Abstract
A shallow water anchoring mechanism for a vessel drives an upper arm between a raised position, in which the lower end of a pole is above the bottom of the hull and a lowered position, in which the lower end of the pole extends downward below the vessel so as to engage the bottom of a shallow body of water. This provides a shallow-water anchoring arrangement for a boat that does a minimum amount of damage to sea life, including oysters, and grasses or other vegetation growing on the bottom of the water, and allows a boater to anchor in shallow water and to leave the anchorage without bringing mud, grasses, or other debris into the boat. A manual disconnect arrangement allows the boater to pull the pole out of the water in the event of actuator or power supply failure.
Claims14
Apparatus for anchoring a vessel to a bottom of a body of water, the apparatus comprising:
- an upper arm having a proximal end and a distal end, the proximal end of the upper arm attached to a hull of the boat, the proximal end of the arm comprising hinged attachment means whereby the upper arm is adapted to move between a raised position and a lowered position;
- a lower arm having a proximal end attached to the upper arm adjacent the distal end thereof, the lower arm having a distal end adapted to engage the bottom when the upper arm is in the lowered position;
- an actuator adapted to move the upper arm between the raised and the lowered positions;
- and
- means for partially disassembling the apparatus without the use of tools.
Apparatus for anchoring a vessel to a bottom of a body of water, the apparatus comprising:
- an upper arm comprising at least four members forming a parallelogram having two elongate sides and two shorter sides, wherein each of the members forming one of the elongate sides is pivotally connected adjacent each of its two ends to a respective one of the shorter sides, and wherein a first of the two shorter sides is fixedly attached to a hull of the vessel so that the upper arm is adapted to move in a vertical plane between a raised and a lowered position;
- a lower arm attached to the second of the two shorter sides of the upper arm;
- an actuator having a variable length portion, the actuator extending between the two shorter sides of the upper arm, the actuator pivotally attached adjacent each of two ends thereof to a respective one of the two shorter sides so that the actuator is adapted to move the upper arm between the raised and the lowered position when the length of the variable length portion of the actuator is changed.
