There is no easy answer here because almost any boat will pound in the right conditions. The worst boats when it comes to pounding are older IOR era boats from the 1970's through mid- 1980's. These boats typically have a hull that when seen in section have three flats and those flats will really slap the surface.
Older cca era designs with vee shapes in section (such as the Southern Cross 31, Hallberg-Rassy Monsun 31, Golden Hind 31, Elizabethan 31 mentioned above) tend to have full ends and so will colide with each wave, and tend to sail heeled further over and so will pound on their topsides as well.
In my experience least amount of impact with waves occurs in some of the early IMS boats which had very fine entries and long waterlines and some flare to the topsides.
