As far as I know, the only rig difference is that BD has a stiffer
mast. BD is/was considerably lighter (2 and a bit tons vs 3 and a
bit), has less windage and a rockered ww hull. My guess is that once
the sailmaker has a look and the crew gains some
experience/confidence, the speeds will increase dramatically.

> So, how to explain the difference between the two ships in their original configuration? Can the weight difference explain that much? Were Rare Bird's rudders stronger originally? What is the difference in the rig as Rare Bird is not contemplating a change ?
