Doug, to reply to your question about crew wt. on the F16, if it's windy (15+) then 360 lbs. is not too heavy and may in fact help you go faster than the lighter crews depending on how much they have to depower the boat. I would not recomend the Inter 20 for an inexperienced female crew unless she loves pain, in which case, does she have a sister?

The one thing about the F16 as a class, you can race it solo if you can't find crew, or two up if you can. The Blade will easily handle 360 lbs. crew on board, you might not be as "fast" in light air as a lighter team, but you never know. In the end, it comes down to sailor skills, which is how it should be.

The Inter 20 is a great boat but you must race two up all the time so you lose the option of racing solo if your crew bails on you. And there is that moving it around the beach issue as well.

I think you have said your grand-daughter sails with you, well you two should be fine on any F16 platform, and then if she's not available, you can race solo as well.

Running the spinnaker on the F16 is of course easier than on the I20 just because the spinnaker is smaller so it takes less arm strength, but on a windy day, she will have both hands full, ask Gina!
