Vetus GRP Tunnel 125 x 1000mm

The Vetus GRP Tunnel 125 x 1000mm is a fiberglass-reinforced plastic (GRP) thruster tunnel designed for marine propulsion systems requiring a 125mm diameter opening. This component serves as a protective and structural conduit for bow and stern thrusters, enabling efficient water passage while maintaining hull integrity. Marine engineers and boat builders rely on this tunnel to streamline thruster installation and optimize performance in both commercial and recreational vessel applications.

Constructed from durable GRP material, the Vetus tunnel offers superior corrosion resistance and lightweight performance compared to traditional metal alternatives, making it ideal for saltwater and freshwater environments. The 1000mm length accommodates standard hull thicknesses while the 125mm diameter specification ensures compatibility with mid-range thruster units. GRP construction delivers exceptional structural rigidity and longevity without the weight penalty of steel, reducing overall vessel displacement and fuel consumption while maintaining full strength under dynamic water pressure and operational stresses.

Marine technicians, shipyard professionals, and boat restoration specialists benefit most from this tunnel's proven reliability in retrofit and new-build applications. The standardized 125mm diameter aligns with VETUS thruster systems and compatible OEM units, simplifying procurement and installation logistics. Weight savings of approximately 8.4 pounds per unit contribute meaningfully to overall vessel performance, particularly on smaller craft where every pound impacts speed and fuel efficiency. Installation requires standard marine sealants and fastening systems, with the GRP surface accepting paint and anti-fouling coatings for long-term protection and aesthetic integration.
