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.

A watercraft mounting system that embodies a moving mounting platform and a protective hull cavity which provides protection, prevents damage and improves storage of data collection systems.

The present invention provides a board mountable system for filming underwater video. The inventive board mountable system can be mounted to the underside of water vehicles for incorporating a camera for filming from an underwater perspective. The inventive board mountable system is shaped to minimize drag as a result of the mounted camera or camera system. Embodiments of the inventive system includes a fin shaped housing for holding a camera or camera system. In certain embodiments, the fin is removably attached to the water vehicle, such as a surf board, where the fin housing can be swapped with other fins being used with the water vehicle for controlling the direction of a watersports board in motion. These embodiments of the inventive system further include a connection means for connecting the fin to the underside of a water vessel.

Apparatus and means are provided for elevating a video camera above the deck of a vessel in order to achieve a better and more distant view of objects below the surface of the water. The apparatus provides for allowing a video camera to be elevated, aimed in any horizontal direction, and further tilted from substantially straight down into the water to substantially straight up into the sky. The apparatus further provides for such a tower of fixed elevation or one which may be adjustable and elevation. Further it provides for either manual or remote adjustment of the horizontal direction, vertical tilt, elevation, or for the zoom or aperture of the video camera. It also provides for viewing the image either on one or more fixed video monitors or upon the screen of a computing device, such as a smart phone, tablet, or any form of computer which are adapted with any form of wireless, such as Wi-Fi or Bluetooth.

The present invention refers to a hybrid vessel with a ballast system in which the position of the cabin (102) is changed vertically, from emerged to submerged and vice versa, according to the decision of its operator.

Thus, the present invention describes a hybrid vessel with ballast water system comprising at least one cabin (102) and at least one main tank (101) of ballast water, and the tank (101) is connected directly to the CAB (102) or partially above the water level.

An inflatable hand-held snorkeling float supports a see-through underwater viewing module having a top glass and a bottom glass joined by a collapsible sidewall. A pneumatic chamber surrounds the viewing module. The chamber has a top deck and a bottom deck symmetrically pitched about a central longitudinal axis to form a wedge-shape having an included angle between about 5° and 15°. The top and bottom glasses are also wedge-shaped symmetrically about the longitudinal axis. Handles extend from the sides of the chamber, and are generally centered along a central transverse axis. An optional accessory mount may be affixed to one of the decks adjacent the bow. The accessory mount can be configured with a pair of dedicated connection pads to hold a dive flag and a camera, or two cameras, etc. The configuration of the float provides flotation symmetry when roll-inverted but flotation asymmetry when pitch-inverted.
