Sounds like they had a great time.
My son is a Cub Scout, and I can relate to the limited attention span of
that age group. Still, I would like to do something similar w/ my son's dens in the future.
Knowing how the kids are I am not surprised that they enjoyed the Wave over the larger mono's. The larger boats were likely more complex, had a a ton of 'wierd sounding' control 'ropes', and required seemingly alot of work to go not-so-fast.
The Wave on the other hand, while bieng a wet boat (a plus for kids as they love to get wet, 'who cares about the temparature'), is extremely stable, easy to understand, you can move around without upsetting balance too much (try that with any 13' mono), very forgiving, and surprisingly quick. I know, you can't compare it to a 16, but then again, you cannot get 4 people comfortably on that cat, and
it scares even some experinced sailors.
I have taken several people out on my Wave, ranging in age from 4 to 70, and everyone comments on the surprising speed. The kids just love to hang off the shrouds and drag thier feet off the crossbars when they tire of taking the tiller, etc.
I hope to get a few people turned on to the sport through the experience on my little Wave.
So, congrats on a job well done!
