Sleipner Tunnel for Bow Thruster – GRP 185 x 6 x 2500mm 9025

The GRP Bow Thruster Tunnel 185 × 6 × 2500 mm is engineered for marine professionals seeking a durable, corrosion-resistant, and high-performance solution for bow thruster installations. Constructed from premium Glass Reinforced Plastic (GRP), this tunnel combines exceptional structural strength with a lightweight design, making it easier to install while maintaining long-term reliability in harsh marine environments.

With a 6 mm wall thickness and 185 mm internal diameter, the tunnel ensures perfect compatibility with bow thruster systems designed for this size class. Its extended 2500 mm length provides ample installation flexibility, especially for vessels requiring deeper or more customized hull integrations. The smooth interior surface maximizes hydrodynamic efficiency, reducing turbulence and improving thrust output for better handling during docking and low-speed maneuvers.

This GRP tunnel is ideal for new builds, refits, and performance upgrades across a wide variety of vessels, including commercial craft, motorboats, and sailboats. Unlike steel tunnels, GRP eliminates corrosion concerns, minimizes maintenance requirements, and avoids adding unnecessary weight to the vessel’s bow.
