When two boats share the same hull type — in this case both the SeaArk BayFisher 2012 and the SeaArk Forecast 156 2011 are modified vee 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?
Size is the most obvious dividing line here. The SeaArk BayFisher 2012 measures 20,1 feet overall (2012), giving it roughly 4,6 additional feet of deck space compared to the SeaArk Forecast 156 2011 at 15,5 feet (2011). Weight tells a clearer story for trailering families: the SeaArk BayFisher 2012 tips the scales at 119 lbs — 112 lbs more than the SeaArk Forecast 156 2011 at 7 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 2012 has a 100-hp advantage over the SeaArk Forecast 156 2011'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 SeaArk BayFisher 2012 is rated for 6 passengers, while the SeaArk Forecast 156 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk BayFisher 2012 could be the deciding factor.
Bottom line: Choose the SeaArk BayFisher 2012 if your priority is putting more people on the water — it handles 6 passengers and at 20,1 ft it has the deck room to back that rating up comfortably. The SeaArk Forecast 156 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
