The Amels Avanti 2021 vs Amels Sixth Sense 2019 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 - Amels Avanti 2021 at 242,0 ft versus Amels Sixth Sense 2019 at 242,0 ft. Weight tells a clearer story for trailering families: the Amels Avanti 2021 tips the scales at 3 580 000 lbs - 6 000 lbs more than the Amels Sixth Sense 2019 at 3 574 000 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 2 855 hp, the Amels Avanti 2021 has a 136-hp advantage over the Amels Sixth Sense 2019's 2 719-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Amels Avanti 2021 carries 46 230 gallons versus 40 946 gallons in the Amels Sixth Sense 2019. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 73 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 Amels Avanti 2021 and its 2 855-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Amels Sixth Sense 2019 with its 2 719-hp rating is the more economical daily driver.
