A system is proposed for putting boats on hold when they are afloat on a water body after they have been launched and/or before they are hauled out of the water. The system for putting on hold includes: a floating device, having a central floating element and secondary elements extending from the central floating element. Each secondary element being associated with a reception place and having at least one point for driving, by thrust or traction, a boat positioned in an associated reception place. A system for moving is adapted to moving the secondary elements around the central floating element and, via the points for driving, moving the boats that are positioned in the reception places.

The invention is a base module for a starting apparatus of sport-purpose flatwater boat competitions, comprising a longitudinal holder arranged crosswise to the direction of motion of the boats, a level adjustment unit, a dynamic stabilizer, and a remote controlled start permitting unit having a mechanical drive unit. According to the invention, the longitudinal holder (2) is made of one or more rigid, hollow pipe or profiled bar.

Conventional ship launching airbags are made of several layers of rubber and fiber meshes bonded together by vulcanization. With the existing fabrication process, an airbag is strong in standing heavy pressure at its surfaces, but weak against the cutting by sharp edges of metal debris or oyster shells. An airbag's functional failure during a field operation can cause not only stoppage, but also explosion, hence a serious safety hazard. To overcome such structural weakness, a new type of airbags with anti-cutting capability is disclosed in which a conventional ship launching airbag is covered with a layer of anti-cutting armor made of steel cord ply sheets, a standard off-the-shelf product for the making of tires, embedded at the surface of the airbag's main body.

A kayak launching system provides a vertical support pole and submersible rack arms extending out from a dock beneath the water. The rack arms may be lowered to allow a kayak to be positioned above them and then raised to stabilize the kayak during entrance or exit.
