Headline - LIGHTWIND. If we can talk in m/s it is easyer for me.
How well does JP SLW work in different lightwind conditions with me, 78 kg?
5 m/s - SLW plans and works great with 9.0
5-6 m/s - SLW plans and works great with 7.5
7-8 m/s - SLW plans and works great with 6.5
8-10 m/s - SLW plans and works great with 5.5
Off course You can use bigger sails up to 10 m/s but if You want a pleasant ride I mean that it is possible to sail a wide board with smaller sails. As an example I hade 27 knots with SLW and an old non camberad 6.5 sail.
If we are talking about Formula sails, 10-12, - Why do´t we talk about Formula boards? I thought we were talking about lightwind using hybrid boards or wide slalomboards. After some years with SLW I can not see the problems using smaller sails in higher windrange (within lightwind conditions)!
