Tunnel bow thrusters are highly cost effective and easy to fit on many boat types. Tunnel thrusters offer an ideal solution for motor boats and even deep-footed sailing yachts when sailing performance is not paramount.Performance data is given for a thruster installed at an immersion depth of one tunnel’s diameter, in a tunnel no longer than twice the tunnel’s diameter, and this within a variation of + / - 6%. Longer tunnels will result in lower thrust ratings and higher power consumption.
