Increased energy harvesting is realized using a nonlinear buoy geometry for reactive power generation. By exploiting the nonlinear dynamic coupling between the buoy geometry and the potential wideband frequency spectrum of incoming waves in the controller/buoy design, increased power can be captured in comparison to conventional wave energy converter designs. In particular, the reactive power and energy storage system requirements are inherently embedded in the nonlinear buoy geometry, therefore requiring only simple rate-feedback control.

A portable basket is used to collect multiple weighted lines that extend between a buoy and a submerged crab pot. The basket is a cylindrical structure with flexible sidewalls that extend from a top edge to a bottom panel. Attached to the inside surface of the basket near the top edge are at least two ring connectors. During use, the basket is positioned below a winch system to pull the weighted line and the crab pot out of the water. The weighted line's first connector is detached from the buoy and connected to a ring connector inside the basket. The winch is then activated to allow the weighted line to fall into the basket and get automatically stacked in a vertical coil configuration inside the basket. When the crab pot is lifted out of the water, the second connector is detached from the crab pot and attached to the second ring connector near the top edge. The process may be repeated to collect additional weighted lines. When setting a crab pot, the buoy and pot connectors from one weighted line are detached from the ring connector and attached to desired buoy and pot, respectively. The buoy, the pot, and the coiled weighted line can then be deposited into the water.

Devices, buoys, kits, systems and methods for preventing small objects, such as but not limited to portable phones, money and keys from sinking in the water. A foam block buoy molded about a t-shaped plastic insert with an eyelet in a stem extending therefrom for attaching to a tether line. A phone foldable ring stand can be included with a peel and stick backing for being attached to a portable phone, that is attachable to the end of the tether line, wherein the float prevents the portable phone from sinking and becoming lost in water. A dry bag can be included to also be attachable to the tether line for keeping items from becoming wet and damaged. Additionally, a battery powered fishing lure, can be attached to the float or the line to allow the float buoy to be found in the dark.
