The present invention provides a joining structure with a joining strength higher than that of a conventional rubber core cord joining structure of a rubber ring. The invention also provides a solidifying agent for joining a rubber core cord that provides such a joining structure. A joining structure 2 of a rubber core cord 11 according to the present invention is a rubber core cord joining structure of which opposite end portions of the rubber core cord 11 or end portions of two rubber core cords are joined to each other with an adhesive. A solidified portion 23 formed by a solidifying agent 25 that has solidified is formed at each of the opposite end portions of the rubber core cord 11 or each of the end portions of the two rubber core cords, and the solidified portion 23 contains porous particles. The solidifying agent 25 according to the present invention is a solidifying agent that is applied to the rubber core cord 11, and contains a solvent containing a solidification component and porous particles contained in the solvent.

A watercraft leash assembly has a leash cord construction comprising an elongate, elastomeric cord body having a reinforcing element embedded therein. The reinforcing element may comprise a co-extruded filament which is helical or other non-linear shape when the leash cord is in a non-extended condition, and which straightens as the leash cord extends.

A leash assembly (110) for watercraft users with an elongate composite horn (112) and extended base (128) providing a superior stand-off distance for the leash cord. In addition, an over-braided sheathed cord (114) provides substantial improvements in use with respect to elongation, strength and tangling. The leash assembly (110) may also feature a low hydrodynamic drag rail saver, non-slip arrangement for the cuff (116) and a unique pull tab (119) release for the cuff (116).

An elongate, flexible line for providing a linkage between a first structure and a second structure. The line may be a mooring line. It has a braided tubular sheath, the sheath being able to change reversibly and repeatedly in length and its braided structure being such that an increase in sheath length is accompanied by a lateral dimensional decrease. Within the sheath is an impervious flexible bladder. The bladder defines a fluid-containing internal chamber which is acted on by the sheath so that the volume of the chamber varies with the sheath length. A pressure source arranged to pressurise the chamber. A restricted passage communicates with the chamber.

The pressurised bladder urges the sheath to expand laterally and to contract. An increase in sheath extension causes fluid to be exhausted from the chamber through the restriction, increasing chamber pressure and providing a damping force opposed to the sheath's extension.

An improved top down furling system includes one or more improved components. A lower rotary drive unit with a rotary tack swivel rotates against a fixed portion of the furler, or is configured to permit routing of the tack line below the unit. The system may include an anti-torsion cable constructed in a manner so as to be able to transmit torque without excessive tension applied to the cable. The system also may include an end terminal of the anti-torsion cable having a quick side mount or bayonet type connection to the rotary drive unit.
