Sleipner Tunnel for Bow Thruster – GRP 185 x 6 x 850mm 8025

The GRP Bow Thruster Tunnel 185 × 6 × 850 mm is engineered for reliability, strength, and efficient integration into a wide range of marine vessels. Constructed from high-quality Glass Reinforced Plastic (GRP), this tunnel provides excellent durability while maintaining a lightweight structure that simplifies installation and reduces overall vessel weight.

With a 6 mm wall thickness and an internal diameter of 185 mm, the tunnel ensures precise compatibility with bow thrusters designed for Ø185 mm systems. Its 850 mm length makes it ideal for vessels requiring a compact yet robust thruster tunnel solution—perfect for new builds, refits, and performance upgrades.

GRP construction offers significant advantages over steel alternatives, including complete corrosion resistance and minimal maintenance requirements. The tunnel’s smooth internal surface improves hydrodynamic flow, supporting efficient thrust output and enhanced manoeuvrability in tight docking situations or low-speed operations.

Suitable for commercial vessels, motorboats, and sailboats, this tunnel provides dependable performance in demanding marine environments.
