When two boats share the same hull type — in this case both the SeaArk 2072 Pro 2012 and the SeaArk BaySport 2009 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 2072 Pro 2012 measures 20,1 feet overall (2012), giving it roughly 18,1 additional feet of deck space compared to the SeaArk BaySport 2009 at 2,0 feet (2009). At 95 lbs and 147 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 140 hp for the SeaArk 2072 Pro 2012 and 150 hp for the SeaArk BaySport 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.
For family outings this is probably the sharpest distinction between the two. The SeaArk BaySport 2009 is rated for 8 passengers, while the SeaArk 2072 Pro 2012 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the SeaArk BaySport 2009 could be the deciding factor.
Bottom line: Choose the SeaArk BaySport 2009 if your priority is putting more people on the water — it handles 8 passengers and at 2,0 ft it has the deck room to back that rating up comfortably. The SeaArk 2072 Pro 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 6 that costs less to run day-to-day.
