The Quintrex 510 Hornet 2023 vs Quintrex 520 Ocean Spirit 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 510 Hornet 2023 at 17,5 ft versus Quintrex 520 Ocean Spirit 2023 at 18,1 ft. Weight tells a clearer story for trailering families: the Quintrex 520 Ocean Spirit 2023 tips the scales at 1 481 lbs — 203 lbs less than the Quintrex 510 Hornet 2023 at 1 278 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 140 hp, the Quintrex 510 Hornet 2023 has a 25-hp advantage over the Quintrex 520 Ocean Spirit 2023's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Quintrex 510 Hornet 2023 and its 140-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Quintrex 520 Ocean Spirit 2023 with its 115-hp rating is the more economical daily driver.
