When two boats share the same hull type — in this case both the Arima Sea Chaser 19 Fish On 2010 and the Arima Sea Hunter 15 Fish On 2012 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 Chaser 19 Fish On 2010 measures 18,9 feet overall (2010), giving it roughly 4,3 additional feet of deck space compared to the Arima Sea Hunter 15 Fish On 2012 at 14,6 feet (2012). At 16 lbs and 92 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.
The power gap is worth calling out. Rated to 150 hp, the Arima Sea Chaser 19 Fish On 2010 has a 70-hp advantage over the Arima Sea Hunter 15 Fish On 2012's 80-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 Arima Sea Chaser 19 Fish On 2010 is rated for 8 passengers, while the Arima Sea Hunter 15 Fish On 2012 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 Chaser 19 Fish On 2010 could be the deciding factor.
Bottom line: Choose the Arima Sea Chaser 19 Fish On 2010 if your priority is putting more people on the water — it handles 8 passengers and at 18,9 ft it has the deck room to back that rating up comfortably. The Arima Sea Hunter 15 Fish On 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
