Significantly lower installed cost, more responsive performance, no mounting holes below the waterline, virtually silent operation. These are only a few of the many benefits you receive when choosing a Sideshift thruster over conventional thruster systems.
Although occasionally found on smaller boats (less than 30′ in length), through-the-hull or tunnel-style thrusters are usually found on larger boats. While they are generally installed as a factory option, tunnel thrusters can be added as an after-market product. There is, however, a downside to retrofitting.
First, two large holes must be cut or drilled on either side of the hull below the water line for the tunnel/tube to be passed through the boat. Correct tunnel placement is critical and requires a skilled installer experienced in structural fiberglass repairs, because the area around the tunnel on the hull’s exterior will require fiberglass work, paint and gelcoat. It’s not uncommon for a through-the-hull thruster to experience leakage over time that can void the boat owners hull warranty. In addition, because of the structural work required, the total installed cost of a tunnel-type thruster is typically more than double that of a Sideshift external thruster system. The placement of the tunnel and the thruster motor will also reduce storage space inside the boat and/or interfere with tanks, bulkheads and other structural components. Also, in order to be effective the thruster must be placed as far forward as possible and deep enough below the water line to generate the maximum turning moment – something that is not always practical with many tunnel thrusters. Finally, through-the-hull thrusters are known to generate a fair amount of noise and vibration when operating.
Sideshift invented the original externally mounted bow thruster. Choosing a Sideshift bow or stern thruster offers numerous advantages over traditional tunnel-style thrusters. Significantly lower installed costs. More responsive performance. No mounting holes below the waterline. Virtually silent operation. These are only a few of the many benefits you receive when choosing a Sideshift thruster over conventional tunnel thruster systems.
