I love sailing with someone else who knows what they are doing in high winds. However, if I only sailed with someone else I would sail about half as much. I used to think I wouldn't like sailing solo but I certainly do. I couldn't do it if my boat weighed more than it does. Pointless to have a boat you can sail solo but still need 2 people to get it in and out of the water.
As more people feel the thrill of sailing solo downwind with the spin up from the wire I think more and more people are going to be interested in single handed spin boats.
