The market for sailing cats over 24 metres in length is no longer limited to established shipyards such as Sunreef or Fountaine Pajot left. A conspicuous number of large-format one-offs with two hulls are under construction, including at Baltic Yachts or a 110-footer at Black Pepper Yachts (information to follow). And in 2024 "Artexplorer" with 47 metres "Hemisphere" (44 metres) as the largest sailing catamaran in the world.
NB110 is likely to be the first sailing catamaran made of carbon fibre to come from Turkey. U4 Marine has already completed the superstructure and deck for the 32 metre long multihull. The New Zealand design office Greg Young Design has ordered narrow hulls that are set to cut through the sea at over 20 knots from May 2026. U4 Marine primarily acts as a service provider for interior outfitting and is based in Antalya's free trade zone, where over a dozen shipyards build ships for the defence sector and motor yachts for the luxury segment.
Three-stage infusion procedure
U4 entrusted the structural calculations to the French engineers at Rivoyre. A three-stage infusion process is used for the carbon hull, which should result in an optimum ratio of resin to fibres and a displacement of 85 tonnes. Baltic wants to achieve the same value with the 107 Cat. NB110 will be 12.6o metres wide and have a minimum draught of 0.87 metres. Under sail, extended centreboards increase the draught to 4.97 metres.
Rig and sail plan of NB110
The carbon mast, which rises 45 metres into the sky, can be rotated hydraulically. The main and J1 each have 325 square metres in the wind; on rough courses, the 720 square metre gennaker is unfurled. Two 320 hp Yanmar diesel engines power the catamaran. In addition, each hull has a 200-kilowatt electric motor. A battery bank with a capacity of 250 kWh enables fully electric propulsion and can be charged in three ways: the main engines, a 70 square metre solar system with a nominal charging capacity of around 12 kWh and via a hydro generator.
Equipment and comfort
The catamaran offers space for up to eight guests in four cabins. The owner's cabin is located on the main deck and has a private cockpit behind the trampolines. Two VIP cabins and a double cabin are spread over the hulls. The outside areas are modular. Aft, the bulwarks fold down and the bathing platform moves upwards as an extension of the cockpit. The flybridge - where the only outside steering position is located - features a whirlpool, bar and barbecue.
