I tried the slingshot glide out and it is amazing. The glide needs less wind than any other board I have ridden (even my surfboard). It is basically shaped like a rectangle with 4 .5 inch fins on it's completly flat bottom. I think the board was designed with a skim board in mind. If you become overpowered this is not the board to be on. It tended to slide out with the gusts.
Just an opinion
