When two boats share the same hull type — in this case both the SeaArk 1860MVJT 2009 and the SeaArk BayFisher MVT 2013 are tunnel designs with aluminum 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?
On paper these two are close siblings in the size department — SeaArk 1860MVJT 2009 at 18,0 ft versus SeaArk BayFisher MVT 2013 at 20,1 ft. Weight tells a clearer story for trailering families: the SeaArk BayFisher MVT 2013 tips the scales at 119 lbs — 114 lbs less than the SeaArk 1860MVJT 2009 at 5 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 140 hp, the SeaArk BayFisher MVT 2013 has a 75-hp advantage over the SeaArk 1860MVJT 2009's 65-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 6 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: The SeaArk BayFisher MVT 2013 at 20,1 ft is the right call if deck space, comfort, and entertaining are top of your list. The SeaArk 1860MVJT 2009 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
