The Fairline Squadron 78 2015 vs Fairline Targa 48 GT 2019 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 Fairline Squadron 78 2015 measures 79,1 feet overall (2015), giving it roughly 28,3 additional feet of deck space compared to the Fairline Targa 48 GT 2019 at 50,8 feet (2019). Weight tells a clearer story for trailering families: the Fairline Squadron 78 2015 tips the scales at 121 254 lbs — 91 492 lbs more than the Fairline Targa 48 GT 2019 at 29 762 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 1 600 hp, the Fairline Squadron 78 2015 has a 720-hp advantage over the Fairline Targa 48 GT 2019's 880-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Fairline Squadron 78 2015 carries 1 320 gallons versus 288 gallons in the Fairline Targa 48 GT 2019. 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 Fairline Squadron 78 2015 is rated for 24 passengers, while the Fairline Targa 48 GT 2019 caps at 15. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fairline Squadron 78 2015 could be the deciding factor.
Bottom line: Choose the Fairline Squadron 78 2015 if your priority is putting more people on the water — it handles 24 passengers and at 79,1 ft it has the deck room to back that rating up comfortably. The Fairline Targa 48 GT 2019 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 15 that costs less to run day-to-day.
