323 Engine Size
George, While I have not had the pleasure of a sea trial on the B323, I also took note of the smaller standard engine on this new vessel. On closer inspection of the specifications, you will note that the 323 is nearly 3000# lighter and 8" narrower in beam than the B331.We have a 1996 B321 and, for a breif momment, were considering a newer vessel. The B321 ,I believe, shares the same hull as the B331, and has the same engine (although older model). We find the Yanmar 28HP an excellent performer, seldom reguiring more than 2600-2800RPM to reach an acceptable and comfortable motoring speed of 6+ knots. Even with the addition of 110v alternator, there is no discernable difference in motoring performance. Bare in mind also that the B331 and the B321 share the same engines used in the 35' 36' and the 37' models.For better opinions on the subject, you might want to post your question on the Beneteau Owners Discussion List <beneteau@list.sailnet.net> The 18HP Yanmar may well be adequate on this vessel, only a sea trial will tell.In answer to your performance question, I would suspect that the B323 is a good performer with its 4'9" std. draft, reduced displacement, and narrower beam. I don't know how the prices compare between these models. I suspect that this would not be my choice as I am more concerned about cruise performance. If racing is your thing, the 323 might be a good choice as I suspect that light air performance is better than either the B331 or the older B321.We were actually considering the B373, but did not see $100,000 worth of differences when compared to our B321.If price is not a significant issue, I would look again at the B331. If price is an issue, I would look closely at the B321. There are a number of good ones on the market for considerably less than new. Same goes for B331s. You usually get lots of addons cheap with a used vessel. Jon McClain
