i had canvas craft quote making me a replacement Thermal
shell for a clam scout. Its a small one man shelter. They charge 100 bucks for patterning the old tent and then it would be roughly 350 to make it. So 450 total. I can buy a new canvas craft bigger one man with sled seats and poles for about 550. I think you would be better off just buying from otter
. You may be able to get the wild shell with just the Thermal
top. Good luck, but making a one off at a canvas shop anywhere would be expensive not just canvas craft. you could try a custom boat cover maker.
