Weed Fins

I have a JP 31cm Weedy which works great - they're machine cut out of G10 and are very strong and damage resistant (exactly what I need). It looks like the largest they do is 36cm - I don't know if this would be big enough for your board - take a look at the JP site:

Another good one is the Choco which comes in 40cm - checkout:

I had a GO 160ltr and used what I remember was a Select weedy. I can't remember the size, but it worked really well. Jezz at 2nd Wind would know what size to use. Send him a PM. They are site sponsors.

Hi All,
for a couple of years now I have exclusively used Select weedfins. I use a 22 (sometimes a 30) in my Starboard Sonic 85 and a 30 (sometimes a 32) in my Starboard Hypersonic 105.

The rake angle of the Select guarantees shedding the 6 x 1/4 inch eel grass we get at Pt Henry.

In my opinion the Selects are a great for blasting and freeride and an excellent beginner to intermediate fin. I say this because they give heaps of notice before spinning out. You can feel them go squishy, at which time, if you reduce back foot pressure and unload the fin a spin out is prevented. If you do not heed the warning the fin kinda says 'well I warned you' and eventually lets go. However, they continue to hold enough lateral resistance (probably due to their width) so that the board merely points at 45 deg to your track, again giving you the opportunity to take remedial measures to re-engage the fin. Usually, by yanking the tail of the board back under your butt with your rear foot and both feet still in the straps, or taking your back foot out to assist pointing the board downwind works. The point being a spinout with this fin does not automatically result in a crash.

The Flying Objects Weedster is not as wide and has less of a rake angel than the Select, yet It seems to effectively shed the type of weed we get (note - after making the mod Frant suggests. That little gap on the front edge it a great weed collector)

If you have a more performance or speed focus, the Select will be limiting. I borrowed Frants Flying Objects 26 G10 Weedster the other day, combined it with the Sonic 85 and a 6.6 SSR and found it to be more solid than the Select. It provided the almost (8/10) same positive feel and confidence as experience with an upright fin, in this case the Drake Slalom Pro 300, the Sonic 85 standard supplied fin. The FO was definitely a couple of klicks faster than the same kit on the Select fin.

Back to your original query OB64. I would go for a Select 30 or a Select 32 Weedfin for now. They are very forgiving to sail and cope with heaps of abuse, like running them into the sand. In a couple of years when you have worn an inch or two off of the bottom of it and your sailing objectives change, take a look an alternative.

I am going to get a Select 32 or 34 weedy this week and see how I go.

I am also very tempted to cut one of the Drake fins I have and re-pot it at a 45 degree angle just to see how it goes. I made a mold for the tuttle box which produced a couple of trial fins without too many problems.

With the low tides on Lake Connewarre we are experiencing at present a Select 32 is as big as I would go. You might find dragging through the mud everywhere a problem otherwise. Check out the fins at 4 Winds as I think they might have a 32 for a good price.

How do you know what size fin to use with what size sail and does it make a difference
