The Quintrex 390 Explorer 2017 vs Quintrex 450 Fishaboat 2023 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

On paper these two are close siblings in the size department — Quintrex 390 Explorer 2017 at 12,9 ft versus Quintrex 450 Fishaboat 2023 at 15,6 ft. Weight tells a clearer story for trailering families: the Quintrex 450 Fishaboat 2023 tips the scales at 992 lbs — 769 lbs less than the Quintrex 390 Explorer 2017 at 223 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 75 hp, the Quintrex 450 Fishaboat 2023 has a 45-hp advantage over the Quintrex 390 Explorer 2017's 30-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 Quintrex 450 Fishaboat 2023 is rated for 4 passengers, while the Quintrex 390 Explorer 2017 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Quintrex 450 Fishaboat 2023 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The Quintrex 390 Explorer 2017 comes in at 7 lbs per hp versus 13 lbs per hp for the Quintrex 450 Fishaboat 2023. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.

Both the Quintrex 390 Explorer 2017 and Quintrex 450 Fishaboat 2023 are trailerable, which is a big part of the appeal at this size. You can store either at home, hitch up on a whim, and launch wherever the water looks good.
