Designers Van Peteghem and Lauriot-Prévost shaped a cruising catamaran measuring 40 feet 7 inches long with a 23-foot 4-inch beam. The design deliberately traded some of its predecessor’s sportier edge for more living space and easier handling. Around 280 boats were built through 2006, and the type has since become a classic reference among ocean-cruising catamarans.
Design and Construction
VPLP drew the 410 as a roomier boat than the Lagoon 42. Its wider hulls increased lateral stability, safety, and volume. The keels were made fuller, with more volume at the hull ends, to reduce pitching. The slim hulls slip smoothly through chop, while the high bridgedeck does not slam in seas.
Below the waterline, the 410 is solid fiberglass; above it, the structure has a balsa core. That construction is fine as long as the core stays dry, but it can be expensive to repair if moisture gets in. Early boats had punchy sail-area-to-displacement ratios and were sturdily built. The model has plainly stood the test of time.
The very short fin keels keep draft to 3 feet 11 inches. That shallow draft is useful, but the keels also limit the boat’s ability to point.
Rig, Performance, and Handling
The rig was rebalanced with a smaller mainsail and larger jib while retaining the same overall sail area. The fractional sloop carries 603 square feet in the mainsail and 409 square feet in the genoa.
The Lagoon 410 is no performance cat, but when kept light, it performs very well for a cruising catamaran. It is pleasant to sail, handles well in a seaway, and pitches only moderately. On a reach, it will make 50 to 60 percent of wind speed. Writing in Multihulls World, testers recorded more than 8 knots off the wind in a force 4. Close-hauled in 16 knots of true wind, it makes about 7 knots, building to just over 10 knots as you bear away and the wind freshens.
The short keels hinder pointing. The boat can lie at 45 degrees but does better when dropped off to 10 degrees, and 100-degree tacks are achievable in decent conditions. Owners tend to settle around 50 degrees close-hauled. Despite lacking a self-tacking jib, the 410 is easy to sail short-handed.
Folding propellers and a gennaker can further improve performance for an owner inclined to refine the package.
Cockpit and Accommodation
The saloon is set level with the cockpit, an innovative arrangement at the time that improved movement between the two social areas. The boat is easy to move around, with decent headroom and wide passageways. Compared with the Lagoon 380, it offers more living space, more storage, a more comfortable galley, and spacious heads for its size.
The raised helm, offset to port, was an undoubted success. It provides good visibility, and the arrangement has since been widely copied.
Charter layouts can accommodate as many as four double staterooms, each with its own head. In the owner’s layout, the forward starboard space instead becomes a roomy shower room and study.
The S2 upgrade introduced larger cabin windows, a rearranged galley, halyards led to the cockpit, an electric winch for the mainsail halyard and mainsheet, and bow anchor placement.
Machinery, Access, and Maintenance
The engines sit beneath the bunks. This location centers their weight, but reaching them through the aft cabins routinely disrupts those spaces. Otherwise, the boat is very easy to access and work on, and the S2 is particularly well organized.
The interior furnishings don’t wear especially well, and delaminating wood interiors do appear, though this is an easy fix. Because the balsa core above the waterline is vulnerable to moisture, all deck gear should be checked to ensure it remains firmly attached and properly sealed.
Owners have also reported slapping against the flat surface beneath the aft berths, which can become noisy in big waves.
The Verdict
The Lagoon 410 marks the point when Lagoon turned firmly toward comfortable cruising without abandoning a sail plan lively enough for real passages. It rewards a buyer who keeps it light and accepts its limitations close-hauled. Its layout DNA still echoes through newer catamarans.
Pros
- Wider, more stable hulls
- Level saloon-to-cockpit living space
- Easy short-handed sailing
- Good visibility from a successful helm design
- Sturdy early construction, with solid fiberglass below the waterline
Cons
- Balsa core above the waterline requires well-sealed deck gear to avoid costly moisture damage
- Short fin keels restrict pointing and close-hauled performance
- Interior woodwork is prone to delamination
- Slapping beneath the aft berths can be noisy in heavy seas
