When two boats share the same hull type — in this case both the Carver Yachts 36 Mariner 2008 and the Carver Yachts 46 Motor Yacht 2009 are modified vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Carver Yachts 46 Motor Yacht 2009 measures 49,0 feet overall (2009), giving it roughly 13,0 additional feet of deck space compared to the Carver Yachts 36 Mariner 2008 at 36,0 feet (2008). Weight tells a clearer story for trailering families: the Carver Yachts 46 Motor Yacht 2009 tips the scales at 435 lbs — 240 lbs less than the Carver Yachts 36 Mariner 2008 at 195 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 575 hp, the Carver Yachts 46 Motor Yacht 2009 has a 200-hp advantage over the Carver Yachts 36 Mariner 2008's 375-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Carver Yachts 46 Motor Yacht 2009 carries 48 gallons versus 25 gallons in the Carver Yachts 36 Mariner 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
