S/V Dorothy Rose is a 2010 Lagoon 400 Catamaran (Hull 16) For Sale By Owner located at the Florida / Georgia border.  This is the very desirable and highly sought-after Owner’s Version with 3 cabins and 3 heads.  She has had many updates recently including fresh bottom paint in 2022, engines / saildrives / genset fully serviced 2022, new refrigeration 2021, new air conditioning in 2020, new sails in 2019, and watermaker new in 2019.  She is fully loaded and turn key.

The 400 is a remarkably designed, “galley up” catamaran, the most popular of its category with more than 600 hulls built. There is sliding window connecting the galley to the cockpit keeping everyone in the conversation, creating a large open space. There are 3 cabins and 3 heads with their own private bath and showers. There are “V” berths at the fore of each hull that can be used for extra storage or sleeping. Cabins are light, bright and well ventilated along with new Cafrano fans in all.

The Lagoon 400 is one of Lagoon’s most successful models to date. Lagoon began building this model in 2009, production finished in 2017, so a lengthy run of 8 years. The innovation in the Lagoon 400 is the amount of living space that has been packed into this boat. Also, due to the long production run, parts are available.


The 400 is built using Lagoon’s tried and trusted method: solid laminate below the waterline and balsa core above, including the decks. The hulls and decks are infused with polyester, and Lagoon adds vinylester resin to the hulls as an osmotic barrier.


Sailors won’t be disappointed with the Lagoon 400, especially off the wind. The main goes up easily with the electric wench. The genoa is on roller furling and it is easy to handle. All lines are run back to the helm station. She loves a good beam reach. Downwind sailing with the parasailor is a dream come true in comfort, even in very light wind conditions for the Parasail and it is beautiful.

In moderate winds (10-20 kts), the Lagoon 400 sails well from 50° to 140° TWA. Running downwind, the parasailor is very versatile and can be use not only dead down wind but you can use it any time the wind is from 90 degrees to 90 degrees.

You can expect a SOG of around half of the apparent wind, up to 10 kts of boat speed. All the sail handling is done from the elevated helm station at the port main bulkhead which has become a Lagoon trademark for this sized boat.

Easy to Handle

The running rigging is simple, all lines, sheets and halyards come back to the helm and all the work can be done on the winches, including one electric. Raising and lowering the main and reefing works well from the helm.

Getting about the boat feels safe, as the layout has been kept clean with wide flush decks with recessed hatches. The bow lockers will comfortably store all your lines, fenders, and sails, and they have a false floor giving you an additional lower section to store stuff.

Living Space

This is where Lagoon has excelled on the 400 and the design has stood the test of time. This is the 3-cabin configuration with the owners suite having more closet space and a nice large bathroom and separate shower.

The salon and galley are very roomy for a boat this size, with plenty of storage under the saloon sofa. The Galley has a new refrigerator and a freezer, oven, toaster oven and stove and LG 24” SmartTV monitor.

The salon also includes a handy nav station with a remote control for the autopilot, a saving grace in wet weather. Head down below, and you will also note the living space that you get on these boats versus some of the competition. There is also plenty of stowage space.
