The GRP (Fibreglass) Thruster Tunnel Ø185mm – Length 750mm is a marine-grade tunnel designed for reliable tunnel thruster installations in both bow and stern applications. Built for strength and long-term durability, it is manufactured using high-quality composite materials to ensure stability inside the hull structure and consistent performance during demanding manoeuvres.
Max Power GRP tunnels are produced using fully isophthalic resin and include a pre-gel coated internal surface, creating a smooth inner finish that supports efficient water flow through the tunnel. An additional first matt coat applied before filament winding allows the tunnel to be cut and drilled safely during installation without damaging the internal gel coat.
This Ø185mm version is a popular choice for stronger thruster setups, providing the perfect balance between structural rigidity and efficient flow.
