Custom Line 120 2018 vs Custom Line Navetta 37 2023 — Same Brand, Different Boat

The Custom Line 120 2018 vs Custom Line Navetta 37 2023 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 120 2018 measures 125,1 feet overall (2018), giving it roughly 3,4 additional feet of deck space compared to the Custom Line Navetta 37 2023 at 121,7 feet (2023). Weight tells a clearer story for trailering families: the Custom Line 120 2018 tips the scales at 341 717 lbs — 300 932 lbs more than the Custom Line Navetta 37 2023 at 40 785 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 2 638 hp, the Custom Line 120 2018 has a 988-hp advantage over the Custom Line Navetta 37 2023's 1 650-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The Custom Line 120 2018 is rated for 38 passengers, while the Custom Line Navetta 37 2023 caps at 37. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Custom Line 120 2018 could be the deciding factor.

Bottom line: Choose the Custom Line 120 2018 if your priority is putting more people on the water — it handles 38 passengers and at 125,1 ft it has the deck room to back that rating up comfortably. The Custom Line Navetta 37 2023 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 37 that costs less to run day-to-day.

Custom Line 120 2018 vs Custom Line Navetta 37 2023 — Common Questions

Which is the larger boat — the Custom Line 120 2018 or the Custom Line Navetta 37 2023?
The Custom Line 120 2018 is the longer of the two at 125,1 feet overall. The Custom Line Navetta 37 2023 comes in at 121,7 feet, making it roughly 3,4 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 Navetta 37 2023?
For trailering, the Custom Line Navetta 37 2023 has the edge at 40 785 lbs dry weight versus 341 717 lbs for the Custom Line 120 2018. 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 Custom Line 120 2018 is rated to a maximum of 2 638 hp, giving it the larger power ceiling. The Custom Line Navetta 37 2023 tops out at 1 650 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 Custom Line 120 2018 is Coast Guard rated for 38 passengers, while the Custom Line Navetta 37 2023 is certified for 37. 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 Navetta 37 2023 measures 316" 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.
Are the Custom Line 120 2018 and Custom Line Navetta 37 2023 from the same manufacturer?
Yes — both the Custom Line 120 2018 and the Custom Line Navetta 37 2023 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.
