I like the rig, meaning the modified Dutch Gaff. But as to the sailplan, were it me, I'd simply put on a bigger main, add a larger jib
or two, and call it good.
I get that they're likely trying to keep the mast
about the same length as the boat
, but in light air, they'll be hurting for square footage of canvas
me thinks. Or is that not the curse of most Wharrams?
