Beauty is in the eye of the beholder. I agree with Gillie...of course any one that has a 21 I would have to agree with
My knock on the original design is that I think there is a big waste of space on to forward part of the boat. Those forward area's in front of the seats seem like an after thought. IMO that boat would be more functional as a cutty.
The second thing my opinion only, this is not dual purpose boat. If you want to make it look fast, then design the inside for fast cruising. I think Potter wanted both but did not accomplish it.
What you want to do with the boat is completely different than what the boat was build for. With that in mind I am totally confident it will be a Neat Strick designed boat, for whatever you have in mind.
