In the Cabelas catalog or on
www.cabelas.com, there's the Hurricane Boat Cover Company's 1-800 number, that does the same thing; makes in three different materials, prices & colors from computer memory. I went with the low price model and for about $425. got a cover for my '94 21' walk-around cutty cabin made out of a not-very-breathable grey canvas material and then installed a couple of air vents on top. Breathable and color-choice Sunbrella probably costs a lot more. They asked questions like; high-low bow rails,inboard-outboard or outboard? It fits good.
