GMT Composites has designed and delivered the new custom carbon fibre sea stairs for the latest motor yacht Nordlund 106′. The US shipyard, Nordlund Yachts, reached GMT, when they realized an “off the shelf” boarding solution would not satisfy their client. They wanted a set of SeaStairs that would provide several design specifications not readily available on the market. They needed the stairs offering multiple mounting angles and a landing platform option, as well as being light w/ a maximum storage height of 4.5”.
GMT has delivered a set of carbon fiber sea stairs with eight articulating steps. The lower step has caster wheels to ride on the pier. The stairs were designed for perpendicular mounting on the either side of the Nordlund 106′ superyacht. There is also a trapezoidal platform that mounts to the hull along any of three sides with an extension platform that can mount to the side of this platform to increase platform area. These platforms float. The stair assembly mounts to the platform so that the stairs can be deployed at three defined angles to the hull (15°, 20°, or 55°), depending on the orientation of the platform. When attached directly to the hull, the stairs shall project 90° from the deck edge.
The owner had also requested an innovative low profile hull attachment assembly – something similar to what he had seen used in smaller scale. GMT was able to fabricate a custom stainless steel “V” mounted hardware to the boat that is both low profile and extremely secure.
SeaStairs are a great application of GMT carbon know-how. It keeps the stairs light, stiff, and strong for easy handling and secure boarding. They are finished in AwlGrip to match the vessel and keep them highly corrosion resistant. Treads can be non-skid, or finished in teak.
