Ive been requested by alaskamokaiman and flathorn for a picture of my top. It was built by custom canvas in fairbanks. It actually fits better than the pictures make it apear but the day I took the photos it was very cold so I was afraid to strech it to much. they did a excelent job but they way over built it. You could tow it down the highway at 65mph or tie a zodiak on top. It also cost alot $550. They said if they ever did anouther one it would be $650 (winter of 06/07). I would never use it in a river because I think it would be to hard to get out of if you flipped it plus I think it distorts your visability enough it would be hard to read the water for shallow spots. In the ocean it works very good you stay compleatly dry in the rain and going through the waves.
