Tri-Hull Boat Cover

[mercurymang]

Anyone have any advice on a tri-hull boat cover. I purchased one at academy for under $100 that said it was for a tri-hull but it didn't really look like it for a tri-hull to me. More like a reguler v-hull type fit. I was able to make it work but it filled up with water during a recent rain storm (had not put my stand-off's in the boat) and it ripped. So now I would like to know if anyone else has a trihull cover that fits well and that they are satisfied with.

thanks
