What good is a car top boat that weighs 125lbs do for kids that don't have cars? I would bet that mom can't throw the 125lb boat up on top of a car.
A ready to sail weight of 125 lbs doesn't mean that the thing being lifted to the car top is 125 lbs as well. Almost halve that weight is taken up in the mast sail rudders. If the hulls and beams can be easily disassembled we may even be looking at the heaviest single component weighting only 40 lbs.
We must really learn to think in what CAN be done and not trying to find more things that CAN'T be done.
With respect to kids only playing. I've seen large fleets of extremely dedicated youngsters trying to coach as much speed from their boat as possible. I know the sailing culture were I live is different from the USA, but here we tend to have camps with fleets of easily 15 boats doing competitive sailing for days and there a 10's of such camps in the country. A serious event for young people attacts easily very large fleets.
