The Fairline Squadron 78 2015 vs Fairline Squadron 78 Custom 2007 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 71,1 additional feet of deck space compared to the Fairline Squadron 78 Custom 2007 at 8,0 feet (2007). Weight tells a clearer story for trailering families: the Fairline Squadron 78 2015 tips the scales at 121 254 lbs — 120 235 lbs more than the Fairline Squadron 78 Custom 2007 at 1 019 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 3 058 hp, the Fairline Squadron 78 Custom 2007 has a 1 458-hp advantage over the Fairline Squadron 78 2015's 1 600-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 Custom 2007 carries 1 556 gallons versus 1 320 gallons in the Fairline Squadron 78 2015. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 24 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
