Abstract: A flotation device for providing emergency flotation for a person swimming or passing through a body of water, comprising a container filled with a charge of a gaseous material under a pressure such that it is in its liquid phase at normal environmental temperatures. The container is connected to a flexible flotation chamber through a passage which remains normally closed until actuated by the user. When the device is actuated by opening the passage, the charge expands into the flotation chamber, thereby inflating it, and providing support to the user in the water. The gaseous material has thermodynamic properties such that it remains in its liquid phase right up to the maximum temperatures to which the device is expected to be exposed to. Consequently, its volume, and hence the internal pressure within the gas container, does not increase significantly, thereby enabling the container to be of lightweight construction.

A propulsor is pivotally coupled to the base and pivotable into and between a deployed position and a stowed position. The propulsor is configured to propel the marine vessel in water when in the deployed position. A lock device has a rigid member and is selectively engageable such that the rigid member prevents the propulsor from pivoting away from the stowed position.

Abstract: An oarlock that is designed to be used with an oar-right. It is an oarlock that has a pin for securing the oarlock in an oar holder or gunwale of a boat. A U-shaped bracket is attached to the pin. There is a formed piece that has a cylindrical upper portion and a lower squared portion that is secured to the U-shaped bracket. An oar fits into the cylindrical upper portion and the oar-right fits into the lower squared portion of the formed member. The U-shaped bracket can rotate on the pin, which means that the oarlock can rotate 360 degrees and the formed member is free to pivot between the arms of the U-shaped bracket. Because the formed piece is a closed member, the oar cannot come out of the oarlock no matter how much the oar maybe moved or jostled by rough water, nor can the oar rotate on its own axis.
