When two boats share the same hull type — in this case both the Frontier Boats 190 2009 and the Frontier Boats Frontier Open Series 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?
On paper these two are close siblings in the size department — Frontier Boats 190 2009 at 19,0 ft versus Frontier Boats Frontier Open Series 2013 at 18,2 ft. At 12 lbs and 11 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 Frontier Boats 190 2009 has a 35-hp advantage over the Frontier Boats Frontier Open Series 2013's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Frontier Boats 190 2009 carries 43 gallons versus 22 gallons in the Frontier Boats Frontier Open Series 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Frontier Boats Frontier Open Series 2013 is rated for 6 passengers, while the Frontier Boats 190 2009 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Frontier Boats Frontier Open Series 2013 could be the deciding factor.
Bottom line: Choose the Frontier Boats Frontier Open Series 2013 if your priority is putting more people on the water — it handles 6 passengers and at 18,2 ft it has the deck room to back that rating up comfortably. The Frontier Boats 190 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
