When two boats share the same hull type — in this case both the Arima Sea Hunter 15 Fish On 2010 and the Arima Sea Pacer 21 2013 are modified vee designs with fiberglass 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 Arima Sea Pacer 21 2013 measures 21,2 feet overall (2013), giving it roughly 6,6 additional feet of deck space compared to the Arima Sea Hunter 15 Fish On 2010 at 14,6 feet (2010). Weight tells a clearer story for trailering families: the Arima Sea Pacer 21 2013 tips the scales at 215 lbs — 123 lbs less than the Arima Sea Hunter 15 Fish On 2010 at 92 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 Arima Sea Hunter 15 Fish On 2010 carries a rated maximum of 80 hp. Engine data for the Arima Sea Pacer 21 2013 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.
For family outings this is probably the sharpest distinction between the two. The Arima Sea Pacer 21 2013 is rated for 6 passengers, while the Arima Sea Hunter 15 Fish On 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Arima Sea Pacer 21 2013 could be the deciding factor.
Bottom line: Choose the Arima Sea Pacer 21 2013 if your priority is putting more people on the water — it handles 6 passengers and at 21,2 ft it has the deck room to back that rating up comfortably. The Arima Sea Hunter 15 Fish On 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
