A true Chincoteague scow will take you thru rough water that a garvey hull won,t handle due to the rake on bottom. The best of them weren't flat bottom as those Garvey's are. Never seen any scows built as small as 10' but have seen a few 12',s. Hull shape whether Chinc. Scow or Garvey will be a wet ride in rough seas but that little 10' in ad was probably made for not much more than where one would use a pond bx. When our eastern shore scows were planked bottoms they were flat similar to garvey. But these weren't Chincoteague scows. They didn,t get that name till plywood started being used by the Hancock,s & Jesters, the best builders of the "Chincoteague Scow". A few Fiberglass boats were patterned from those hulls. The defunct Glass Boat Works Scow & a couple others. Sweet hulls which would take you there & back but better have on a rain jkt. doing it if rough. Those hulls tended to throw spray over about last 3' of hull if rough, especially quartering.
