I've found a board 125ltre Tabou Bullit. It has a stock 44cm Tabou fin but I need a weedy to sail Coal Point.
Powerbox. I think the board is 70cm wide.
What size 44cms or?

Easy , Fangy 24 . And it won't let go in the rufff .

Tribal Weed Speed 33. The 33 is the depth of the fin in cm. It's length is about 40cm. This should work with sails up to 7.8.

Tribal site has a chart that I find good as a starting point. Weight of rider should also be considered too.

Considering the average age of this sport is pushing 50+ you'd think they would have made their chart in extra large font

Thanks. I'll keep an eye out. I was wondering why the quoted sizes were so short . It make sense if the length is longer .
That will get me upwind slogging?

I have the Bullit 125 (2017),and only used weed fins on it, due to local WA condtions.Last time out a great sesh with 7.3 and 40cm vector weed slalom,generally for blating around i don't use smaller than 6.6 or 7.0 on it with 36 JP weed.
Have used with 8.3 and 42 JP weed which works well.
I have lighter and racier boards which I have Tribal weedspeeds for but are all Tuttle box so unfortunately can't try, on
my bigger board 138l speedster 85 wide,I use 43 weedspeed with 7.8/ 8.3, for comparison.
I'm around 90kilo (after a big feed ),hope this helps

I run a 36 Vector Weed Speed in my JP Slalom 133 litre if that helps.

Flatwater or chop ? Is chop how big..

Sue, I run my Tribal weed speeds in full Moreton Bay Chop (up to 1m confused chop) which is similar to full Lake Macquarie chop

I've ordered a 38cm Tectonics weed demon. I use a 35 in my WT 64 ( 112ltres) and I'm very happy with it.
I took a punt and went the larger size with the Tabou as it will be a very light wind board- 5 -13kts..

Awesome fins these,I have a couple in smaller sizes, would be very interested to hear how the 38 goes in the Bullit
