Are any of you guys windsurfing with 11 meter sails? I am wondering if I can use a 48cm 105 sq. inch weedfin with one.

No, its no good, you need to give (sell) it to me, if its a deep tuttle job
But with an 11m sail? you may struggle with only a 48cm job, the sail size would need to down in the 8-9m range max, I reckon.

Hi Rubby,
I use a Select Anti Weed 51cm(20") formula weedie(its bigger than it sounds) on a 9.8 Gaastra Nitro 3 with a formula board and it works well.
Check out Select fins as they do bigger weedies than most.

Hi Rubby,

To answer the question about weedys having a wider chord:

As far as I can figure out, big long weedys have a problem where the centre of effort of the fin moves back, compared to a normal upright fin.

This has the effect of making the board want to turn downwind whenever a gust hits you...

JP get around this by having a wide chord at the root, and a narrow chord at the tip, this moves the centre of effort up (and therefore forward because the fin is raked).

As for whether your 48cm will work with your 11m? No idea

Actually, I'll probably be able to hold onto this pig in winds up to 16 m.p.h. I'm overpowered with a 9.6 up to 20, but I can sail rather comfortably in the straps with one at 17-18. I went to a regatta last winter and saw what the big guys can do with 11-12 meter sails. You can be blasting at rather high speeds with them and that is nothing to sneeze at!!! I've contacted a Select dealer who carries the Delta XL and XXL weeders. He chatted on-line with me about it. Now I'm waiting for a photo of an XXL he has for sail that has a slightly damaged tip.
