Marine vehicle with thrust boosting device

摘要

A marine vehicle (200) includes a hull (210), a propeller (201), anda thrust boosting device (2) mounted to the hull (210) and disposed forwardly of the propeller (201). The thrust boosting device (2) includes first, second and third fin members (21, 22, 23) extending radially with respect to a rotational axis (L) of the propeller (201). The first, second and third fin members (21, 22, 23) form first, second and third angles (θ1, θ2, θ3) with a reference line (S) that extends upwardly from and that is perpendicular to the rotational axis (L), respectively. The first angle (θ1) ranges between 70 and 110°, the second angle (θ2) ranges between 225° and 255°, and the third angle (θ3) ranges between 285° and 315°.
