The Fountaine Pajot Auro 51 2020 vs Fountaine Pajot Lavezzi 40 2002 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 Fountaine Pajot Auro 51 2020 measures 51,0 feet overall (2020), giving it roughly 12,0 additional feet of deck space compared to the Fountaine Pajot Lavezzi 40 2002 at 39,0 feet (2002). Weight tells a clearer story for trailering families: the Fountaine Pajot Auro 51 2020 tips the scales at 39 903 lbs — 26 234 lbs more than the Fountaine Pajot Lavezzi 40 2002 at 13 669 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 75 hp, the Fountaine Pajot Auro 51 2020 has a 57-hp advantage over the Fountaine Pajot Lavezzi 40 2002's 18-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Fountaine Pajot Auro 51 2020 carries 236 gallons versus 66 gallons in the Fountaine Pajot Lavezzi 40 2002. 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 Fountaine Pajot Auro 51 2020 is rated for 15 passengers, while the Fountaine Pajot Lavezzi 40 2002 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Fountaine Pajot Auro 51 2020 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Fountaine Pajot Auro 51 2020 displaces 39 903 lbs — a 26 234-lb difference over the Fountaine Pajot Lavezzi 40 2002 at 13 669 lbs. That gap separates two entirely different categories of sailing: the heavier boat is built for offshore passage-making and load-carrying, while the lighter hull rewards performance sailing and easier handling in lighter air.

Draft is a practical consideration that many buyers underestimate until they're already at the marina. The Fountaine Pajot Auro 51 2020 draws 5,2 ft, compared to 3,7 ft for the Fountaine Pajot Lavezzi 40 2002. That 1,5-foot difference affects which anchorages you can access, which haul-out facilities will take you, and how carefully you need to read the tide tables in shallower cruising grounds.

For auxiliary power the Fountaine Pajot Auro 51 2020 carries a 75-hp engine against 18 hp on the Fountaine Pajot Lavezzi 40 2002. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

For extended cruising, water capacity matters: the Fountaine Pajot Auro 51 2020 carries 237 gallons versus 147 gallons on the Fountaine Pajot Lavezzi 40 2002 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
