Disclosed is a boat including a bottom bordered radially externally by a wall which includes an inflatable and foldable front wall, an inflatable and foldable side wall, and a rear wall. The boat includes at least one inflatable and foldable longitudinal support parallel to the side wall, the support including an inflatable tube and a foldable upper connection which connects the tube to the upper part of the side wall, the upper connection extending longitudinally along the side wall and forming during use a surface P capable of receiving an element.

A rigid-inflatable boat (RIB) includes a solid hull and an inflatable tube, forming a part of a gunwale. The boat includes a tube air filling system with an air conduit arranged to communicate with air pumping system and a tube, where the air conduit extends along at least a portion of the tube. The solid hull includes a gunwale portion, forming a part of the gunwale, where the air conduit is enclosed in the gunwale portion.

A marine surface vessel includes a boarding pole for maritime boarding actions and the boarding pole is at a first end of the boarding pole, attached to a deck of the vessel via a flexible joint. The vessel includes a holding device presenting, or being arranged to present, a holding cavity arranged to receive, in a non-erected condition of the boarding pole, a boarding engagement device at a second end of the boarding pole, which second end is opposite to the first end.

Inflatable device pressure gauge apparatus and methods are described. According to one aspect, an inflatable device pressure gauge apparatus includes a housing, an attachment mechanism configured to attach the pressure gauge apparatus to an inflatable device which comprises an air chamber which is configured to be inflated to an increased pressure above atmospheric pressure during use of the inflatable device, a pressure sensor coupled with the housing and configured to sense pressurized air from the air chamber of the inflatable device and to output a signal corresponding to an air pressure within the air chamber, a processor configured to process the signal from the pressure sensor and to control generation of a user perceptible emission regarding the air pressure of the air chamber as a result of the processing of the signal, and a power source coupled with the housing and configured to provide electrical energy to the processor.

The towable device having a cover and looped tow strap includes one or more toroidal inflatable tubes surrounded by an abrasion and puncture resistant cover. The cover tightly wraps around the inflated tube(s) to support and contain the tube(s). A top surface of the cover defines openings around the central passageway created by each toroidal tube to allow a rider to enter and occupy the space within the passageway. A lower surface of the cover provides a continuous surface to accommodate sliding during use and support a rider positioned within the center of each tube. A tow strap wraps around a circumference of at least one of the tubes within the cover and extends out a front of the cover for attachment to a towing device.

A saddle for an aquatic board is disclosed. The saddle is equipped with a strap or straps and/or edge wise clamps, or other suitably firm fastener, to engage and maintain position on the aquatic board positioned beneath the saddle. A user can then stand on the board and squeeze the saddle between their knees and ankles and maintain an enhanced balance on the board or, if fatigued, can sit or kneel alongside or on the saddle and paddle/ride from a seated or kneeling position. The saddle may be inflatable or solid and may include an inner void for storage for personal effects or equipment. The saddle may further include a speaker, cup holder, handles, or other optional features.

A portable air-cushion bag comprising an air cushion and a bag body, wherein the air cushion is fixed with the bag body, and a storage space with an opening is formed by the air cushion and the bag body. The air cushion is provided with an inflation port for facilitating air inflation and deflation. The edges of the air cushion are sealed, and the air cushion is internally provided with a containing space for containing air. A water-permeable structure is arranged at one end of the bag body, which is far away from the opening of the storage space. When the inflatable boat isn't used anymore, it is deflated, folded, and placed into the storage space, thus achieving a storing function of the air-cushion bag. The inflatable boat may be inflated by using the air-cushion bag instead of an air pump or other inflation equipment, which greatly eases the storage and carrying.

An inflatable slide may comprise a ramp portion and a slide portion extending from the ramp portion. A multipurpose indicator tube may be fluidly coupled to the slide portion. A releasable restraint may be disposed between the multipurpose indicator tube and the slide portion. The releasable restraint may comprise a first restraint portion coupled to an end of the multipurpose indicator tube and a second restraint portion coupled to a toe end of the slide portion. The first restraint portion may be releasably coupled to the second restraint portion. A detachable restraint may be coupled to the slide portion and configured to detachably couple to the end of the multipurpose indicator tube.

A mounting assembly for an outrigger. The mounting assembly includes a mounting body adapted to be received by a tube and pivotably couple to a mounting point. The mounting body includes a slotted opening adapted to receive a fastener to restrict axial movement of the mounting body relative to the tube and permit rotational movement of the tube relative to the mounting body.

An inflatable motor boat refers to water vehicles, in particular, to inflatable boats with outboard engines operating in low water conditions. The problem to which the invention is directed, is to improve the performance parameters of inflatable motor boats, The technical result of the claimed invention is the possibility of high-performance boating in low and extreme low depth conditions at different speeds due to the presence of the inclined longitudinal tunnel, with some configuring details in different versions, which allows to improve the water supply to the propellers of outboard engines or, in the case of water jet engines, to their water jet inlets, to optimize their location and eliminate the risk of damage thereof. The claimed technical result is achieved by the fact that the invention is an inflatable motor boat with a U-shaped hull in plan view. The hull of the inflatable motor boat is formed by open outline of inflatable boards and bow part. An inflatable bottom is attached to the hull, which bottom is divided into at least three longitudinal segments. A longitudinal tunnel is made in the middle segment of the bottom, the inner surface of which tunnel has essentially arc-shaped form. The tunnel comprises a portion having a wedge-shaped form in a vertical section, wherein the angle of inclination of the portion relative to the water surface plane is from 5 to 45. The tunnel can also comprise an additional portion with an angle of inclination from 0 to 20 relative to the water surface plane, wherein the length of the additional portion is less than the length of the wedge-shaped portion.
