Typically pleasure crafts over 35' will have a bow thruster installed on the boat. Bow thrusters help maneuver your boat like a car. Bow thrusters are made for boats 20' to super sized mega yachts.
Choosing the right bow thruster for your boat is key to getting the most out of your product. Some custom built or very high end boats may have a high power bow thruster that pushes the bow against a direct sidewind of 24-26 knots. The thruster’s performance on a boat is basically determined by the boat’s wind area, the wind area distribution and the thruster’s tunnel position in the hull. By knowing these factors we can calculate the wind pressure on the boat and the center point of this wind pressure. From these calculations we can determine what thrust is needed to counter the wind pressure with the given bow thruster position. The boat weight is normally not a major factor for most pleasure craft.
Conclusion
*The two main factors* that decide correct bow thruster sizing are:
- boat owner performance requirements
- boat size, type and shape
