Princess Yachts 64 2011 vs Princess Yachts S66 2020 — Same Brand, Different Boat

The Princess Yachts 64 2011 vs Princess Yachts S66 2020 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.

The power gap is worth calling out. Rated to 1 200 hp, the Princess Yachts S66 2020 has a 50-hp advantage over the Princess Yachts 64 2011's 1 150-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 S66 2020 carries 902 gallons versus 9 gallons in the Princess Yachts 64 2011. 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 S66 2020 is rated for 20 passengers, while the Princess Yachts 64 2011 caps at 19. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Princess Yachts S66 2020 could be the deciding factor.

Bottom line: Choose the Princess Yachts S66 2020 if your priority is putting more people on the water — it handles 20 passengers and at 66,1 ft it has the deck room to back that rating up comfortably. The Princess Yachts 64 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 19 that costs less to run day-to-day.

How many people can each boat hold?
The Princess Yachts 64 2011 is Coast Guard rated for 19 passengers, while the Princess Yachts S66 2020 is certified for 20. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

The Princess Yachts S66 2020 measures 203" wide, compared to 197" for the Princess Yachts 64 2011. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
