Pete, those are the tradeoffs when you race Uni. Naturally a crewed boat can get the spinny up faster as the crew is already pulling the tack and hoisting while the skipper is driving to the offset mark. Same with the douse, the skipper can hold a high line and trim in the main, going fast, while the crew snuffs it, then resets the rotator, downhaul, boards down if they were up, etc.
The "payback" when sailing Uni? It's more of a challenge, when you get it right you can feel good about yourself.
And when you swim...well...you can't blame the crew!
I would prefer to have a 5' tall, 100lb. super crew who could do all the hard work, all the time, while I just drive. But since I don't know anyone like that...I'll continue to sail Uni and be happy when I get it right.
