I don't think you would like it in good conditions, but it might make a light wind mushy wave day fun. I've checked them out as a surfboard myself and they look great. But they have very little similarities to kite boards, especially the rails and volume displacement is all wrong for a good performing wave board.

Saying all that, I have a friend that rips on the strangest shaped board I've ever seen. So what you think won't work in theory, can actually surprise you on the water.

i was think to use in mushy bay wave and we dont get out in more than 4 foot when where out surfing anny way

any other boards that you could reckomend that are still aboaut 6 3 and are an easy paddle.

I've posted it before, but I ride a 5'10" Xanadu twinny fish. Heaps of fun to surf, and also to kite. It's epoxy so it floats better then glass boards, and is tough. Like the others have said, can be a bit skippy in higher winds, but just use a smaller a kite. You are restricted by the twin fins in terms of back hand snaps. I also kite with a 6'4" and a 6'2" which handle punchier, suckier waves a bit better.

The webber does look like a fun board, though, maybe drop down a size or two. General rule with fishes is to go a few sizes smaller then what you would normally ride.
