Matching a tunnel SeaArk 1660 MVT Rescue 2011 against a modified vee SeaArk ProCat 240 2009 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 SeaArk ProCat 240 2009 measures 24,0 feet overall (2009), giving it roughly 8,0 additional feet of deck space compared to the SeaArk 1660 MVT Rescue 2011 at 16,0 feet (2011). Weight tells a clearer story for trailering families: the SeaArk ProCat 240 2009 tips the scales at 172 lbs — 110 lbs less than the SeaArk 1660 MVT Rescue 2011 at 62 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 225 hp, the SeaArk ProCat 240 2009 has a 175-hp advantage over the SeaArk 1660 MVT Rescue 2011's 50-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 SeaArk ProCat 240 2009 is rated for 10 passengers, while the SeaArk 1660 MVT Rescue 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk ProCat 240 2009 could be the deciding factor.
Bottom line: Choose the SeaArk ProCat 240 2009 if your priority is putting more people on the water — it handles 10 passengers and at 24,0 ft it has the deck room to back that rating up comfortably. The SeaArk 1660 MVT Rescue 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
