As a personal opinion, any babe who can sail like Lucy should get a LOT of bonus points in comparison to the ones who can't sail.
I mean, the point here seems to be attractiveness tempered by someone who is lots of fun at the beach. All of your Babes would get more than a few looks, but that is not what distinguishes a *Boardseeker* Babe.
So I think there should be bonus points awarded based on their windsurfing ability. On that basis, Lucy (and several others) deserve a lot higher scores. I suggest the following scale:
World Champion / Olympic Champion: 20 pts
Euro / National / Etc. Champion: 15 pts
Hard core sailor, advanced-to-expert: 10 pts
Intermediate-to-advanced / has her own board: 5 pts
Beginner / has tried it: 2 pts
Will accompany to the beach: 1 pt
No windsurfing attributes: 0 pts
