Yes, the DNA is sure easy to see between the three brands. The changes to the Jupiter are subtle and evoluntionary, here are a couple of comparative pics:
34' Venture
34' Jupiter
The main difference is the bow is much fuller, and the gunnels somewhat higher in the new Jupiter, this is to accomodate the cuddy cabin model that will be launched at Miami. Also, you can see the Jupiter now carries a bit more beam than the Venture, it's about 10'3" at the W/L, 10'7" at the gunnel.
This full bow is also seen in the 31' Bahama:
It seems the trend is to widen the bow, push the beam out, and extend the running surfaces by shortening the amount of notch allowed for the transom step. My guess is the Jupiter has the extended aft running surfaces as well.
Compare this "old school" transom notch from the 38' Jupiter, with the previous Bahama 31' notches:
Before I rode the Bahama 31', I would have bet against that 11' beam working out in a head sea, but boy , was I wrong. Best non-stepped hull I've ever been on.
Wonder how the Jupiter 34' will work out.....
