Good point! I'll go with that. Lot's of nice scows but looks like that 30' would be the easiest. Guess will need to find a plan and this is primarily to be motored. Not sure what sail plan it could have, but actually needs to be smaller than those show, can't exceed 19' over the water. Many shown just don't have the room forward, the low cabins won't work either but that's something that can be adopted, I don't see that as a big deal.
As to the amas, again, should they be shaped as the main hull or pointy shaped, just thinking the scow look with a scow shaped ama might look consistent...?????
