decided to do a post on HOW TOO make a weed speed fin 45+deg wide profile in the speed section until c3 posted there proto , very much similar to mine

so far to my knowledge the only fin like it is the MFC and there 55deg rake , just a bit to much for my liking

these wide, low profiled fins around 22cm or less will drive a 7.5mt sail in chop, and cut through weed like your grandfathers axe
the biggest problem with your normal weedy to drive a bigger sail through weed, it just doesn't do the job
ive almost got enough data down to show you how to make make your own , its been a slow process because i have had to make a fin from scratch only a week ago, it should be ready too box in a couple of days , then ill post the pic's
this is an excellent time of the year to knock up a project, we will have the westerly's here(illawarra) around june and you will need a shallow weedy
