- 1. In an arrangement for anchoring watercraft floating on a body of water, a combination comprising anchor means disposable at the bottom of the body of water; variable buoyancy buoy means including a generally hollow float body provided with a recess; means for connecting said buoy means to said anchoring means; means for varying the buoyancy of said buoy means; means for actuating said varying means so as to submerge and surface said buoy means by varying the buoyancy thereof; mooring means including a mounting portion mounted in said recess of said float body for pivoting with respect to the latter about a substantially horizontal axis and a rapid-release slip hook on said mounting portion and operative for anchoring the watercraft thereto when said buoy means is surfaced and for releasing the watercraft during the submerging of said buoy means; an auxiliary float on said body, flexible conduit means connecting the auxiliary float with said body; means for normally holding said auxiliary float to said body; and pressure responsive means for automatically releasing the auxiliary float when said body has sunk to a predetermined depth.
- 2. A combination as defined in claim 1, wherein said flexible conduit means comprises air hose means, connected with the hollow interior of said body.
- 3. A combination as defined in claim 1, also including radio means for receiving signals and for controlling said varying means.
- 4. A combination as defined in claim 3, wherein said auxiliary float carriers at least part of the radio means.
- 5. A combination as defined in claim 1, wherein said varying means includes flood valve means for flooding regions of said hollow float body and actuated by said actuating means so as to admit a sufficient quantity of water into said regions for submerging said float body.
- 6. A combination as defined in claim 5, wherein said flood valve means is movable between an open and a closed position, and wherein said flexible conduit means comprises control conduit means for controlling the position of said flood valve means.
- 7. A combination as defined in claim 1, wherein said varying means further comprises means for expelling water from regions of said hollow float body and actuated by said actuating means so as to expel a sufficient quantity of water from said regions for surfacing said float body.
