The Itama 45RS 2023 vs Itama 50 2010 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 Itama 50 2010 measures 52,1 feet overall (2010), giving it roughly 6,7 additional feet of deck space compared to the Itama 45RS 2023 at 45,4 feet (2023). Weight tells a clearer story for trailering families: the Itama 50 2010 tips the scales at 56 460 lbs — 29 564 lbs less than the Itama 45RS 2023 at 26 896 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 800 hp, the Itama 50 2010 has a 250-hp advantage over the Itama 45RS 2023's 550-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Itama 45RS 2023 carries 859 gallons versus 660 gallons in the Itama 50 2010. 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 Itama 50 2010 is rated for 15 passengers, while the Itama 45RS 2023 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Itama 50 2010 could be the deciding factor.
Bottom line: Choose the Itama 50 2010 if your priority is putting more people on the water — it handles 15 passengers and at 52,1 ft it has the deck room to back that rating up comfortably. The Itama 45RS 2023 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
