Lagoon 420

Introduced as a hybrid-powered cat, the newest version can growl with the motorsailers. A boat review from our July 2008 Issue

By Mark Pillsbury August 15, 2008

Given the disdain of the French for fast food, I hope Lagoon will forgive my suggesting that for its 420 catamaran, it borrowed Burger King’s “Have it your way” approach to pleasing customers.

The stylish 420 made its debut at the U.S. Sailboat Show in Annapolis in 2006 as the first hybrid-powered production sailboat and immediately caught the attention of buyers intent on going green. Rather than traditional diesels, the 420 Hybrid is powered by a pair of electric motors and a battery bank that can be recharged either by shore power, an onboard diesel generator, or by the boat’s propellers when sailing faster than 7 knots. For those not convinced that the time for hybrid power has arrived, the 420 is also available with 40-horsepower Yanmar diesels and saildrives.

But Lagoon hasn’t stopped there with its versatile and popular 420. At Strictly Sail Miami last winter, it introduced a third version, with a beefed-up power plant, for owners who might have considered a power cat. This latest iteration of the 420 sports twin 75-horsepower turbocharged Yanmars and saildrives. At a cruising speed of 2,200 rpm, we averaged 7.7 knots; wide open in shallow Biscayne Bay, we topped out at just under 9, though Lagoon America’s Nick Harvey said the boat should do at least a knot better in deeper water.

Lagoon 420 Review – The Taste of Sailing!

By Daniella Wender – May 12, 20152

A catamaran for the experienced and new sailor alike is the Lagoon 420. This two hulled, approximately 42 foot, sailboat propelled, the charter yacht is perfect for a small family sailing vacation or if you want to take off sailing all alone. With its ease of maneuvering across the water, you will find true enjoyment chartering on a Lagoon 420.

Build your Sailing Confidence!
As your first charter yacht, the Lagoon 420 is a good choice to build up your sailing confidence. When traveling by sails, the two hull design resists heeling.

If you choose to use the twin engines, this will allow the vessel to make tighter turns. With the sail and stout beam layout, you will have the ability to pick up and begin your voyage without fuss.

The Lagoon 420 handles easily with 1 person controlling the lines at the helm so there is no need for a crew.

Lagoon 420 • Combines great liveaboard with modern sailing and powering systems

This innovative cruising cat combines great liveaboard accommodations with thoroughly modern sailing and powering systems.

We set off from Miami’s Bayside Marina in the midst of the Strictly Sail Miami boat show and motored south to the broad shallow expanses of Biscayne Bay. The new Lagoon 420, which was fitted out with twin 75-horsepower diesel engines instead of the standard 40-horsepower engines, motored with real authority. At cruising revs we had it up to 8 knots without any trouble and when we pushed the throttle all the way forward we got the 420 over 10 knots…that’s fast for a 42 footer.

South of the Biscayne Boulevard bridge, we hoisted the big, high roach mainsail and rolled out the genoa. With the engines off, we trimmed to a broad reach and set off down the bay in the steady 10 to 12 knots of easterly breeze.

Multi-Hulls’ Review

Lagoon 420/421- Priority: comfort…and volume!

Here is a model which without a doubt represents Lagoon’s most comfortable offering in this size – perhaps even too comfortable, certain people would object. But with its load-carrying capacity and the pleasure of life aboard, the 420, later offered as the 421, is quite a ‘best of’!

Do you remember the Lagoon 420? Launched in September 2006, this cat had no hang-ups about displaying a bulky coachroof and a very high freeboard. With this model, the company certainly designed its most comfort-oriented boat. A bold gamble, but one which finally paid off, as 179 Lagoon 420s were built in three years. But the real challenge was to develop hybrid propulsion, then a 100% motor version with the same platform. After an intense test campaign – transatlantic, West Indies – Lagoon thus presented a catamaran propelled exclusively by a Leroy Somer hybrid system. The first 70 models, a year’s production, were delivered with this set-up. The system was a little disappointing from a performance point of view, and had reliability problems. Lagoon decided to give a lifetime guarantee, and more rationally, offered traditional diesel replacement engines to all the owners. All accepted…except two!
