Custom Line 120 2018 vs Custom Line 140 2022 — Same Brand, Different Boat

The Custom Line 120 2018 vs Custom Line 140 2022 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 Custom Line 140 2022 measures 139,1 feet overall (2022), giving it roughly 14,0 additional feet of deck space compared to the Custom Line 120 2018 at 125,1 feet (2018). Weight tells a clearer story for trailering families: the Custom Line 140 2022 tips the scales at 496 040 lbs — 154 323 lbs less than the Custom Line 120 2018 at 341 717 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.

Both boats share a closely matched power ceiling — 2 638 hp for the Custom Line 120 2018 and 2 638 hp for the Custom Line 140 2022. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Custom Line 140 2022 carries 8 gallons versus 4 gallons in the Custom Line 120 2018. 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 Custom Line 140 2022 is rated for 42 passengers, while the Custom Line 120 2018 caps at 38. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Custom Line 140 2022 could be the deciding factor.

Bottom line: Choose the Custom Line 140 2022 if your priority is putting more people on the water — it handles 42 passengers and at 139,1 ft it has the deck room to back that rating up comfortably. The Custom Line 120 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 38 that costs less to run day-to-day.

Custom Line 120 2018 vs Custom Line 140 2022 — Common Questions

Which is the larger boat — the Custom Line 120 2018 or the Custom Line 140 2022?
The Custom Line 140 2022 is the longer of the two at 139,1 feet overall. The Custom Line 120 2018 comes in at 125,1 feet, making it roughly 14,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Custom Line 120 2018 or the Custom Line 140 2022?
For trailering, the Custom Line 120 2018 has the edge at 341 717 lbs dry weight versus 496 040 lbs for the Custom Line 140 2022. 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.
How many people can each boat hold?
The Custom Line 120 2018 is Coast Guard rated for 38 passengers, while the Custom Line 140 2022 is certified for 42. 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 Custom Line 140 2022 measures 336" wide, compared to 301" for the Custom Line 120 2018. 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.
Which boat has the larger fuel tank — the Custom Line 120 2018 or the Custom Line 140 2022?
The Custom Line 140 2022 has the bigger tank at 8 gallons, versus 4 gallons on the Custom Line 120 2018. That 3-gallon difference translates to roughly 10–16 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Custom Line 120 2018 and Custom Line 140 2022 from the same manufacturer?
Yes — both the Custom Line 120 2018 and the Custom Line 140 2022 are built by Custom Line. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
