[PUP] PPM, Round Tails, Big Rudders

[Kevin Kearney]

Sometimes when eating out I think about desert first.

With this PPM discussion and its various side trips perhaps backing into the conversation might help. If given the choice of heading into a sea or taking a following sea I for one like the sea from behind-less pounding more speed. The design question is--- is how well the boat surfs with a round tail, narrow tail or squared tail?

The relative merits of swim platforms in following seas, the aft underwater profiles that make a boat semi-displacement vs displacement and the size of rudders.

Methinks that flattened aft hull help put a boat up on plane, that wide flat transomes help interior space but can lead to broaching, and that small rudders offer less control at slow speeds than larger rudders.
