GRP tunnels are available in several lengths for each thruster model.
They are purpose-built for our thrusters and provide ultimate strength, accuracy and osmosis protection to ensure an easy and safe thruster installation.
The wall thickness is adapted to each thruster’s power and boat size.
Unlike most other thruster tubes, they are not just spun with a single thread, but in fact, contains several layers of full rowing mat.
