Abstract
Apparatuses and methods useful for helping to center watercraft—such as personal watercraft, ski boats, fishing boats, luxury boats, and the like—as they are docked (such as on trailers or watercraft-lifting systems), especially in rough waters and/or strong crosswinds.
Claims28
An apparatus comprising:
- a pair of float arms configured to help center a watercraft having a longitudinal watercraft axis, each float arm having a passageway that is substantially parallel to the longitudinal watercraft axis;
- and
- a frame to which both float arms are pivotally coupled, the frame having a bar to which one of the float arms is pivotally coupled, the bar being long enough for at least two float arms to be pivotally coupled to the bar.
An apparatus comprising:
- a pair of float arms configured to help center a watercraft having a longitudinal watercraft axis, at least one of the float arms having a length and a first structure that is configured to be pivotally coupled to a watercraft docking structure, the first structure being not centered along the length;
- and
- a frame to which both float arms are pivotally coupled, the frame having a bar to which one of the float arms is pivotally coupled, the bar being long enough for at least two float arms to be pivotally coupled to the bar.
An apparatus useful for centering a watercraft, comprising:
- a first float arm having a first float arm length, the first float arm being configured to (a) be pivotally coupled to a watercraft docking structure, and (b) pivot about a first axis that is not centered along the first float arm length;
- and
- a second float arm having a second float arm length, the second float arm being configured to (a) be pivotally coupled to a watercraft docking structure, and (b) pivot about a second axis that is not centered along the second float arm length, the first and second axes being laterally spaced apart from each other;
- where the first and second float arms are configured to be pivotally coupled to a frame that is configured to be pivotally coupled to a trailer.
