54 kg Rider - Formula Board necessary for super lightwind planning? - Page 2

mac33 · 24th February 2010, 02:05 AM

at 54kg a 7.5m is huge.

a 80kg person will benefit/plane quicker from changing from a 7.5m to a bigger size say a 9m or 10m.

for you the benefit will be much less.

if you want to plane earlier, rig your 7.5m sail fuller.

buy a carbon fibre ultra light board!

i use a fanatic 75 wide by 275 long, this board with my 7.7m is big enough for my 67kg.

including straps it weighs only 8.5kg.

found using sails of 9m plus to be tiring and not very enjoyable.

if you do buy larger sail, a sail with less battens/cams is easier to use.

It's certainly too small to start planing as of 6 knots of wind.

Again, your combo is for sure way too small to plane as of 6 knots of wind. With a 77 cm wide board and a 7.7 m2 sail, I need 11 knots of wind to start and sustain planing with my 65 kg. With the same board + larger fin and a 11 m2 sail, I need 7 knots of wind. To plane as of 6 knots, I need a Formula and an 11m2 sail. The difference between planing in 11 knots or in 6 knots of wind is huge: 4 Bft vs 2 Bft wind.

I'm pretty sure Morane can plane as of 6 knots of wind with a Formula and a 10 m2 sail, but the initial question was whether a Formula is mandatory to achieve this goal at 54 kg. Let see what Morane has to say about that.

Cheers !

Is it really true that the sonic 131 will plane earlier than the futura 133 with for example element 8,5 or the ncx 9.0?

Both boards in wood carbon....

Shorter, wider, sharper rails, bigger fin will plane earlier with good pumping technique
for sure, but if you don't pump or more passive in your sailing style it will be about the same

Could an iSonic 131 WC take an 11m2 ? I think that this board might be a better option for me than a full on formula board as I own a 7.5m2 sail which should work better with an iSonic 131 than a formula. If this iSonic can take this huge sail then it could be quite versatile with my 7.5m, giving it a pretty massive windrange.

agrelon · 14th March 2010, 09:44 AM

(You mentioned taking an 11m2 on a board that is less wide than the 131, 77cm as opposed to 85cm, so I guess this setup should work in that respect.)

Agrelon. I'm using a iS144 with 9m, 10m and 11m. 51cm and 57cm fins. I'm 105kg and 194cm. I guess this will be similar in sail carrying ability to the iS131 since there's only 8 litres difference in volume.

On the iSXXL, an 11m gives no real extra "early planing" benefit c/w 10m. This is due to the extra weight drag etc. 10m is the optimal max sail size for iSXXL. It'll work, but not to any advantage. Slogging with an 11m is no fun either. For me, the iS144 is best with a 9m/51cm fin. Light wind heaven

If your looking to get out on an 11m pretty often, but dont want to go full formula, take a look at the iS150. I once borrowed an iS150 from my local shop. I was very impressed with it. It does feel a lot bigger than the iS144 so will comfortably take an 11m, but I think it will be to big for your 7.5m. 9m would be the smallest real size for the iS144.

Even though SB state 6.5m to 10.5m for the iS131, its real usefull range is 9m to 10m (maybe 8.5 to 10m). I think you struggle to find a board that will truly work in the 7.5m to 11m range.

Thanks for this information, especially about the difference between 10m2 and 11m2 only being marginal. Cheers, I hope to try some lightwind gear soon enough and see if I can pull together to cash to invest!

Excellent post.

Hi Agrelon, are you seriously considering a Formula and 10-ish sail? I would think that the additional weight of XXXL gear would make it useless for your 54 kgs. In other words, you may plane in 8/9 Knts with a 75 cm wide board plus 8.5 m² sail and 7/8 Knts with anything bigger (twice more expensive) but where is fun?
