Originally built and delivered in 2001 as "Double Trouble”, MerSea has crossed the Atlantic with the ARC Rally, cruised the Caribbean, and spent years based in Florida. She was acquired by her current owners in 2021, returned to Canet-en-Roussillon, and underwent an extensive refit over the course of three years. After sailing in the Mediterranean and crossing the Atlantic early 2025, the current owners intended on spending at least another year sailing the Caribbean. However, for personal reasons, they recently made the difficult decision to sell what they consider their “perfect boat.” This is a rare, highly capable performance cruising catamaran, refitted to an exceptional standard with a focus on quality and reliability. MerSea is fully equipped and ready for extended bluewater cruising. MerSea is currently available for viewing in St. Vincent and the Grenadines or Martinique.

- 1 x GLOMEX RA304 Glomeasy antenna
HOUSE ELECTRICITY (SERVICE)
24 volts and 220 volts 50Hz
• Electric system
Numerous defaults to original electric remote relay system (initial signs of combustion) so it was entirely stripped out and replaced with resettable fuse boxes for house lighting and circuit breakers (at switchboard in saloon) for nav equipment, nav lights, pumps, fridges etc.
Absolutely all cabling onboard was reviewed and either reconnected with new connectors (heat shrink+glue tubing), outlets, lighting etc and/or replaced.
Large amounts of old unused cabling and equipment was removed from the boat including: HDMI cabling throughout the saloon and cabins; old TVs, VHS/DVD players; several 24/12v converters installed in the bilges;
6 x halogen lamps that supplied the fibre optic courtesy lighting in the saloon and cabins that was faulty, inefficient in terms of energy and space. Could be replaced by LED strips if future owners wished.
• 6 x 300Ah 12v ULTIMATRON pro lithium batteries (3 pairs = 900Ah 24v) with internal BMS monitored via smartphone. Batteries, cabling, switches, busbars etc… new 2024. Installed in large ventilated, easy access area under saloon seats.

• 1 x 12.5Kw Phasor Marine generator 220v 60Hz. Dates from approx. 2011 (5 600 hours)
Full overhaul of Kubota engine in 2023. Works well!
As the generator is 60Hz and the appliances currently on the boat are 50Hz (kitchen, washing machine….), it runs the water maker, heats water and charges the house batteries though, as charging is through the VICTRON Multiplus, it is necessary to “downgrade the input current” so charging is not full power.

New 2023. Prevents electrolytic corrosion and guarantees a safe electric system. Eliminates electrical continuity between AC shore power and the boat. Eliminates the need for galvanic isolators and polarity alarms. Shore power is fed to the primary side of the transformer and the ship is connected to the secondary. Input: 115 or 230 V. Rating: 32 / 16 A.
• Water, fuel gauges and voltmeters at switchboard
• Remote control panel for the generator
• Waterproof shore 220 V (AC) inlet, with extension cord Both new in 2024

The old freshwater tanks were integrated amidships in the bilges of each hull.

New owners decided to remove entirely and replace in 2022 with polypropylene tanks. Without altering the cabin soles, the only access is through the lifting floorboards. It was necessary to link 3 tanks together, each side, to approach the original holding capacity.
• 1 x watermaker SEA RECOVERY Aqua Whisper Compact SRC AWC 1500-2 230 V (60Hz so runs off generator). 200-250 Litres/hour.
Full overhaul in 2024 with various parts replaced, inc new booster pump and both membranes.

New 60L gravity tanks fitted in 2023 in port and starboard heads
• 3 x fuel tanks: total 1400 litres

All new fittings and seacocks in 2023-2024. TRUDESIGN for all the fittings and seacocks below the waterline except for engine room where bronze has been used and some higher fittings where TRUDESIGN wasn’t available in the necessary lengths for hull thickness.
• 2 x YANMAR 4JH3-DTE In-Board 125 HP turbo diesel engines
Integrally dismounted, stripped, rebuilt, exchangers changed, hoses, seals, silent blocks, rust primer, repainted etc. etc. by Chrisian ROL, in Canet-en-Roussillon in 2023-2024.
Both run perfectly and total absence of electronics!
Hours Port: 5 000
Hours Starboard: 5 200
115 m² Full Batten Mainsail, 3 reefs
110 m² Gennaker
41 m² self-tacking Solent-jib

FEW WORDS FROM CATANA
Design
A boat that is easy to sail with a family crew or short-handed, balanced so that it can hold its course well and offers a smooth and precise helm in any weather. Tacking and reefing is easy and done from the cockpit. An extremely solid boat, reassuring and efficient in all conditions.
Stability
An excellent beam/length ratio and hull inclination give a CATANA outstanding static and dynamic stability. A cruising catamaran offers you an important stability (righting moment several times greater than that of a monohull of comparative length. Thus, no more heeling. This feature is even enhanced on a CATANA. To increase the overall stability of the boat without overly increasing its total width (meaning added weight and efforts on the structure), the hulls are tilted outwards.
Hulls
The elongated, torpedo-shaped hulls lessen the "rocking chair" effect in heavy seas and create less drag than a normal wide-hulled catamaran. Boat speed is therefore higher for the same sail area or equivalent engine power. The aerodynamic shape of the coach-roof windows reduces windage, as well as being more aesthetically pleasing. When lifting the daggerboards, there is no drag when reaching or running, the boat cuts effortlessly through the water and cruising speed is much higher during long passages downwind. The volumes at both ends of a CATANA floater are important, thus more resistant to pitching in swell.
Centering the weights
The elongated waterline, as the centering of the weights, stabilise the boat and reduce pitching.
Bulbed and tulip-shaped bows to prevent pitching
The bulb section under the waterline is tuliped towards the deck, which greatly improves performance in heavy weather. The bulb increases the volume of the hull submerged at the bows, reducing pitching and submersion of the hulls. The tulip shape produces a resistance to pitching directly linked to the rapid increase in volume on top of the hull. The very narrow section at the waterline means excellent performance in calm seas.
Unsinkability
Even when totally filled with water, the boat will not sink. The density of products used, the volume of foam in its sandwich construction and the absence of ballast provide buoyancy. The totally waterproof bulkheads add to the insubmersibility of the boat. In the case of a collision strong enough to crack the hulls, no water can enter the living quarters. The "crash boxes", with waterproof casing forward and aft, will keep any holes or leaks away from the living quarters in the event of a collision.
Sandwich construction
CATANA boats are built entirely of sandwich construction under vacuum. For a catamaran where each hull sails over different waves, its strength and long life depend on the rigidity and consistency of the boat's structure. The core of the hulls and bulkheads is made from PVC foam, with a density of 75 kg/m' and a minimum thickness of 20 mm. The core of the decks, platform and coach-roof is made with foam up to 40 mm thick. Thick gelcoat (8/10 th) + Uni-directional, high-resistant + tri-axial glass fiber + core of PVC foam + uni-directional, tri-axial Twaron® materials.
