Bob,
I must say you have hit it on the head.
The rigging of a boat can be quite a social occassion.
Usually takes twice as long as needed, not because the boats are that hard to rig but because of all the talking that goes on between rival crews. At least that is the way of it at my club.
This brings up an novel article I read in an old Paper Tiger Newsletter. They posed the question.
"Are Beach Wheels in the interest of the sport?"
The issue was the beach wheels meant fellow Paper Tiger sailors didn't need each others help to get the boats in and out of the water and that could impact on the social side of the sport.
After all - don't we use the race as an excuse to Sail and Socialise.
