Hi Redhead, I don't think the key issue is double-ender or not. Whether a boat
is a "slug" or not depends on a lot of design considerations. The transom shape is only one, I would say, small component to this. Hull
shape, sail area, sail plan, beam, keel
... all these things factor into how a boat sails
My double-ender is no slug. Depending on the point of sail, she'll give any boat a run for their money
. On others, she ain't so great. Other double-enders have different characteristics. So like most sailing questions, the real answer is: it depends.
