A Word From The Owners:

"Our 2012 Lagoon 500 named Sea Angel (my girlfriend thinks of dolphins as sea angels) has been a very safe and secure home for us the last 2 years as we have sailed her from the Caribbean island of Grenada (where we bought her September 2021) through the Panama Canal to now Fiji in the South Pacific.

I had always dreamed of sailing the South Pacific since I was a small boy. Now 68 I thought the dream had passed me by, but the onset of Covid changed that for us. I had just retired in 2018 and sold my last sailboat (37’ Irwin) believing my girlfriend and I would travel the world renting houses in different countries, however, Covid dashed those plans and I couldn’t think about sitting at home for years as the pandemic raged. So like a lot of people I started looking to buy a boat that could make the voyage.

We found Sea Angel (then named Nana) belonging to a nice Australian couple in Grenada who had taken very good care of her.

Being new to catamarans I was amazed how strong and solid she was. Coming out of Panama we had 6 days of 25/35 knots right on the nose and I think she handled it better than my girlfriend and I. Once past the Galápagos Islands with the wind turning downwind we just flew. We averaged over 200 knots a day (our record day was 246 knots in 24 hours) and arrived in the Marquess islands only 19 days after we had left. I had never gone so fast in a sailboat before.

There is more than enough room aboard for a family, with 4 queen size staterooms (all have queen mattress over slots that act as a box spring, 2 stern bunks also have memory foam toppers January 2022) each with its own bath (2stern cabins are dry heads with enclosed showers) and the extra comfort of the owners suite which is 2/3 Of the starboard hull, with its own couch for resting or reading and a very large head with large sit down shower) you’ll find your own heaven to rest and relax in.

We love sitting down after dinner and watching a movie on the 32 inch JVC widescreen TV March 2022 which stows in its own cabinet in the salon. With Starlink March 2023 you can stream from any of your favorite channels anywhere you are including on ocean passages

The galley up is open to the rest of the salon so that the cook can socialize with everybody while preparing meals and has all the comforts of home, 4 burner stovetop with oven 2019, two freezers and 2 refrigerators (cockpit Ithotherm March 2022) interior fridge new compressor March 2022) microwave, triple sink basins, utensils, plates, bowls, pots and pans, magnet knive rack with cooks knives, stick blender, electronic food scale, seltzer maker, bread maker, sous vede unit, blender, bamboo stir spoons, many tools and Siemens dishwasher

Having a full size Samsung washing machine with multiple wash programs 2018 aboard really makes it feel like home.

The cooler for the drinking water spout keeps your drinking water at 40 degrees so you don’t need as much ice.

Strong Points: 

Additional stainless grab rails have been installed all over so you never feel unbalanced walking anywhere on the deck.

The visibility from the fly bridge is unbelievable giving clear views to all four corners when docking or maneuvering. Installed iridium go with outside antenna March 2022Installed raymarine i70s multifunction display March 2022Installed raymarine i60 wind instrument March 2022

Raymarine ST70 autopilot with remote in salon.

Installed Raymarine p70 autopilot controller as back up. Independently wired so should work after a lightning strike March 2022

The upgraded Yanmar 4JH4-TE 4 75hp engines New meters were installed by previous owner and told hrs at that time approx 2,900. Meters now read port 976 starboard 968 (full maintenance February 2023 oil change, new fuel filters, all gaskets replaced, pressure test of heat exchanger, 4 new engine mounts installed, new heat sensor ) supply all the thrust you need in close in situations. Yanmar SD 50-4T saildrive gaskets replaced October 2021 supply all the thrust you need in close in situations. Yanmar SD 50-4T saildrive gaskets replaced October 2021

The forward seating area is a great place to hang out on passage and at anchor with its large and easy to install sun shade.

We love that the engine rooms are outside of the living spaces and are large enough that you don’t have to fold like a pretzel to work.

The 5 electric winch’s 3-Harken 60 2 speed 1 Harken 50 2 speed located on the flybridge and the 1-40 2speed located on stern make this boat truly a push button boat. One of the Harken 60’s replaced gearbox July 2022 with a new replacement gearbox in with the many spare parts located on board.

3 of the 4 heads have been upgraded to compositing toilets so you don’t have to spend your time unblocking blocked sanitation lines and also knowing you are not polluting the pristine waters you’ll be sailing in, however, if you prefer to go back to all electric heads, all plumping, holding tanks, pumps and switch’s have been retained for easy conversion.

The new Starlink installed March 2023 is just amazing you can now stay connected to internet wherever you are. We installed the unit in French Polynesia and it has worked wherever we are including offshore, it’s a real game changer."


