A sail (20) for a sailing vessel (500) includes a leading spar (22), a coplanar trailing spar (24), and a movable spar (28) disposed between the two.
The present disclosure provides an improved design for a multi - sectional truss spar hull platform having a truss (34) and a spar hull.
A fish pen (100) includes an elongate spar buoy (110) and a reserve buoyancy buoy (120) disposed over a top end of the spar buoy.
The integral skirt tank will be flooded after the spar hull is up - ended.
In some other embodiments, the spar platform is a single long tube.
Various mechanisms could convert the relative motion between the floats and the spar buoy to a rotational motion of the shaft.
A person or article retrieving device for boats comprises a main boom (12) which can be swung out over the edge of the boat.
The device comprises a polar mechanical axis consisting of a free-to-rotate spar (11) to which the mast (15), centreboard, winches, rope stoppers and any other rings for fastening the rigging are solidly connected.
A stringer (18) extends between the head ends of the masts, and a series of sail assemblies (20) are mounted on the stringer, each sail assembly comprising a spar (26), booms (28), and a sail (30).
The device includes the extension arm (2) rotationally connected with the main hull and resting by means of a transverse spar (4) on auxiliary hulls (5 and 5') as well as on the driving surface (1) placed in it.
The dihedral angle between the wings can be varied by a system of adjustable stays between the masts and the upper and lower ends of the spar.
This invention relates to a floating construction (11) such as for instance a SPAR buoy, which is connected to the seabed (32) by means of tethers and/or risers (15, 16).
A small diameter luff spar (6) having a high strength to weight ratio, comprising of a luff wire (5) encapsulated within a fibre based material tube (1).
The Boxes may be positioned on moving or fixed platforms, such as the HVUs themselves, navy ships, USVs or spar-type buoys.
A wave energy converter (WEC) having an asymmetrically shaped float and a spar which move relative to each other in response to the waves.
A component according to an exemplary aspect of the present disclosure includes, among other things, a shell defining an interior, a spar extending into the interior and a first flange attached to the spar.
The Finned-Spar-Buoy (FSB) design can be considered an exoskeleton, in that vertical fins are externally mounted on a vertical cylindrical float.
