In late 2020, Two Oceans Marine Manufacturing launched the Two Oceans 850 E Power Catamaran.

The Two Oceans 850E Power Catamaran is a completely custom designed and built luxury power catamaran. She is designed by award-winning yacht design firm Du Toit Yacht Design, who has produced more custom catamaran metres and tonnage than any other yacht designer in the southern hemisphere. She is the 13th large custom catamaran that Two Oceans Marine Manufacturing has launched in the last eight years that has been designed by Du Toit Yacht Design.

The Two Oceans 850E Power Catamaran is built in a sandwich construction, using epoxy E-glass with a PVC foam core and carbon fibre for local support and reinforcement structures.

The owner had extremely specific requirements, and this vessel has been custom designed and built to suit their specific needs and application. The Two Oceans 850E Power Catamaran has wider hulls than her slightly smaller predecessors to accommodate transverse berths and larger cabins below deck. The interior layout, furniture design, décor and finishes were done by Du Toit Yacht Design. Her lines are elegant and stylish, and 10 blue LED underwater lights make her a beautiful sight when moored or steaming at night.

She boasts a spacious galley on the main deck, comprising the entire width of the interior. The owners and their guests can relax in the comfortable cockpit or bar area after a day on the water and watch their favourite meal or sundowners being prepared. The galley has plenty of cupboards for long term food and provisions storage as well as large Vitifrigo fridges and freezer space to last several months of exploring. The galley, a marine chef’s dream in terms of space and layout, boats every conceivable modern appliance and endless countertops manufactured from a Shemar, a Corian product.

The interior flooring is teak, and careful attention has been given to the interior finishes, layout, and soft furnishings, giving the Two Oceans 850 a luxurious, yet practical and comfortable feel. This is an elegant and refined vessel: Ralph Lauren fabrics have been used on the day beds and scatter cushions and the wood inserts, television unit, bar and dining table in the aft cockpit are walnut. Careful attention has been paid to stylish LED lights and low-level ambient lighting, all dimmable.

Forward of the galley is a lounge/relax area with a large flat screen TV and state of the art entertainment system. The navigation station and vessel systems console is positioned on the port forward side of the vessel.

The aft cockpit has been designed as the main living and dining area of the vessel and has two large sunbeds and a large walnut dining table able to seat ten people. There is a Vitifrigo double drawer fridge, three 125 l freezers, a prep bowl with a hold and cold mixers, a gas barbeque and plenty of storage space.

The second living area is the very spacious flybridge deck. This provides a comfortable upper lounge area, complete with a dining table, wet bar, ice machine, drinks fridge and sink area. It is the perfect living area to serve canapes and light lunches. A full size jacuzzi and day head complete the flybridge lounge guest area.

The Two Oceans 850E Power Catamaran has two luxurious double, en-suite cabins in both the port and starboard hulls sleeping eight guests in five-star comfort. The wide, spacious hulls have accommodated transverse berths in the owners’ two cabins in the front of the hulls, and the owners’ mattresses are from Hästens. She has two en-suite crew cabins with their own showers in the front of both hulls, accommodating her crew of four comfortably.

The expansive exterior decks are beautifully finished in Burmese teak, and house the main motorised water toys. The Two Oceans 850 has one 5 metre custom RIB with a 70hp outboard engine, one 6.1 metre custom RIB with 2 x 270 hp outboards and two Yamaha Wave runner jetskis on a custom-made aluminium chock above the starboard trampoline. Large Hydraulic cranes facilitate easy launching of the tenders and jetskis.

The Two Oceans 850 has a pair of Cummins 610 hp diesel main engines that provide an economical cruising speed of 10 knots for long distance voyages, giving the vessel a range of over 3500 NM. She has a maximum speed of 22 knots.

Her electrical systems are state-of-the-art, and she has an impressive systems room, accessible via louvre doors in the crew cabins.

The Two Oceans 850 is the epitome of luxury cruising and yet another example of a successful collaboration between owner, boat builder and yacht designer in a complete custom build.
