摘要

To prevent having a side surface of a mounted boat stored by a boat davit pushed more than necessary to a cradle.SOLUTION: A boat davit includes: a first boat supporting arm and a second boat supporting arm provided with pulleys on tips and built separately from each other on a deck; a first wire for moving through the pulleys; a winch for operating the first wire; and a cradle provided with a first fitting block capable of having the first wire and a second wire attached and a second fitting block capable of having the first wire and the second wire attached, and moving along the first boat supporting arm and the second boat supporting arm. In addition, a horizontal position of a mounted boat is retained by engaging one end of a first supporting member to a first fixture, engaging the other end of the first supporting member to the cradle, engaging one end of a second supporting member to a second fixture, and engaging the other end of the second supporting member to the cradle.SELECTED DRAWING: Figure 4
