Marsaudon Composites TS5


The Marsaudon Composites TS5 sits at the very head of the performance cruising catamaran category, well proven as a racing machine at St Barths and appreciated as a world cruiser. Designed by fast cats supremo Christophe Barreau (who has a whole range of fast Catana Catamarans in his design archive), they are among the fastest livable multihulls in the world (capable of 350+ miles a day). If you want to make that step up on performance, this cat should be on your shopping list.

The profile is muscular and sporty, with long, mean straight bows that instantly say “racing catamaran”. The angular coachroof gives owners plenty of space and panoramic allround views. With the coachroof set back, a high freeboard, and big inverted bows, she cuts through the sea quickly. Add a powerful 20m Lorima rotating carbon mast and sail plan and you begin to understand how she achieves such high speeds. I can only think of one other boat to take her on in an offshore race.

  • These boats are fast! They are among the fastest liveable multihulls in the world right now.
  • The TS5 has more living space than the TS42. It´s the bigger sister.
  • She is a very striking looking catamaran – she looks mean and a real speed machine even at anchor.
  • The views in the salon are panoramic.
  • There has been an almost maniacal attention to weight saving on this boat. She is light and accelerates quickly.
  • There are many custom options available – use of carbon in the bulkheads, forward beam, compression beam and mast for example, the rotating mast.
  • Those overhang seats and tillers aft give you the full sailing adrenaline rush. And you thought you were letting it all hang out o an Outremer bucket seat?!


  • These are technical boats to sail and will only suit experienced sailors.
  • Even the non sailors onboard are likely to feel intimidated by the power and speed of this yacht.
  • The interiors of these boats are pretty spartan – it´s all about weight saving inside. She has her charm, but don´t expect to feel cosy.
  • The underwater hull of the TS5 is shaped for speed with slim, taut lines designed to reduce the wetted surface- so that means less living space, particularly down below in the hulls.
  • There´s no table in the aft cockpit- there´s nowhere to really hang out in the sun.

Strong and Light

These boats are stiff, light machines that have been designed to get you places fast. They are pretty minimalist inside, but if you want a fast cruising cat which you can win the occasional race on, this boat is hard to catch on most points of sail if she is handled well. The weight clocks in at around 8 and a half tonnes – pretty impressive for a boat this size with such a powerful sail plan. If you add all the carbon options on you´ll be able to reduce that by another tonne, but that requires deeper pockets.

Marsaudon Composites, from Lorient in Brittany, have quite a reputation in the offshore cruising and racing world. The TS5 is built using an infusion process in a female foam-glass-poly/vinylester sandwich mold, and carbon structural elements can be added to suit the owner´s requirments. So the aft beam and main bulkhead can be made in carbon as can the forward beam and the compression beam, for example.

Simplicity Rules

Inside, this boat is all about simplicity. The finish doesn´t hit the heights of something like the Ocean Explorer OC60, but then to be fair we are not in the same price bracket here.

The galley is L-shaped, with plenty of storage space. There´s a large L-shaped dining area that sits 6-8 people and a decent nav station. The general feeling is of a light, functional space that gives you the comfort you need without the weight. We love the skylight and down below you can choose between the 3 cabin owner´s version or the 4-cabin version which are home to pleasant, bright and wide spaces in the sleek hulls. The bunks measure 200 x 160 and the decor is warmer down here with wood-effect headlining panels. The big aft facing windows in the back cabins will grab your attention.

The heads and shower area is pretty cosy though!

The furniture is all foam cored to save weight.

On the Water

If you have chosen some of the sportier options, this boat will fly. Well, it´ll fly without some of the sportier options, it´s just a case of the level of speed that you require. 25 knots in 28 knots of wind? It´s been done. 30 knots? In the right conditions, yes. The bottom line is that she´ll comfortably sit in the high teens and low 20s in the right conditions.

With the Lorima rotating carbon mast, carbon crossbeam and the rest you can pull together a seriously powerful and light package from this manufacturer. The rig is set aft, Gunboat 68 style,  and 40hp engines with three-bladed, folding propellers will push you through the chop efficiently if the wind dies. The TS5 comes loaded with daggerboards, so you´ll be beating into the wind at speed while minimising your leeway. The bucket seats, tiller steering option and big daggerboards are all geared up for people who love the thrill of sailing at speed. This boat is all about fun on the water: sitting in those bucket seats on the windward side, over the side of the hull with the carbon tiller in hand flying along will give you a real buzz.

The speed log should frequently hit numbers very close to true wind speed and you´ll be sailing between 40 and 60° to the apparent, although she can go to less than 30°.


This speed machine won´t suit everyone of course- it´s designed for experienced sailors who want maximum fun out on the water and who want to reach their destination fast. She´s pretty minimalist (there is no table in the cockpit for example), but if it´s a super-charged, finely balanced, seaworthy catamaran you´re after,  this could be it.
