Described herein are examples of buoyancy supplements. A buoyancy supplement may include a system including a front flotation portion including a front deck having a front surface, a rear flotation portion including a rear deck having a rear surface. One or both front and rear surfaces having an accessory attachment point, a through-hole substantially parallel to the front or rear surface, a mounting apparatus, a tie-down anchor, and a first and second runner each having a first end configured to attach to the front flotation portion and a second end configured to attach to the rear flotation portion. The front flotation portion and the rear flotation portion may be configured to attach to a float tube.

A floating dock system can include a base portion, a cradle, at least one guide assembly, and a lift assembly. The base portion can include a lateral deck portion extending along a first plane and defining a boat slip, and at least one float element configured to provide a float element buoyancy force sufficient to maintain at least part of the deck portion above the water surface. The can include a lateral upper portion extending along a second plane, and a support structure configured to support the nautical vessel. A guide can include male and female guide portions. A lift assembly can include a motor configured to move the cradle between upper and lower positions.

A system and method in which a buoyant central docking station captures, lifts and couples one or more other sea vessels is disclosed, wherein a flexible, modularized production system is quickly realized on a cost effective basis. The capabilities of a number of older, less expensive, readily available vessels are combined to achieve an effective FPSO substitute that allows lower producing fields to be explored and produced in a profitable manner. The time horizon between initiation and consummation of field operations is reduced, and older vessels that might otherwise be scrapped or retired are again made useful and seaworthy in a safe and profitable exploration and production environment.

A pile guide has a collar with a void therein. A planar flange extends from a side of the collar. A bracket has opposing guides constructed and arranged for receiving the planar flange of the pile guide therein. The planar flange is in a slidable relationship with the bracket, and the bracket is constructed and arranged for mounting to a floating dock. The distance of the collar from the floating dock can be adjusted to accommodate for distances of piles from the floating dock.

A buoyancy tank for a portable floatation apparatus which allows for the elevation of a watercraft above a water-line and which allows for the removal of the watercraft from a body of water. The buoyancy tank has at least one and/or a plurality of integrated cylindrical structures which supports the floatation apparatus in transport and storage. The integrated cylindrical structures provide sufficient support to allow the removal of the floatation apparatus by use of a boat lift and further provide sufficient support to allow a watercraft to be stacked on top of the floating apparatus while the floating apparatus is stacked on top of the floating apparatus for the purposes of storage. A plurality of said buoyancy tanks may be connected to the portable floatation apparatus by use of connecting means. The portable floatation apparatus should have a pumping device which pumps a sufficient volume of air into a plurality of the buoyancy tank which is effective to selectively and conveniently elevate a watercraft above a water line.
