Lagoon 42 for Sale, a Broker's Guide to Prices, Specs and Pitfalls

Why there is always a Lagoon 42 for sale

Search any brokerage site for a Lagoon 42 for sale and you will rarely find fewer than a dozen boats in US waters alone. That is not a sign of trouble. The Lagoon 42 has been in production since 2016, Lagoon delivered the 1,000th hull in October 2023, and it has taken over from the Lagoon 380 and the Lagoon 450 as the brand's best-selling boat. A big share of those hulls went into charter fleets, and they flow steadily onto the used market after five or six years of service.

For a buyer, that volume is leverage. You can compare a dozen near-identical boats on price, equipment and history, and you can walk away from a weak survey without losing your only option. The trick is knowing which differences actually matter, because two Lagoon 42s of the same year can be $100,000 apart for good reasons.

What VPLP got right on a 42-foot platform

The Lagoon 42 carries its mast well aft, a layout VPLP also used on the Lagoon 40, 46 and 50 that followed it. With the mast closer to the middle of the boat, pitching drops, the boom shortens and the self-tacking jib sits in a larger foretriangle. Upwind sail area is about 1,119 square feet, with a 743-square-foot mainsail and an optional 732-square-foot Code 0 for light air.

Hull dimensions are 42 feet overall, a 41-foot waterline and 25 feet 3 inches of beam, with a draft of just over 4 feet. Light displacement is about 26,000 pounds, kept in check by infused, balsa-cored construction. Patrick le Quément gave it the squared transoms and vertical-window coachroof that defined Lagoon styling for the next decade, and Nauta Design handled the interior.

Sea trial numbers, under sail and power

In a test on Biscayne Bay in light air, a Lagoon 42 made 6.1 knots at 50 degrees apparent in 11.6 knots of breeze, and 7 knots with the Code 0 in about 10 knots of wind at 75 degrees apparent. The same reviewer later reported 15 knots of boat speed with a spinnaker in 22 knots of true wind on flat water off Bimini. That spread tells you a lot: the 42 is ordinary in very light air without a Code 0, and genuinely quick once the breeze fills in.

Under power, the optional twin 57 hp Yanmars delivered 7.8 knots at 2,000 rpm, about 8.1 knots at 2,400 rpm, and 8.7 knots at 3,200 rpm, which was wide open throttle. The standard engines are 45 hp Yanmar 4JH45s, and they are fine for most coastal use. The 57s are worth a premium if you plan long motoring legs into a headwind or regular passages in open water.

Owner's version or four cabin charter boat

The three cabin owner's layout gives one hull to a master suite with an island berth aft, a desk or sofa amidships and a large head forward, and puts two guest cabins with their own heads in the other hull. It is the layout most private buyers want, and it holds a premium of several tens of thousands of dollars on the used market.

The four cabin version, with either two or four heads, dominates charter fleets. It is the easiest boat to resell into another charter program, but for a couple living aboard it wastes space that could have been storage. If you need four cabins for a family, look for a privately ordered four cabin boat rather than an ex-charter one, since it will typically have better equipment and lighter wear.

Reviewers flagged a few small design flaws that remain true of most used boats: a top-loading fridge awkwardly close to the companionway steps, limited ventilation in the saloon with no overhead hatch, and a coachroof edge without proper handholds or nonskid. All are fixable with small upgrades, but they are worth seeing for yourself on a viewing.

• 3 cabins, 3 heads: owner's version for couples and liveaboards
• 4 cabins, 2 heads: classic charter compromise, most common used
• 4 cabins, 4 heads: maximum privacy, least storage

Two numbers that catch out US buyers, tankage and air draft

Standard tankage is light for a 42-foot cruiser: about 79 gallons of diesel and 79 gallons of water. SAIL magazine's test called the tankage light and noted that owners who want to venture farther will need to increase both. For extended cruising, check whether the boat has had extra fuel capacity added and a watermaker fitted, because without them the boat is effectively a coastal cruiser that needs regular dock stops.

The other number is air draft. The Lagoon 42 stands nearly 68 feet above the waterline, which is too tall for the 65-foot fixed bridges on the Atlantic Intracoastal Waterway. East Coast owners have to make outside passages between inlets rather than motoring the ditch, which is a real consideration if you plan to migrate seasonally between New England, the Chesapeake and Florida. If ICW access matters, look at the shorter-masted Lagoon 40 instead.

How to read a Lagoon 42 listing like a broker

Start with history. A boat that spent five years in a charter base will have high engine hours, worn interior joinery and tired upholstery, but it will also have a documented maintenance trail from a professional fleet. A privately owned boat with low hours can be a better buy, or a worse one if it sat unused in the tropics with systems that were never exercised.

Next look at equipment. Generator, air conditioning, lithium batteries, solar, a watermaker, an electric winch at the helm and upgraded electronics can easily add up to $80,000 to $120,000 of value. A cheaper boat without them is not a bargain unless you were planning to choose those systems yourself.

Finally look at location and tax status. Many Lagoon 42s are listed in the BVI, Martinique or the Mediterranean. Factor in US import duty, a delivery or shipping cost and the time to bring the boat home before comparing it with a duty-paid boat already in Florida or the Chesapeake.

What a Lagoon 42 costs each year

Plan on about $30,000 to $60,000 per year in the US, excluding depreciation, for insurance, a slip, a haul-out, engine and saildrive service, canvas, and steady upgrades. At over 25 feet wide, the Lagoon 42 almost always needs a double slip or an end tie, and in busy markets like South Florida that alone can exceed the rest of the maintenance budget.

The mechanical side is straightforward: two four-cylinder Yanmars, saildrives, a generator on most boats and a simple fixed-keel hull. Saildrive diaphragms have a fixed replacement interval regardless of hours, so verify when they were last done.

Values, the current Millennium boat and long-term resale

The Lagoon 42 has held its value well. Early boats from 2016 and 2017 often ask $340,000 to $440,000, close to what their first owners paid with options, while 2021 to 2024 boats ask roughly $450,000 to $650,000. Recorded sales cluster around a median of about $499,000.

Lagoon still builds the boat, now marketed as the Lagoon 42 Millennium, and new sail-away prices with a realistic option list run roughly $650,000 to $850,000. Continued production and a huge owner base protect resale, because buyers know parts, service and know-how will stay available for decades.
