The Boat

Ondine is a 1991 Lagoon 55 designed Marc Van Peteghem and Vincent Lauriot Prévost. I feel I have to point that out as I’m really *not* a fan of the modern Lagoons – which are really designed to cruise around the BVI’s with a martini in hand.  Not that there’s anything wrong with that – unless you want to cross an ocean.  The Peteghem/Prévost team are famed for their racing designs, and they took a high performance cat and converted it into a fast, strong, luxury cruising machine. Most people credit the Lagoon 55 as being the boat that opened peoples eyes to what a catamaran can be. When the Lagoon 55 was launched in the 1980s, catamarans were scoffed at by most sailors as unsafe esoteric boats. But today, if you go to almost any popular cruising destination you will see huge numbers of catamarans. The Lagoon 55 is characterized by low windage, high bridge deck clearance and less weight than her more modern (Lagoon) contemporaries. In other words she is a sailors boat. Here are the details.


Overall description

Ondine sleeps 8 in three double cabins (two on the starboard side, and one on the port) and one set of bunk beds in the port side.  Each of them have private heads.  We’ve designated the port aft cabin  “Master Cabin”.

Master Cabin

The stoarboard aft cabin is the “guest cabin” (please come and visit).

Tthe starboard forward cabin – which I think is the nicest on the boat is Paloma’s room.

And Ronan has the bunk beds on the port side (he calls it the Blue Vert cabin – SIC).

We converted the heads from manual to electronic this year (2010) as that’s just one of those little things that can make life so much more pleasant.  Ondine was originally designed to have a crew quarters as well all the way forward on the port side with a private access through a deck hatch.  But we’ve taken that out and converted it into a storage facility for linens, clothes, laundry, and everything else that just won’t fit.

We’ve put a washing machine in there because I *hate* doing laundry by hand.  The crew had their own private head right next to Ronan’s but frankly 4 heads is already too many so we’ve taken that out, opened it up to Ronan’s and converted it to a dedicated shower.  Which also means that you can walk all the way through to the “laundry” room from Ronan’s whereas before you had to enter through the deck hatch (which you still can if you are so inclined).

We have a “galley down” on the starboard side – I have to say I prefer “galley up” so that you can socialize when you cook.  But the Galley is big and spacious – plenty of head room for a 6ft 3 in (1.9 meter) person.  And is easier to cook in when under sail. Paloma’s room is forward of this and the guest room is behind it.

In the same location in the port hull is the navigation center.

Nav Station

Again, I’d prefer it to be up.  But it’s great to have a desk to work at and given that we have laptops, iPads and a Garmin system at the steering position, we don’t have to do actual navigation down there.  It’s a great work/writing desk and is the the electronic command center.

Forward of Paloma’s room on the starboard side – accessible only from the deck was a work room.  When we bought the boat it had a drill press, grinders, a work bench with a vice on it.  And I know that I should probably have been excited about that, but I find that the work I do on the boat is done wherever the item to be fixed is.  Or in our spacious cockpit.  So that’s gone and it’s now our sail locker.
