The Custom Line 120 2018 vs Custom Line Navetta 50 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 Navetta 50 2023 measures 163,9 feet overall (2023), giving it roughly 38,8 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 Navetta 50 2023 tips the scales at 947 988 lbs — 606 271 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.
The power gap is worth calling out. Rated to 2 638 hp, the Custom Line 120 2018 has a 1 168-hp advantage over the Custom Line Navetta 50 2023's 1 470-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Custom Line Navetta 50 2023 carries 15 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 Navetta 50 2023 is rated for 49 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 Navetta 50 2023 could be the deciding factor.
Bottom line: Choose the Custom Line Navetta 50 2023 if your priority is putting more people on the water — it handles 49 passengers and at 163,9 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.
