Matching a flat SeaArk 1648FN Flat Nose Jon 2013 against a modified vee SeaArk BayMaster 2010 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 BayMaster 2010 measures 20,1 feet overall (2010), giving it roughly 4,1 additional feet of deck space compared to the SeaArk 1648FN Flat Nose Jon 2013 at 16,0 feet (2013). Weight tells a clearer story for trailering families: the SeaArk BayMaster 2010 tips the scales at 1 325 lbs — 970 lbs less than the SeaArk 1648FN Flat Nose Jon 2013 at 355 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 150 hp, the SeaArk BayMaster 2010 has a 125-hp advantage over the SeaArk 1648FN Flat Nose Jon 2013's 25-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 BayMaster 2010 is rated for 10 passengers, while the SeaArk 1648FN Flat Nose Jon 2013 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk BayMaster 2010 could be the deciding factor.
Bottom line: Choose the SeaArk BayMaster 2010 if your priority is putting more people on the water — it handles 10 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk 1648FN Flat Nose Jon 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
