Hi Mikael. 

Elvstrm defines the sweet spot for the Crossover Sail with 5-20kn True and 67-140 TWA. 
What's your experience with this sail? Would you say you can helm lower with this sail in more pressure?

Hello :)

My experience is roughly that of the Hanse graphic and the values you mention. More pressure will have some affect but at 140-145 TWA (depending on speed and AWA) the margins start to get thin, and at 150+ it collapses. I guess because it's shadowed by the main.

I haven't measured this very exactly though, so one more thing to add to the todo list :)
