  • Mast stabilizing device
    Patent number: 9233733
    Abstract: Some implementations feature a mast stabilizing device that includes a mast comprising a first portion and a second portion, a sensor coupled to the first portion of the mast, and a pivot structure coupled to the mast. The pivot structure is configured to allow the mast to pivot in the mast stabilizing device. The mast is coupled to the pivot structure so as to pivot along a pivot portion of the mast. The mast stabilizing device also includes a mass coupled to the second portion of the mast. The mass is configured to counteract a force applied to the first portion of the mast. The mast stabilizing device further includes a platform coupled to the pivot structure, the platform configured to operate on a body of water. In some implementations, the pivot structure is a gimbal device.
