Another Note on this
The local guys can be better, or they can be complete hacks. Ask to look at boats that they have already done. Don't assume that because they are local that they are good.
I have had them drill holes completely through the deck, and that tell me quite frankly that they had no idea how to fix what they have done. I have had them finish 1/2 a sail cover, (No fastners what so ever), and claim that they were done. I could go on and on and on and on..... My favorite was a client that brought drawings of what they wanted, complete 3-d renderings, asked if they canvas person could do that. Measurements the whole thing. Autocad printouts etc. It looked really good on the drawings, and on the photographs that they had rendered it on. The canvass LOCAL canvas person that is highly regarded here said; "That looks great, I can do that, but it is going to cost you extra". They said fine and paid hamsomly for the "extra" of not having it designed by the guy. He created and installed something that was not at all like the design, as a matter of fact it looked identical to another boat he had recently completed. They made the mistake of paying all up front. He agreed to do it all again. 8 months later he got around to it, and still did not do it to match the drawing which he still said he could do. They had to threaten to sue to get their money back.
The other thing I do is I NEVER pay a canvas guy everything up front. I have had way way way too many unfinished jobs that way. The final fit is done when I say it is done, not when they get another dodger to do on another boat.
Another thing that I don't like is that they often want low dodgers with lots of canvas and small windows. This does look better if done right, but it makes the boat harder to sail, a lot harder to dock, and really doesn't add all that much in the way of aesthetics in my opinion. A lot of these dodgers I find are really worthless, and just cover the companionway. They funnel spray into the eyes of the helmsman in a real blow, and off no protection for the on watch who can't fit under them.
