The Amels Altair III 1974 vs Amels Amigos 2017 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.
Size is the most obvious dividing line here. The Amels Altair III 1974 measures 194,0 feet overall (1974), giving it roughly 14,0 additional feet of deck space compared to the Amels Amigos 2017 at 180,0 feet (2017). Weight tells a clearer story for trailering families: the Amels Altair III 1974 tips the scales at 1 734 000 lbs — 394 000 lbs more than the Amels Amigos 2017 at 1 340 000 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 1 408 hp, the Amels Amigos 2017 has a 783-hp advantage over the Amels Altair III 1974's 625-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 Altair III 1974 carries 34 342 gallons versus 30 379 gallons in the Amels Amigos 2017. 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 Amels Altair III 1974 is rated for 59 passengers, while the Amels Amigos 2017 caps at 54. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Amels Altair III 1974 could be the deciding factor.
Bottom line: Choose the Amels Altair III 1974 if your priority is putting more people on the water — it handles 59 passengers and at 194,0 ft it has the deck room to back that rating up comfortably. The Amels Amigos 2017 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 54 that costs less to run day-to-day.
