The Sleipner GRP Bow Thruster Tunnel 185 × 6 × 1750 mm is a high‑quality glass‑reinforced polyester (GRP) tunnel designed to house a bow‑thruster installation in the hull of a boat. Crafted with a 6 mm wall thickness and an internal diameter of 185 mm, this tunnel provides a robust, structurally sound conduit for thruster propellers and drive legs, while ensuring a smooth and streamlined internal bore for efficient water flow.
Constructed from longitudinal and cross‑woven GRP gives the tunnel strong mechanical integrity, high resistance to osmosis, and long‑term durability in the marine environment — ideal for saltwater exposure and repeated usage.
