Default RE: Uphauling a 10 m sail on shortboard (iSonic 133)

Hi Thierry

The FT138 is more compairable with the iS145 & iS155 (both of these are replacements for the F-types and are not "true" light wind slalom boards). The FT138 has much softer rails than the iS133 (a true light wind slalom board). The iS133 has harder rails and like your iS105, it will track up wind better than the FT138 (I always felt that the F-Type used to slightly slip side ways if push to much). The iS133 will feel much crisper than the FT138, but less forgiving.

Uphauling an 8.5m on your old HS125 would have been easy. I have uphauled a 9m wide sleeve race sail on both my old HS105 (it did sink though) and HS125 with no problems.

Speedwise, on flat water, I have touched 31 knots on my old FT158 with my 9m and 49cm Select Superfast fin (not a special fin), so the FT138 should be pretty capable in the right conditions with a bit of tuning.

Cheers
