i built this boat from the free plan set out of the boat magazine, and she sailed well, thought about scaling her up to 1'24 th, then could add more detail etc, built the hull, but then put it aside as i started building 70 ft vosper mtb, one day get around to finshing the Miami crash boat off, looking at the myhobby store, i see they have 1/24 th scale plan, and its 21.5" long, shouldn't that be 31.5" long
