As fiberglass1 stated, draft varies on these models. Others made some excellent points as well.
I've been doing some serious boat shopping over the last 7 months, looked at lots of racer/cruisers under 50K.
First thing that should be decided is if draft is a factor. They may have produced shoal or c/b models, but, how prevalent are they in the market?
At first I was a little scared of boats cored below the waterline. Talks with good surveyors got me down off that ledge as long as you don't gamble by not getting a full survey or buying a boat of unknown quality of production.
I owned a 30 MKI for a decade. It's very roomy for a boat of that size and vintage. For less than 25K you can find one in really good shape.
I'm in a purchase agreement for a 30 MKII, it's also very roomy for it's vintage. Decent head room and an "aft cabin". I feel that I've gone up a size but it will be just as easy to handle and my yard rates will be the same. I looked at almost every one for sale in the USA, I'll post more on that after I close.
The sticker shock I found was boat transport (don't forget the yard fees on either end). Holy crap! For a 30 ft boat it can easily run up to 3K+ for a 6 hour drive. I might end up sailing mine simply because I'm running out of boat bucks
