Hi Gyurmo,
Alena (In Boston, MA, USA) is a lightweight woman doctor (MD).
On the one hand we are telling her to use a 10 m2 rig (how she gets a 10 out if the water at her size is almost beyond my comprehension) then we tell her she might be better off with cambered sails,
right after a thread where we suggest that free race sails might give better low wind power.
We might be confusing her?
