Benefits of technology
The patent text is about a design for a trim tab member, which is a part of a ship's propulsion system. The design includes a groove on the bottom of the trim tab member that guides the movement of water along the bottom of the tab member caused by the ship's movement. The groove is wider front to back, but narrower towards the back, which speeds up the water flow and helps the ship move more effectively.
Problems solved by technology
However, in the case of a ship such as a power boat, hull trim occurs due to a linear characteristic of the boat, and excessive trim causes performance reduction of the ship and a safety problem related to an unexpected accident of a sailor.
Particularly, a risk of a rollover accident of a ship is generated due to lateral rolling, which occurs when the power boat is steered, and a performance reduction problem occurs due to resistance generated due to the rolling.
However, since a sailor of a boat should manually operate the conventional trim tab, in a case in which the sailor is an amateur, there is a disadvantage in that it is difficult to properly operate the trim tab according to hull rolling of a ship.
