The Amels Haemony 2001 vs Amels Just B 1973 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 Just B 1973 measures 194,0 feet overall (1973), giving it roughly 24,0 additional feet of deck space compared to the Amels Haemony 2001 at 170,0 feet (2001). Weight tells a clearer story for trailering families: the Amels Just B 1973 tips the scales at 1 938 000 lbs — 690 000 lbs less than the Amels Haemony 2001 at 1 248 000 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 1 180 hp, the Amels Haemony 2001 has a 87-hp advantage over the Amels Just B 1973's 1 093-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 Just B 1973 carries 22 856 gallons versus 3 165 gallons in the Amels Haemony 2001. 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 Just B 1973 is rated for 59 passengers, while the Amels Haemony 2001 caps at 51. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Amels Just B 1973 could be the deciding factor.
Bottom line: Choose the Amels Just B 1973 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 Haemony 2001 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 51 that costs less to run day-to-day.
