View Full Version : Please Help iSonic 2008 101
24th October 2007, 11:42 PM
I just bought an iSonic 101 2008 and I have North Sails RAM F8 6.3 and 7.3. My board will arrive in January and it has 2 Drake Fins with it (36 and 42). I am 60 Kg. What do you recommend for the fin size ? Is 36 and 42 okey or do i need smaller fins?
(I usually sail between 13-25 knots) So what do you recommend for different winds?

For iS101 and 60kg a general or typical range would be
40-42cm = marginal to light 7.3m conditions
34-36cm = powered 7.3 conditions/light 6.3 conditions
32-34cm = powered 6.3 conditions
30-32cm = overpowered 6.3 conditions
You don't need all these sizes, it's simply an indication of how the iS101 would be tuned for your weight and sail range. Of course, there is tolerance (at least +/- 2cm) that needs to be taken into consideration because of rider style/technique/strength, plus wind (solid vs gusty) / water conditions (flat vs choppy) and sailing program ; slalom ( Fig 8 or downwind?) or GPS speed or just blasting. And of course the actual fin make/model for a given cm size has influence on "performance" size.
It's not clear what your previous board was, but in general iS101 sets up best with a little more fin than narrower (or narrower tail) slalom or freeride boards of similar volume and range.

Thanks for your quick reply. I windsurf in Alacati / Turkey. As you may know if you've surfed there . It's a little choppy in strong winds. I guess I may need a 32cm or 34 cm fin also. So what fin do you recommend?

For 60 kg I would recommend 32cm, it just allow you to trim the board in radical/choppy conditions a little easier. You can use a slightly more raked fin in that mode too, it won't cost you much in speed in rough chop, but can make a big difference in control/confidence. Look at Deboichet SL3 or similar.
