Isonic 133 what fin size for sail size.

Nick F · 29th May 2010, 04:33 AM

Hi, Could anyone please tell me what size of fin I should use for my isonic 133 when using my Tushingham lightning 9.4 and TBird 8m sails.
I am 95kg and power off the fin a lot.

When using the 9.4 sail I used a 48cm fin and found it would not give me much grip, if thats the word I am looking for, but changed it for a 52cm and was better, I don't know if this is due to putting to much pressure on the fin.

Also what size would you recommend for a 6.5 sail ?

Sorry, you have probably heard this question a thousand times before, but would be very grateful for some help and advise.

One more thing, when I bought the board it is for deep tuttle fins, why do you get tuttle fins with it and not deep tuttle.

Thanks

Nick

First;
you need a 50cm fin with your 9.4 for downwind racing. For match up racing with your friends you can go with 52cm.
I recommend this two brands www.vectorfins.com and go with the canefire in carbon molded.
I also recommend www.f4fins.com and there you go with the D2 in carbon XS.
Second:
I will never use that board with a 6.5m sail. Will only use it with 8.m sails and bigger all the way to 9.8m.

Many thanks for the info. I use the fin off my futura 144 which is 52cm drake, I don't know if I would notice the difference in fin manufacture, due to me not being a pro, and would cost a lot more money for these fins ?

Thanks
Nick

The fin for the futura is another type of fin not design for the iSonic. It would work but it wont make you board release as it would with a good slalom fin.
I will never use a Drake as they are crap production fins.
