Craftsman marine bow tunnel

Description

Craftsman Marine supplies bow tunnels in different lengths and diameters. The diameter of the tunnel depends on the chosen thruster.

Tunnels are made from GRV (glassfiber reinforced vinylester).
Glassfiber reinforced polylester filled with PU foam

Because of this choice, they not only look good but also help reduce noise.

The large radius at the tunnel ends reduces turbulence at high speeds.

Shallow draft vessels can still use the stern tunnel but need an additional deflector kit. These covers are mounted on the tunnel and minimize the amount of false air being sucked into the tunnel.The waterflow out of the tunnel is slightly deflected downwards to have maximum effect
