They aren't quite so AR regarding length as they were, Skipper. Right now there's no problem with C320's and Bene 323's in 30 foot slips, if the slip is wide enough. I used to have mine in a 30' slip that was 1 inch wider than the beam. If it's got a bowsprit something like a PSC 31, Orion 27 or NorSea 27 is the length that will fit in 30'. An IP 320 or PSC 34 needs to go in a 35.
If you want a Bristol you might have to bring that one with you, market is very low right now, all the brokers are scrambling for listings.
