Abstract: Embodiments are directed to rod tip guides. A rod tip guide may comprise a ring body, a rod tube, a foot, and a leg. The rod tube may be mechanically coupled to the ring body and configured to receive a tip end portion of a rod. The foot may be configured to be mechanically coupled to a circumferential surface of the rod when the tip end portion of the rod is received in the rod tube. The leg may have a proximal end portion and a distal end portion. The proximal end portion of the leg may be mechanically coupled to the ring body, the distal end portion of the leg may be mechanically coupled to the foot, and the leg may be configured to maintain a separation space between the rod tube and the foot when the tip end portion of the rod is received in the rod tube.
Abstract: This invention is type of dual-purpose boat, including cabin and hull. This boat is unique in that between the cabin and hull there is a lifting mechanism connecting the hull and cabin, at least one of which has been set up with a buoyancy regulating structure. This invention can be used as a regular boat, or if the cabin is lowered, this invention becomes a semi-submerged vessel that can be used for operational purposes or underwater sightseeing. When the invention enters shallow water or needs to navigate at high speed, the cabin can be raised to prevent beaching and to reduce resistance. The operation of this invention is simple and expands the single function of current boats.
