Lagoon 42 check-in checklist

Updated 2026-09-28

The Lagoon 42 is a four-cabin cruising catamaran, and its check-in is a catamaran check-in first: two hulls, two engines, a trampoline and davits. On top of that, the boat puts its rig and its controls in places a generic list does not expect. Here is what to look for at the helm, in the rig and on the centre beam, with the reviews each point comes from.

What is different about the Lagoon 42 at check-in

Three things set this boat apart at the check-in. The mast stands well aft, about halfway along the boat, with a tall rig and a short boom. The headsail is a self-tacking jib on a track ahead of the mast, and the track has adjustable stop pins that are easy to overlook. And there is no flybridge: the helm is a raised station to port on the main bulkhead, where the wheel, the engine controls, the instruments and almost every line come together at two winches.

That last point concentrates the check-in. Most of what you would inspect across a monohull cockpit is in one place on this boat: the helm console, its cover, its seat, and the winches beside it. Give that station its own few minutes.

The 8 items where the Lagoon 42 differs

Each hint below is the one the Dockproof app shows for this boat.

Mast and boom Rig and sails

On this model the mast stands well aft, about halfway along the boat, with a tall rig and a short boom. Photograph the mast foot and one looking up the mast. On the boom, check the mainsheet fitting and the gooseneck; an accidental gybe leaves its mark there.

Mainsail Rig and sails

This model can carry the optional square-top mainsail, which has extra area at the head. Open the cover and photograph the head of the sail and the upper battens as far as you can see them, then the battens and cars lower down.

Headsail and furler Rig and sails

On this model the headsail is a self-tacking jib on a track ahead of the mast, and the track has adjustable stop pins. Slide the car from side to side and photograph the track, the car, and the pins. Unfurl the jib at the berth if the wind allows and photograph the sacrificial strip on the leech.

Gennaker and bowsprit Rig and sails

On this model the Code 0 or gennaker sets on a sprit fixed to the centre beam between the bows, the same beam that carries the forestay and the anchor roller. Photograph the sprit, its fitting on the beam, and the sail bag with its label.

Winches Rig and sails

On this model almost every line ends at the two winches beside the raised helm, and one of them may be electric. The Code 0 sheets go to separate winches on the aft quarters of the cockpit. Turn each winch by hand in both gears, run the electric one briefly, and photograph each position. Count the handles and photograph them together.

Helm station console Flybridge

This model has no flybridge. The helm is a raised station to port, on the main bulkhead, with the wheel, the engine controls, and the instruments. Photograph the console with the screens on, and check whether the instrument plastics are crazed by the sun.

Helm bimini Flybridge

The helm station has its own cover over the seat, a rigid top or canvas depending on the boat, with a window above the wheel to watch the mainsail. Photograph the cover from below and from the coachroof, the window, and the frame mountings.

Helm seat Flybridge

The helm has a bench seat wide enough for two. Count its cushions and lift them. It is open to port and gets the sun, so the upholstery fades there first.

Where these items fall in the walk

The Lagoon 42 check-in in the app has 68 items. The model-specific ones are in rig and sails (5), flybridge (3). Everything else follows the generic catamaran walk, which the catamaran check-in guide covers item by item.

Before you go

• Ask whether your boat has the optional square-top mainsail. If it does, the head of the sail carries extra area; photograph it as far up as you can see before you leave.
• If one of the helm winches is electric, run it briefly at the berth, with the base manager present if you can.
• The Code 0 sheets run to separate winches on the aft quarters of the cockpit. Include them when you count and photograph the winches.
• Everything in the catamaran check-in guide applies here: the trampoline, both bows, the bridgedeck underside, both ladders, both engines, and the davits.

The deposit on a boat this size

At about 42 ft, the Lagoon 42 falls in Sunsail's 42 to 44 ft catamaran band: a published deposit of $8,005 without the damage waiver, or $1,091 plus $140 a day with it (Sunsail, Yacht Damage Waiver). Your own contract sets your deposit. What the waiver and deposit insurance leave to you is in the deposit insurance guide.
