Excitation force reducing type ship
Disclosed is an excitation force reducing type ship. An excitation force reducing type ship according to one embodiment of the present invention comprises: a hull having a rear end with a propeller; and an excitation force reducing module which forms an air layer for generating reflected waves on a surface of the hull neighboring the propeller during an operation of the propeller so as to reduce the excitation force in the direction of the hull, wherein the excitation force reducing module can be arranged eccentrically with respect to a center line penetrating through the center of the axis of rotation of the propeller in a vertical direction of the hull..

Apparatus to measure the power expended in propelling a vessel on water
An apparatus is disclosed comprising a suite of sensors for measuring instant static and dynamic pressure, speed of the water flowing past the vessel in the direction of travel of the vessel, acceleration of the vessel in the direction of motion, and position of a vessel, such as a row boat. A microprocessor receives data from the sensors and calculates power expended by the rower, paddler, or other human or non-human power source by finding the total of all forces impinging upon the vessel and passengers, thereafter multiplying by the speed of the water flowing past the vessel in the direction of travel of the vessel.
