Improvement of knowledge of fishing boat operations : Influences of ship bottom attachment of barnacles and seaweeds

On board research were carried out for investigate the quality of fishing boat under the circumstances, which are observed experimentally in ordinary use on the seas. The present research was prepared in the ordinary operation of maintenances in dock. As the results, it was revealed that fuel consumption was reduced remarkably by cleaning bottom of ship hull, propeller and rudder. And in the condition of foul of ship bottom before cleaning, reducing the rotation speed of the main engine capable of largely improving a fuel efficiency, in comparison to the rate of decrease in ship speed.
