Abstract: A system for mooring a floating storage vessel (10) in the open sea for remaining on station at all times without any disconnection of the vessel (10) from the mooring system. The mooring system includes a plurality of anchor legs (26) connected to a turret (20) in the well (18) of the vessel (10) with at least one submerged support buoy (28) for each anchor leg (26). The submerged support buoy (28), by supporting a substantial portion of the weight of the associated anchor leg (26), reduces the vertical loads on the turret bearings (46, 48) and permits the turret (20) to be easily rotated from the torque exerted by the anchor legs (26) without any separate turret drive means. The system includes in FIG. 5 an embodiment in which a plurality of support buoys (28A) are provided for each anchor leg (26A). The system includes in FIG. 6 an embodiment in which the floating storage vessel (10B) is permanently moored to a mooring buoy (25B) secured by a plurality by anchor legs (26B) to the sea bed (16B).
Abstract: A bearing support structure is disclosed for a turret (10A) mounted for rotation within a well (50A) of a moored vessel. The bearing support structure has a turret bearing assembly (900A) which may tilt about a tilting axis (783A, FIG. 3) relative to a lower bearing support structure (764A) mounted on the vessel. The turret bearing assembly (760A) has a retainer ring (794A) below a peripheral slot (782A) in a turret ring (102A); a segmented key (596A) fits in slot (782A). The retainer ring (794A) is supported on an annular abutment (780A) on turret ring (102A). A filler material (781A) is provided in an annular space or clearance between turret ring (102A) and retainer ring (794A) to tighten the joint therebetween. A construction method is also disclosed for first placing a mooring turret in the well of the vessel and later installing a bearing assembly between the vessel and the turret by lowering it over the top of the turret.

Abstract: In a power tilt device, an opening/closing valve is arranged in a free piston, and an operating member is arranged within a piston rod of a piston and piston rod assembly contained within a closed cylinder. The operating member contacts a supply of hydraulic fluid from an opposite piston side space of a free piston to a first chamber above the piston by opening the opening/closing valve when coming into contact with an end wall of the cylinder during an upward tilting phase of the boat motor. Upon contact, the piston rod is extended outside of the cylinder causing a discharge of hydraulic fluid from the first chamber to an external reservoir, during which time the piston side space and the opposite side space of the free piston are fluidly interconnected.
Abstract: A towable watercraft is provided with a tow bar which extends over a front portion of a hull of the watercraft, and downwardly along the outside of the hull front portion to an elevation where a tow line can be secured to an end portion of the tow bar.

The steering system includes a steering column turned by a steering wheel or bar, a steering drive shaft secured to the tow bar and pivotally supported relative to the hull, and a gear mechanism or a pulley mechanism linking the steering column and the steering drive shaft and providing a substantial mechanical advantage. A housing is provided for the steering system to contain the drive shaft and the linking mechanism.

Abstract: A personal watercraft includes a component arrangement which reduces heat exposure to many critical, heat-sensitive components of the watercraft. The personal watercraft includes a calalyzer within an exhaust system to treat engine exhaust before discharge. The catalyzer operates at a high temperature.

The elongate member includes an arcuate form having a surface that substantially conforms a portion of the surface of the pontoon. The elongate member also includes a channel which receives a lip extending radially from the pontoon. The interference between the channel and the lip prevent the pontoon from being radially removed from the elongate member. The surface of the arcuate form may include ridges.
Abstract: A stabilized float drum is shown having interlocking side and end walls and an upper compartment filled with a flotation medium such as closed cell foam and a lower member with a selected number and size of holes in the surfaces thereof to admit water which then acts as a stabilizing force when the float is subjected to upsetting wave action or eccentric loads. The degree of stabilization or damping is controlled by the relative size of the lower member and the size, placement and number of holes.Various baffle members are shown which provide varying degrees of resistance to unwanted displacement of floating docks.
Abstract: A weed grate for a watercraft having a jet propulsion unit. The weed grate includes a plurality of cantilever tines each joined to a pivot rod. The cantilever tines extend across the inlet opening for the jet drive to prevent debris from entering through the water inlet opening. A spring member is mounted between the cantilever tines and a mounting frame such that the spring member provides an outward rotational bias force against the rotatable cantilever tines. During operation of the watercraft, if a mass of weeds becomes clogged in the cantilever tines, the upward and inward suction force of the jet drives causes the cantilever tines to rotate upward against the rotational bias force and allow the weeds to be ingested by the jet drive.
