A Class of One? I had a hard time making comparisons with the 3500 Sovran, primarily because of its wide beam. Although there are plenty of other cruisers with nominally similar LOAs, most either displaced less-displacement's a great way to compare interior volumes-or carried less beam. They're smaller boats, despite their length-based model designations. So look at Formula's 37 Performance Cruiser ($518,550, powered like my test boat). It posts identical performance, in addition to having a larger swim platform and twin bow sunpads. It doesn't offer the hardtop and solid glass enclosure you get with the 3500 Sovran, so you'll have to deal with canvas.
You'll also want to demo Sea Ray's 340 Sundancer ($304,634 with twin 375-hp MerCruiser 496 MAG DTS Seacore Bravo Three gasoline stern drives). Gas stern drives? Versus diesel tractors? When I tested it, the 340 Sundancer adhered to Falvey's Rule at speeds between 24 and 36 mph. Economy drops off precipitously after that. But since you're not buying diesel engines, you save cash up front, effectively getting seasons' worth of higher fuel burn for free. The 340 Sundancer tops out at 46 mph, and it doesn't offer joystick docking. Nibral (nickel-bronze-aluminum) IPS drives are better suited to saltwater than aluminum stern drives. Interestingly, IPS for gas engines is just coming out. In fact, it's one the 3500 Sovran's power options (twin 375-hp, $334,000). A comparison test would be great. (Tiara? Sea Ray? Formula? Any takers?)
Until then, the 3500 Sovran's huge and delightful cabin, coupe helm enclosure, efficiency, and joystick docking convenience, all for a middle-of-the-road price, make it my top pick.
Extra Point: Accessories such as the generator controls, filters, and pumps are mounted on a false bulkhead in the engine compartment, making service and installation easier.