The Lagoon 500 Sea Angel is a serious  offshore cruising vessel, designed and built for unlimited offshore adventures and independent, luxurious life on board for months at a time. The space is simply huge, as is the storage capacity for a large family, or group of friends who can easily make this boat a veritable home. This Owner's version is also Ideally suited to a skippered charter venture as well, should you wish to tap into the inexhaustible demand for this market anywhere in the world.

The layout is uncommon for a 50' catamaran, and very much based on Superyachts, with its entirely separate owners' stateroom, which mimics what you would expect size-wise on the Lagoon 440 owner's hull, with separate staircase access, giant island berth, lounge area with a big couch, walking wardrobe and extra large ensuite with seperate shower.

Forward to starboard is another dedicated staircase to what can be the crew stateroom, or very private guest stateroom, with a large double cabin and ensuite head / shower area with a screen door to separate it from the main bathroom area.

Port side is another companionway with long hallway, which on Sea Angel ideally house the washing machine, big cupboards, 2 additional stainless steel freezers, and a door at each end for the two guest staterooms, both with abundant storage, queen size bed, large windows and opening portholes / deck hatches, and in the aft cabin a drop-down deck / study area. 

Sea Angel has a completely separate helm station from the aft cockpit, which leaves your family or guests undisturbed when sailing. The large U shape settee can easily sit 10 or 12 people. There is plenty of dedicated storage all around, and a very convenient wet bar with large sink, perfect for preparing drinks, or to clean up the fish you just caught.

On the aft deck, which runs the whole length of the aft cockpit there is a BBQ mounted on the rail, perfectly positioned to keep drips from falling on the gelcoat.

Going up a few easily accessed steps is the very large flybridge / helm station, with good visibility all around and a great view of the sails. The helm seat can sit an entire family. The helm bring every ropes control back to within easy reach of the helmsman, with a foot operated electric winch to handle all your sheets.

Forward is the giant deck and trampoline, with huge deck storage on either side of the anchor well. The windlass was recently replaced with a powerful 2000 watts windlass, which has a new motor and gearbox from 2023 and 100m of brand new chain.

Going inside the large saloon is level with the U shape galley, functional and equipped for commercial catering if desired, with a full size 4 burners stove, oven / broiler, 3 sinks (one for drying), and a fridge / freezer. There is abundant storage all around the salon and galley, with additional under-floor storage as well, perfect for cans or bottles. The salon upholstery has been kept under cover and is in good condition. The table is installed on an adjustable pedestal, so you can use it as a dining table, coffee table, or lower it right down to create a huge lounge or additional bed (please note there is no cushion and you will need to have one made if you desire to use this area as a lounge).

The floor, which is dark timber laminate is in very good condition. The veneer throughout is also in good condition, except for a few areas on the timber fiddles which could be re-varnished.

Going down the port side companionway is a washing machine running off the shore power, or the generator (11Kva Onan), which works perfectly and was just serviced again.

Two large stainless steel freezers are also installed in this hallway, ideally located close to the galley. The freezers can be set to fridge mode if you lower the temperature.

Next to the salon is a large navigation area with swing-out stool, which conveniently disappears when not in use and will preserve the floor (desk chairs are terrible as they scratch the floor).

This Lagoon 500 is equipped with Starlink, which the owner can transfer to a new owner and include in the sale if desired.

  • The sugar scoops (bottom of transom steps) is a little stained and needs an acid wash and polish, but the hull otherwise presents in very good condition with the gel coat undamaged.
  • One small hatch in the port aft cabin has a small leak
  • One of the salon forward hatch has a crack. This was already present when the current owner purchased the boat and has not ben leaking. it is a standard Lewar hatch which is easy to replace, but finding workmen in Fiji to replace the hatch is not easy as the waiting list is very long for repairs.


The Lagoon 500 is a luxurious high-performance boat designed for ocean cruises that includes the innovative features that have made the Lagoon 440 a success.

Three versions of the Lagoon 500 are available: ? An owner?s version with an owner?s hull and two VIP cabins ? An owner?s version with three VIP cabins ? A charter version with five guest cabins Space for the crew can be easily adapted in all three versions. All berths in the two owner?s versions feature lateral access, there are separate shower compartments and bathrooms, and each cabin has a large window along the side of the hull providing natural lighting and an incomparable view of the sea.

The Lagoon 500 was designed by Marc Van Peteghem and Vincent Lauriot Prevost, who have won a record number of awards for multiple-hulled boats (in 2004, boats they designed won the four first places in the famous English Transatlantic race), and benefits from the latest developments in naval architecture.
