catamaran MUMBY 48 (vente suspendue)

On the multihull market, there are few units built in aluminum! Excessive manufacturing costs, replicability using impossible molds, image of aluminum as being an unsuitable material for the construction of multihulls (totally false of course!!), yet this fantastic construction material has proven itself! This MUMBY 48 is an all-terrain boat equipped with lifting appendages (the key to any successful multihull). The construction is superb, the equipment and preparation carried out by a very competent and qualified skipper owner. Lots of new equipment (plumbing, electricity, electronics, watermaker, heating, annex…..). A good-running multihull, perfectly suited to long-distance off-piste cruising
Description
NAUTILUS is a Tim Mumby designed 48 foot Aluminium Performance Sailing Catamaran.
The Mumby 48 is well renowned worldwide for strength, speed and safety. Many examples have circumnavigated (see YouTube: Sailing Jupiter).
NAUTILUS is fully off grid and fitted out for extended passage making. With three double cabins and one single berth.
Recently equipped for world cruising NAUTILUS was Initially built and launched in 2015 with hulls, insulation, engines, rigging, spars and sails completed.

Internals were completed in 2022/23 with all new equipment from hull up: wiring, plumbing, electronics, head linings, galley, toilets, showers, deck upgrades, heating, rudder upgrades, water maker, painted, antifouled.
NAUTILUS is a pedigree aluminium performance cruising catamaran. She is ready to cruise the world, but could benefit from some completion internally such as shelves and some internal linings. Pipework and wiring have deliberately been left exposed for easy maintenance. She has been fitted out with the lightest materials. And where lining materials were not needed, the hull/insulation was left bare, which saves weight. A critical component of fast cruising Cats is to keep them light and not to overload them.
The interior is spray insulated with 1 – 2″ closed cell foam and lined with Garnica ultralight ply strips on the ceilings and hull sides. There are some head linings and hull lining needing completed.
She is not perfect in terms of finish. And has a few minor dents and scratches. If you do dent or damage the hulls you can simply cut out the offending piece and weld in a new plate. That is the beauty of aluminium. Plus, being non corrosive, the hulls are very low maintenance.
NAUTILUS is not a harbour gin palace. She has bumps and scratches from adventure sailing. If you want a glossy, white, polished Yacht please look elsewhere.
The current owner is a highly experienced professional Yacht/Tall ship skipper with 40 years sailing experience. Recent passages include North of Scotland to Spain and Spain to Amsterdam.
Please note; NAUTILUS still requires dagger boards to be installed. We have a quote £5,000 each for new boards to be made by a professional marine aluminium fabricator. She can sail well, even reasonably upwind, without the boards. And, of course, downwind dagger boards are not needed at all.
Currently berthed in Amsterdam.
