Abstract: A portable marine outhaul has a closed loop of line strung between pulleys attached to a pair of anchors, e.g. sea and land anchors, and used to keep a boat moored off a temporary shore. The outhaul uses a reel rotatably mounted inside a housing. One half or run of the line, preferably fed through one hole in the housing, is wrapped on one half of a spool of the reel. The other half or run is fed through a second hole in the housing, spaced from said first hole a sufficient distance to control tangling. This other run is wound in the same direction onto the other half spool of the reel. In a manually-operated form, a crank turns an axle attached to the center of the spool. Initially attached to either anchor, the outhaul unwinds until reaching the other anchor where it is attached. The two lines of the outhaul are then cleated or otherwise secured, preferably to the side of the container. This completes the outhaul loop. The boat is then attached to the loop and can be pulled off shore and on shore at will.

Abstract: Floating structures are provided. The floating structures are suitable for use as floating runways for aircraft, floating roadways, and supports for other facilities.

The basin provides damping or isolation of forces due to currents in the body of water, or prevailing winds, to reduce undesired or excessive motion of the deck. The deck supports are preferably capable of limited lateral movement relative to the pontoons, thereby permitting some movement of the pontoons independently and reducing stresses on the structure.

Abstract: Tunable sponsons for personal watercraft and personal watercraft having the tunable sponsons. The present invention provides personal watercraft having sponsons with an adjustable height relative to the water surface and the hull.

The effective height of the sponson outwardly extending portion above the water can be reduced or lowered by adding a thickness of slab of material along the length under the sponson outwardly extending portion. One tunable sponson includes apertures mounted along the sponson underside for securing additional material. The effective height of the sponson horizontally extending portion above the water can be increased by removing a removable sponson extension previously secured to the sponson.

Abstract: A mooring system that uses combination traction winch/windlass units is improved by adding an additional fairlead at each combination unit location and by increasing the strength of existing combination units, their foundations and the foundations of associated equipment such as fairleads and turning sheaves. By these relatively simple upgrades, the mooring capabilities of the system can be economically augmented in those situations where additional lines are desired, such as in areas subject to tropical revolving storms. Normal mooring, when there is no threat of hurricanes, has the anchor and chain attached to the floating structure by wire deployed from the traction winch. When storm season threatens, additional anchors attached to chain run over the windlass can be added, allowing the number of lines to be doubled. The additional anchors can be installed if the floating structure is conventionally moored or if it is attached to pre-set moorings.
