Wow, I could really use something like that on my CV. I had no idea there was such a thing. Is it actually called a Cargo Wing?
The top is up in the picture on the right...As long as it works with the top up. Otherwise, other than wakeboarding/kneeboarding/water skiing, I can't see much use for it. Looks like it would only also hold Snowboards/Skis. And I feel that water sports are not as widely done as snow activities.
