Well.... the Hog is right about one thing - The Madness
I assume you have looked into pricing of a newer and larger Nauticat. If not be prepared for some serious sticker shock
..... and because of that, newer Nauticats are few and far between. I bought my 99 331 almost 2 years ago and in that 2 years have not seen another 331 (started in 98 as a change from the 33) on Yachtworld or anywhere else in this country. When the Euro beat the crap out of the $ the US market died. As for Hog's comments on a Catalina.... I had 2 of them and traded in a 99 c320 for a 99 NC331 at 3 times the price - hence The Madness

Not trying to scare you away or impress you with my penchant for spending money (that I don't have) but if I had enough money to even consider a newer, much larger Nauticat, I would fly to Finland, talk to Mr Gustoffson, and have them build me one - that's what they love to do as a semi-custom operation.
