I find that very odd too, Mary!
On our beach it's always the guys (boyfriends/husbands) who are sailing, wives / girlfriends are usually sitting on the beach sunning themselves. We have very few really pro-active female sailors. I'm not counting those women who ocassionally go sailing with their menfolk for a romantic evening cruise in no wind.
The pitiful "sailing" club (its really a drinking club with a sailing problem, LOL!)we still have also does not have any active women (other than a crew who's a wife or daughter of a skipper).
I find that very disappointing also.
