I think that for a cruiser and for relaxed sailing the arch and the main sheet up there is an excellent idea. Dependng on the winds. The arch would not be a deal breaker for me.
I admit that some of the Hunters are not my favorite silhouette, but I would still have one if I had to.
My only "problem" if I can call that, as I see it, is the fact that the higher the main sheet travel is from the "ground", the longer the arm to the boat's center of gravity and midship
line.
As we all know, when the wind picks up, moving the traveller to leeward, reduces heel because of wind spill at the sail, BUT ALSO because the traveller is pulling the boat bellow the center
line and the heel reduces.
If you pull the travveler to windward it pulls the boat on the "high" side and heel gets worse.
That is the only real "technical" reason I see it a "problem", but a mild one at it.
I am all for inovative and off the box ideas.
I appologise for my english but the words fail me...was I understandable?
