AB Yachts 120 2023 vs AB Yachts 787 2024 — Same Brand, Different Boat

The AB Yachts 120 2023 vs AB Yachts 787 2024 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 AB Yachts 120 2023 measures 121,1 feet overall (2023), giving it roughly 39,3 additional feet of deck space compared to the AB Yachts 787 2024 at 81,8 feet (2024). Weight tells a clearer story for trailering families: the AB Yachts 120 2023 tips the scales at 297 624 lbs — 121 255 lbs more than the AB Yachts 787 2024 at 176 369 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 2 600 hp, the AB Yachts 120 2023 has a 600-hp advantage over the AB Yachts 787 2024's 2 000-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the AB Yachts 120 2023 carries 4 095 gallons versus 2 483 gallons in the AB Yachts 787 2024. 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 AB Yachts 120 2023 is rated for 36 passengers, while the AB Yachts 787 2024 caps at 24. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Yachts 120 2023 could be the deciding factor.

Bottom line: Choose the AB Yachts 120 2023 if your priority is putting more people on the water — it handles 36 passengers and at 121,1 ft it has the deck room to back that rating up comfortably. The AB Yachts 787 2024 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 24 that costs less to run day-to-day.

The AB Yachts 120 2023 is the longer of the two at 121,1 feet overall. The AB Yachts 787 2024 comes in at 81,8 feet, making it roughly 39,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the AB Yachts 120 2023 or the AB Yachts 787 2024?
For trailering, the AB Yachts 787 2024 has the edge at 176 369 lbs dry weight versus 297 624 lbs for the AB Yachts 120 2023. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The AB Yachts 120 2023 is rated to a maximum of 2 600 hp, giving it the larger power ceiling. The AB Yachts 787 2024 tops out at 2 000 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The AB Yachts 120 2023 is Coast Guard rated for 36 passengers, while the AB Yachts 787 2024 is certified for 24. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The AB Yachts 120 2023 measures 296" wide, compared to 257" for the AB Yachts 787 2024. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.

The AB Yachts 120 2023 has the bigger tank at 4 095 gallons, versus 2 483 gallons on the AB Yachts 787 2024. That 1612-gallon difference translates to roughly 4836–8060 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
