Looks like it's time for ...
A whole new suit of sails, not just a genoa.
Thorough bottom cleaning.
Performance sailing classes for you, the wife and kids.
Bring some neighborhood kids along to sit on the rail.
And, if all else fails, a huge fan for the foredeck. I've read that works.
I can't believe all these guys are trying to talk you out of spending $$$$$ for another half-knot of VMG. What's happening to this place?
Don't stop there! install w/w sheeting traveller....adjustable sheet leads....V/C offshore paint, after stripping, fairing and epoxy barrier coating the bottom..New vang..adjustable backstay...remove all un needed items such as cushions etc. fare in all thru hulls wet sand paint to 800 grit and burnish with news paper and you should notice a few 10'ths of a knot.
