The Sealine F42 2012 vs Sealine T50 2006 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 Sealine T50 2006 measures 50,7 feet overall (2006), giving it roughly 8,3 additional feet of deck space compared to the Sealine F42 2012 at 42,4 feet (2012). Weight tells a clearer story for trailering families: the Sealine F42 2012 tips the scales at 51 854 lbs — 9 967 lbs more than the Sealine T50 2006 at 41 887 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 600 hp, the Sealine F42 2012 has a 25-hp advantage over the Sealine T50 2006's 575-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sealine T50 2006 carries 558 gallons versus 317 gallons in the Sealine F42 2012. 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 Sealine T50 2006 is rated for 15 passengers, while the Sealine F42 2012 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sealine T50 2006 could be the deciding factor.
Bottom line: Choose the Sealine T50 2006 if your priority is putting more people on the water — it handles 15 passengers and at 50,7 ft it has the deck room to back that rating up comfortably. The Sealine F42 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
