Matching a inflatable rigid Mercury PT850 2008 against a inflatable non rigid Mercury V-400 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
Size is the most obvious dividing line here. The Mercury PT850 2008 measures 27,0 feet overall (2008), giving it roughly 14,0 additional feet of deck space compared to the Mercury V-400 2008 at 13,0 feet (2008). Weight tells a clearer story for trailering families: the Mercury PT850 2008 tips the scales at 2 557 lbs — 2 244 lbs more than the Mercury V-400 2008 at 313 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 500 hp, the Mercury PT850 2008 has a 460-hp advantage over the Mercury V-400 2008's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Mercury PT850 2008 is rated for 26 passengers, while the Mercury V-400 2008 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Mercury PT850 2008 could be the deciding factor.
Bottom line: Choose the Mercury PT850 2008 if your priority is putting more people on the water — it handles 26 passengers and at 27,0 ft it has the deck room to back that rating up comfortably. The Mercury V-400 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
