Our Take

The FPY80S is Fountaine Pajot's most ambitious sailing catamaran to date, and it shows in the systems architecture. The lithium storage, solar generation and a desalination plant rated at up to 158 gallons an hour are not marketing features—they're designed to eliminate the constant generator cycling that plagues most boats this size. The build quality is consistent with what I've seen from the yard over the past decade: infused composite construction, conservative engineering, and a rig sized for serious passage-making at 80 feet. The 6'6" draft is a compromise, but it's the right one for the cruising grounds this boat will actually see.

This boat is for the experienced cruiser who has already owned a 50-60 foot catamaran and knows exactly what didn't work. It's not for the first-time buyer stepping up from a monohull. The systems are complex, the operating costs are real, and the learning curve is steep if you're planning to owner-operate. If you're chartering, the layout options and crew quarters make this one of the most flexible platforms in the 75-85 foot range. If you're an owner, you need to be honest about how many nights a year you'll actually be aboard, because that's what makes the economics work.

Resale will be strong in the charter market, softer in the private owner market. Fountaine Pajot has a loyal following, but the FPY80S is new enough that we don't have three-year depreciation data yet. Expect the steepest depreciation early, then a flattening curve—that's the pattern for new models at this size. Running costs are real: crew, rig, systems. Budget honestly for them before you fall in love with the layout. The boat will hold its value better than a comparable motor yacht, but it won't appreciate.

Fountaine Pajot FPY80S Overview

The FPY80S is the 80-foot sailing catamaran of Fountaine Pajot's yacht line. The sheet reads 78'8" overall on a 36'5" beam and 6'6" draft, with 634 gallons of fuel and 423 gallons of water.

The platform proved itself under its pre-2025 name, the Thira 80, including on the yard's own Monaco-to-Saint-Tropez sea trial — which is where the cruising figures below come from.

Performance & Handling

Fountaine Pajot's own sea trial of the platform recorded 12-knot averages in 20 knots of wind, and the sheet carries a 9-12 knot cruise under sail or power. No maximum speed is published.

Auxiliary power is twin 270 hp diesels standard, with 380 hp offered — engines sized to move 145,000 lbs with authority when the wind quits.

Interior & Accommodations

Layouts span 4-6 cabins and 7-8 heads plus crew quarters, from an owner's configuration with VIP and guest cabins to a six-cabin arrangement for charter.

The deck plan spreads lounging across the main deck and flybridge in multiple separate seating areas, so a full guest list still finds privacy — the design's stated aim.

Market Position

Eighty-foot sailing catamarans are rare from production yards; most boats this size are custom projects. The FPY80S offers the volume and crew accommodation of that class with series-build consistency behind it.

Within the range it is the sailing counterpart to the FPY80 power cat on the same length, and the step between the FPY70S and the FPY120S.

Who the FPY80S Is For

Buy the FPY80S if your program is crewed, long-range and under sail — an owner crossing oceans in comfort, or a premium charter operation that needs cabin flexibility.

Step down to the FPY70S if the extra volume would sail empty. Choose the FPY80 if the rig is not part of the plan. The FPY120S exists for programs that have outgrown even this.

Frequently Asked Questions

How many cabins does the FPY80S have?

Four to six, with 7-8 heads plus crew quarters — from an owner's configuration with VIP and guest cabins to a six-cabin arrangement for charter. Auxiliary power is twin 270 hp diesels standard with 380 hp offered, sized to keep an 80-foot sailing platform on schedule when the wind quits.

Is the FPY80S the same boat as the Thira 80?

Yes — the FPY80S is the renamed Thira 80, so the platform is proven, including on the yard's own Monaco-to-Saint-Tropez sea trial, which recorded 12-knot averages in 20 knots of wind. The sheet carries a 9-12 knot cruise under sail or power; no maximum speed is published.
