For a semi displacement hull the Fleming is very efficient at displacement speeds because it doesn’t carry too much weight in the stern. As others have said, I think the lower CofG is a price worth paying with the low height of the engine room and if they put more modest engines in it wouldn’t be as big an issue. I know they fiddled with them a bit but keeping close to the original design helps when it comes to sorting snags. The main gripe I have heard about Flemings is from boat detailers who hate the moulded in grooves in the hull. If I had the money I would get a 58 with JDs in it. Unfortunately I don’t have have money.
