I have a "D" shaped tube. It is good for two people and a whole lot of laughs. My wife saw the video from the Manta Ray and wants to try and get one. the problem I told her was I didn't know if our boat was big enogh for that. I have a sportster scic and was wondering your opinion.
I wouldn't do that. It is just that my friends have a pontoon boat and a 3 person towable. Their boat is older and not much fun to tow behind. They were wondering if I might be able to use it behind mine. I guess the only way to find out is to try.
