The Nautilus-2200 is a robust, rotationally-moulded polyethylene ocean buoy designed for offshore, port and coastal applications.

The buoy is rotationally-moulded by Sealite from UV-stabilized, virgin polyethylene, and has a 2.2mtr float diameter and 3.2mtr lantern focal height. Lantern focal height may be increased up to 4mtrs.

Built in a 2-part modular design, the buoy can be setup in any IALA recommended assembly, and consists of a high-visibility float section with non-slip tread, and a tower section to support considerable payload.

The twin lifting and mooring eyes are interconnected by stainless steel tie bars through the hull structure – offering enormous strength and superior longevity of the navaid.

Five (5) buoys can be shipped in a 40ft container economically to almost any destination.

The Sealite Nautilus-2200 is one of the largest buoys available to incorporate a one-piece, rotationally-moulded hull section, and represents exceptional value for port operators around the world.
