Automatic watercraft cover

A watercraft covering apparatus attachable to a watercraft lift frame having a first upright member and a second upright member spaced apart from the first upright member, and adapted for supporting a watercraft having a watercraft first end portion and a watercraft second end portion, and watercraft lateral sides, the watercraft covering apparatus comprising:

• at least one mechanism base with a mechanism first end portion and a mechanism second end portion, the mechanism base being located outboard of at least one of the watercraft lateral sides when the watercraft is supported by the frame, the mechanism first end portion being connectable to the first upright member and the mechanism second end being connectable to the second upright member;
• at least one swing arm having a swing arm lower end portion pivotally attached to the mechanism base and a swing arm upper end portion, the swing arm having a swing arm longitudinal slot, the swing arm being pivotable between a swing arm first position whereat the swing arm upper end portion is positioned proximate to the watercraft first end portion when the watercraft is supported by the frame and a swing arm second position whereat the swing arm upper end portion is positioned proximate to the watercraft second end when the watercraft is supported by the frame, when in the swing arm second position the swing arm is more than 140 degrees from the swing arm when in the swing arm first position;
• a driving pin connected to the swing arm longitudinal slot;
• a follower member with a follower member lower end portion pivotally connected to the mechanism base and a follower member upper end portion connected to the driving pin such that when the follower member is in a follower member first position the swing arm is in the swing arm first position, and when the follower member is in a follower member second position the swing arm is in the swing arm second position;
• at least one actuation member having an actuation member first end portion pivotally connected to the mechanism base and an actuation member second end portion connected to the follower member;
• an elongated roller having an end portion rotatably supported by the swing arm upper end portion for travel with the swing arm upper end portion as the swing arm is pivotally moved between the swing arm first position and the swing arm second position;
• a watercraft cover with a watercraft cover first end and a watercraft cover second end, the cover first end being attached to a securing member, and the cover second end being attached to the elongated roller, the watercraft cover being substantially fully wound about the elongated roller when the swing arm is in the swing arm first position, the watercraft cover being sized to lengthwise extend over and cover the watercraft when the swing arm is move to the swing arm second position and the watercraft is supported by the frame;
• and
• a torsion member configured so that the elongated roller is rotated in a first rotational direction when the swing arm is moved to the swing arm first position and rotated in the opposite rotational direction when the swing arm is moved to the swing arm second position, the torsion member providing sufficient torque to roll the cover on the elongated roller.
