04In service
The same hull works for a rescue crew at speed, a dive club, a family day out and a cargo run. Each is specified for the job it has to do, and comes back looking much as it went out.
05Manufacture
Powdered polyethylene is loaded into a heated mould that turns on two axes until the material fuses into one seamless, hollow shell. Nothing is bonded, bolted or laminated.
Powdered polyethylene, UV-stabilised and pigmented right through.
The charged mould enters the oven.
It turns on two axes at once, so the melt coats every surface evenly.
Three layers fuse into one wall. No join, no weak point.
Controlled cooling sets the form and locks in the structure.
The shell leaves the mould finished. No gelcoat, no lay-up, no filler.
06The material
Beach launches, pontoon knocks and rescue work leave scuffs rather than cracks. Bending begins only at 200 kg per 1.56 dm².
Polyethylene is less dense than water, so buoyancy is a property of the hull itself — not of added foam or air chambers.
UV-stabilised and chemically inert. No annual gelcoat work, no osmosis, no repainting. Wash it down and go back out.
Moulding uses less material than laminating. A Hydra 450 weighs 298 kg, so a modest outboard delivers real performance.
Water that comes aboard leaves on its own. Combined with the moulded hull, this is why the range is specified for rescue and patrol.
One material, no composites, no resins. At the end of its service life the whole hull can be reprocessed.
