The Fountaine Pajot MY4.S 2023 vs Fountaine Pajot Thirra 80 2024 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 Thirra 80 2024 measures 78,7 feet overall (2024), giving it roughly 42,6 additional feet of deck space compared to the Fountaine Pajot MY4.S 2023 at 36,1 feet (2023). Weight tells a clearer story for trailering families: the Fountaine Pajot Thirra 80 2024 tips the scales at 145 505 lbs — 124 562 lbs less than the Fountaine Pajot MY4.S 2023 at 20 943 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 300 hp, the Fountaine Pajot Thirra 80 2024 has a 50-hp advantage over the Fountaine Pajot MY4.S 2023's 250-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 Thirra 80 2024 carries 634 gallons versus 316 gallons in the Fountaine Pajot MY4.S 2023. 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 Thirra 80 2024 is rated for 23 passengers, while the Fountaine Pajot MY4.S 2023 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 Thirra 80 2024 could be the deciding factor.

Displacement is where these two sailboats genuinely part ways. The Fountaine Pajot Thirra 80 2024 displaces 145 505 lbs — a 124 562-lb difference over the Fountaine Pajot MY4.S 2023 at 20 943 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 Thirra 80 2024 draws 6,9 ft, compared to 2,6 ft for the Fountaine Pajot MY4.S 2023. That 4,3-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 Thirra 80 2024 carries a 300-hp engine against 250 hp on the Fountaine Pajot MY4.S 2023. 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 Thirra 80 2024 carries 423 gallons versus 92 gallons on the Fountaine Pajot MY4.S 2023 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.
