Meridian claims that the 441 tops out at over 33 mph with the larger 474-bhp Cummins MerCruiser diesels installed. My tester's twin 420-bhp QSB 5.9s delivered 30.1 mph at full throttle with four people aboard, the optional hardtop (price n/a at press time) installed, its bottom painted, and fully laden. I wouldn't want more horsepower. The 441 planed readily -- in fact, with less inclination than what I've experienced aboard many pod-powered boats. I'd attribute this to the down-angle thrust delivered by conventional props and shafts. (Note: This same feature is largely what diminishes efficiency and speed once on plane compared to the "flat" shaft angle of pods.) At 22 mph, the engines burned 33.4 gph, producing 0.6 mpg for a range of 257 miles. It held plane at 11 mph, identical to the minimum planing speed I recorded during my test of Silverton's 43 Sportbridge ($654,078 with twin 435-bhp Volvo Penta IPS 600 tractor drives and joystick). That's a great attribute when the wind comes up in your face and you want to proceed in control but without dropping off the crests of waves and slamming. These speeds, though slower than boats powered by pods or express boats of any ilk, are acceptable to me. Why? Because a sedan such as the 441 is about the destination, rather than a means to a destination.
