RE: Board Selection - Totally Confused
OK, now we can get somewhere.
At 110 kg./242.5 lbs you definitely need the "big boys board"
So, now we need to decide if you want a centerboard or not.
There are a number of boards with adequate float that have centerboards, but maybe it would be better to get a much larger rig go try out your HiFly Motion in some windier places.
Then, when you are planing nicely on the Motion, look for a GO 185
(GO 185 185 liters; 253 cm long; 99.0 cm wide; 67.5 cm 1'off tail
Weight ? 6.5-11.0 m2 sail size range).
At your weight I'd suggest you look for at least a 9.5 m2 rig.
The main things that keep you from planing are you size vs the tiny sail size you are using on your Motion. I'm sure the board is up for it, you just need to get the power to get it all moving faster, in less wind.
Even very experienced sailors that weigh 110 Kg don't get planing much before 12 knots with jumbo sized sails and you have about "half a jumbo" with your 6.3 m2 rig.
You can get a larger wider more floaty and high performance board, but you need the big rig first.
Get the big rig, get comfortable on it with the Motion, then go looking for a ligher more hi-performane board.
When you are hooked in and in the footstraps with the center board full retracted and planing along, then go look for a different board.
The HiFly will plane, even for a guy your size, you just need a big rig or alot more wind.
Sorry, I know this isn't the answer you probably wanted, but it's the facts.
Hope this helps,
