Abstract

The floating drive-on docking system for a watercraft uses a main floatation portion where the watercraft rests when loaded and a pivoting entry portion for creating a low loading angle between the watercraft and the floating drive-on docking system, resulting in only a small amount of propulsion from the watercraft being required to load onto the docking system. The pivoting entry portion has entry features, either rollers or raised bumps, that remain above the waterline when not engaged by the watercraft to keep the loading surfaces free from marine growth that can harm the hull of a watercraft. Wide side guides on the pivoting entry portion assist in positioning the craft for loading onto the docking system.

Claims

1. A floating drive-on docking system for a watercraft having a hull, comprising:

at least one main floatation portion comprised of at least one buoyant pontoon; and

at least one entry portion wherein the entry portion is pivotally attached to the main floatation portion, the pivoting entry portion having at least one entry feature configured to be engaged by the watercraft hull upon initiation of loading of the watercraft onto the floating drive-on docking system prior to the watercraft engaging the main floatation portion, the pivoting entry portion being configured to automatically self position itself with the at least one entry feature held above the waterline when not engaged by the watercraft hull, and when engaged by the watercraft hull upon initiation of loading of the watercraft onto the floating drive-on docking system to automatically pivot downward and move the at least one entry feature to a position below the waterline in response to the force applied to the at least one feature by the watercraft hull without application of additional force being applied to the pivoting entry portion and with the pivoting entry portion being moved to a position with an upward incline relative to the main floatation portion which facilitates receiving the watercraft hull on the pivoting entry portion and subsequent forward movement of the watercraft hull onto the main floatation portion.
