You may be right about the Hobie class rules, however, I believe the original intent was for righting a boat solo. If racing solo, you would either have to be over minimum weight of around 300 lbs or you wouldn't be racing under NAHCA. If racing under another organization, then I believe the Hobie class rules would not apply.
In response a previous writer, I have not found it difficult to "tightrope walk" Gary's system. If one were to use the one line righting system (single line thrown over the hull attached to the dolphin striker), it would be difficult, however, I use a homemade Hawaiian system. This in effect gives me three balance points, feet, left hand, right hand. This allows balance to be a non-issue. I do realize that others may find it difficult, I just wanted to clarify this.
