A stern drive for a boat is provided, which comprises an outer structure that is attachable to the stern of a boat, a housing supported in the outer structure, a gear set and reversing clutch inside the housing, said gear set including a pinion that is rotatable about a transverse axis and an output shaft that extends downwardly within a fairing. The housing is rotatable within the outer structure for steering purposes and the fairing and output shaft are rotatable about the transverse axis of s...
A method generates at least one route traversing a plurality of predetermined survey paths in a marine survey. The method includes generating a plurality of routes traversing a subset of the predetermined survey paths. The routes satisfy survey constraints such as run in and run out distances and minimum turn radius. Penalties are generated for the routes, including line change penalties, hazard penalties, streamer feather penalties, and penalties based on survey line priorities, total survey di...
A marine outdrive has a hydraulic vane motor with a spool shaped rotor eccentrically mounted in a fusiform shaped housing. The resulting increased vane area results in greater torque and speed.
A boat has a hull, a deck having a deck floor, and an engine disposed in the hull. A top of the engine is disposed vertically below the deck floor. The engine includes a crankcase, a crankshaft, a pair of cylinder banks connected to the crankcase at an angle relative to each other. A transom extends generally vertically upwardly from a rear portion of the hull. A stern drive unit is connected to the transom and is operatively connected to the engine through the transom. In another aspect, a mari...
The present application relates to a marine buoy featuring a novel bracing assembly disposed within a marine buoy and featuring a plurality of bracing members extending between and connecting to a first fastening member and a second fastening member.
Marine craft has a crushable frontal impact protection structure, comprising transverse bulkhead protecting passenger area; longitudinal crushable tubes; and transverse member. Webs and strengthen tubes, which may be made of extruded, heat treated aluminum; stainless steel; or plastic. Tubes in FIGS. 5 to 7 are splayed, to improve protection against angled impacts C. The forward ends of tubes are tapered, (FIG. 3) to initiate deformation. Tubes may be hexagonal, round, or oval in cross-section. ...
A marine vessel includes a hull and has at least one load carrying facility defined by at least one loading space with a given height, a given width and a given length, whereby the loading space is provided on a bulkhead deck, and a propulsion arrangement, which includes at least one steerable thruster unit connected by a shaft arrangement to a drive means. In order to provide better access to the bulkhead deck for loading and unloading the marine vessel, the steerable thruster unit is arranged ...
Various embodiments of an umbilical are provided. In one aspect, an umbilical is provided that includes a first tube, a second tube positioned in the first tube and a plurality of third tubes positioned in the first tube. Each of the plurality of third tubes has an inner polymer sleeve and an outer sleeve of carbon fibers in an epoxy matrix positioned around the polymer sleeve. The composite tubes yield a lighter umbilical that is easier to handle than a comparably sized conventional umbilical i...
A modular marine vessel has a variable hull and a plurality of boat forming modules including a bow section module, a load section module having a bow end and an aft end, and a bulkhead forming module is detachably connected to each bow and aft end of the load section module. The bulkhead forming module that is connected at the bow end of the load section module is detachably connected to the bow section module. Each boat forming and bulkhead forming module includes a topside section and a hull ...
A marine anchoring arrangement is described wherein a marine anchor (1, 23) is drivingly embedded vertically into a mooring bed (10) by an elongate follower (13), especially by its own weight and that of the follower. The follower (13) has a bottom clevis part (103) adapted to hold detachably the anchor (1) via the anchor shank (2) by means of a fulcrum pin (17) whereby the anchor (1) may swing relative to the bottom part (103). For initial penetration, the anchor (1) is held in a position of mi...
