The Princess Yachts 56 2016 vs Princess Yachts S65 Flybridge 2018 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 Princess Yachts S65 Flybridge 2018 measures 67,7 feet overall (2018), giving it roughly 8,2 additional feet of deck space compared to the Princess Yachts 56 2016 at 59,5 feet (2016). Weight tells a clearer story for trailering families: the Princess Yachts S65 Flybridge 2018 tips the scales at 82 100 lbs — 27 867 lbs less than the Princess Yachts 56 2016 at 54 233 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 1 400 hp, the Princess Yachts S65 Flybridge 2018 has a 600-hp advantage over the Princess Yachts 56 2016's 800-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Princess Yachts S65 Flybridge 2018 carries 108 gallons versus 7 gallons in the Princess Yachts 56 2016. 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 Princess Yachts S65 Flybridge 2018 is rated for 20 passengers, while the Princess Yachts 56 2016 caps at 18. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princess Yachts S65 Flybridge 2018 could be the deciding factor.
Bottom line: Choose the Princess Yachts S65 Flybridge 2018 if your priority is putting more people on the water — it handles 20 passengers and at 67,7 ft it has the deck room to back that rating up comfortably. The Princess Yachts 56 2016 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 18 that costs less to run day-to-day.
