Abstract: A vessel for towing another vessel comprises a hull, a tow cable coupled to the hull, a hook having a first leg fixed to a free end of the cable, a second leg including a free end and a hook bottom. The first and second legs form an opening for receiving a rope located at the vessel and launched from another vessel. The first and second legs extend in a main plane. A rope positioning system positions a rope and a hook support for the hook with respect to each other such that the rope extends in transverse direction of the main plane at the opening of the hook when the hook is linked to the hook support. A rope pressing system presses the rope the hook towards the hook bottom when the hook is linked to the hook support, creating a clamping force between the legs and the rope.

Abstract: A decoy assembly is configured to have an adjustable buoyancy level. The decoy assembly has a head assembly with a decoy head. A decoy body has a body planar bottom surface and a head opening configured to accommodate the head assembly. The head assembly further has a head keel bracket, joined to the planar bottom surface. A head weight is joined to the head keel bracket and configured to lower a head assembly center of gravity. The decoy assembly has body keel brackets and body keel weights joined to the body keel bracket at the planar bottom surface and configured to lower the body assembly center of gravity. Adjusting the body assembly center of gravity independently of the head assembly center of gravity provides lifelike movement for the decoy assembly and allows the orientation of the decoy to be varied for a natural looking presentation.

Abstract: A decoy for luring waterfowl has a body that has an upper reservoir partially filled with water. A neck is partially submerged in the upper reservoir. A head, is attached to the neck and configured to raise a neck center of gravity and lower a neck center of buoyancy. Wherein the neck is configured to rotate within the upper reservoir.
