The 310 and the 330 were in Norwalk this past weekend and will be at Tobay this week. The Odd numbered series usually correspond to the newer designs from 2007/2008. I think eventually you'll see a 350 when the 340 is retired.
Although I'm relatively new in the business (2months), I've driven all of these boats and a few others. The 310 (IMHO) is no dog. She cruises nicely at 28-29 knots. The 340 is a beast! with T-8.1's she runs 30-32Knots at about 80% of WOT. At 3500 RPM you'll cruise 28-29 Knots no problem.
As for when is the "right" time to buy for the "best" deal....If your looking at SR your most likely talking to MM (HZO). Their fiscal year runs same as Calendar year which puts Q3 close at Sept 30th.
With the current state of the economy and housing market, it's no secret 2007 has been a tough year for any company selling luxury items. Also, most car dealers (and probably boat dealers) have existing inventory that they classify as "Floor Plan" meaning they pay little or no interest on the inventory (MFG pays) until an agreed upon time in the future. Often, this expires when the new Model year becomes available. Quite often this is September.
SO, because all public companies discount to make QTR end numbers, and the whole floor plan scenario, I'd say now is a better time to buy than NY boat show or any other time.
If MM (HZO) misses Q3, they will most likely say F'it, we missed Q3 anyway, might as well lower guidance for FY08 and keep margins up.
Its been many years since a public boat dealer has been in this predicament. The boating industry has enjoyed YOY sales growth of 10-20% the past few years. Wall Street rewards growth and punishes flat or declining revenue. Right now its all about revenue for MM (IMHO) and margins are secondary.
If your buying a boat soon from MM I would not wait until the second weekend of Tobay (Oct.) to do so. By then it's too late for them. Additionally, they were telling people at Norwalk the SR incentives are up on Sept 30th. Coincidence?
We'll see.
