Portable Wind-Powered Sailing Vessel

Description

TECHNICAL FIELD

The present invention relates to the field of sail vessels, such as sailboats, having multiple hulls, such as catamarans. In particular, the present invention relates to sailing vessel design configurations that provide vessel transportability, vessel assembly, user visibility and operational simplicity.

BACKGROUND

Multiple variations of small sailing craft, car top-able or trailer-able, have been developed in an attempt simplify the overall sailing experience and introduce new consumers of all ages to the sport and leisure activity. Most simplification attempts have involved assembly processes, transportability features related to bulk and weight, and variations of kick-up rudders. Other variations attempt to enhance stability through the deployment of outriggers, hydrofoils, or specialized mast and sail rigging. Variations of mono-hull, catamaran and tri-hull designs are well known in the present marketplace.

Mono-hull car-top sailboat hulls are of the planing hull variety but are bulky, difficult to car-top by one person, and highly unstable when sailed for speed requiring frequent shifting of crew weight to provide stability. Multi-hull car-top catamarans employ wave piercing displacement hulls, having a tendency to pitch-pole as a result, and require frequent shifting of crew weight to provide lateral and longitudinal stability. Some catamarans incorporate a hull design that is capable of planing, but in a severe laterally canted position referred to as “flying a hull” where one hull is raised completely out of the water and extreme shifts in crew weight and position are required to remain upright. Tri-hull designs generally provide more stability through the deployment of outriggers to provide a wide beam but must be trailered, and require significant assembly time. In all varieties of car-top sailboats the crew is seated toward the stern of the boat, and behind the mast, which restricts forward visibility. Frequently cited negative characteristics include a wet sailing experience, instability and easy to capsize, and pitch polling (poor longitudinal stability). Small sailboats in the present marketplace, and published designs, fail to address in one product, many of the cited negative characteristics and do not incorporate all of the positive characteristics. The present invention is directed toward improvements in multi-hull sail boats, particularly to those of the catamaran class.

The remainder of the present disclosure will describe various aspects of the sailing vessel 100 of the present invention. While the following and foregoing description of the sailing vessel 100 illustrates on one or more configurations of the sailing vessel 100, it is recognized herein that the sailing vessel 100 is not limited to the illustrated embodiments of the present disclosure. Applicant notes that for the purposes of the present disclosure the terms “sailing vessel” and “sail boat” are used interchangeably.

FIG. 1 illustrates a schematic view of the assembled sailing vessel 100, in accordance with one embodiment of the present invention. In one embodiment, the sailboat 100 includes a parallel left hull 101a and right hull 101b. It is noted herein that the use of the terms “left” and “right” is with respect to a user in the seated position of seat 108. In another embodiment, the sailboat 100 includes an arced fore spar 103 and arced aft spar 104 perpendicular to, and releasably and opposingly connected to, the parallel hulls 101a and 101b. In another embodiment, the sailboat 100 includes a central longitudinal body 105 arranged perpendicular to and releasably connected to the spars 103 and 104. In another embodiment, the sailboat 100 includes a mast base 106. In another embodiment, the sailboat includes a kick-up rudder assembly 107 equipped with a control line or rod 115 releasably connected to the foot pedal steering assembly 109. In another embodiment, the sail boat 100 includes a collapsible crew seat 108. In an additional aspect, the parallel hulls 101a and 101b, the spars 103 and 104, the mast base 106, the kick-up rudder assembly 107 and the collapsible crew seat 108 are each releasably connectable to the central longitudinal body 105. In another embodiment, the mast 110 is releasably connected to each of the mast base 106, the arced aft spar 104 with side stays 111, and to the central longitudinal body 105 with a forestay 112. In another embodiment, the rudder 113 is releasably connected to the kick-up rudder assembly 107 with a retracting control line 114 terminating at a location on the central longitudinal body 105 at or near the crew seat 108. In a further embodiment, the sail boat assembly 100 includes a fully battened, boom-less, mainsail 137 and a self-furling jib 138.

It is noted herein that the assembly of the sail boat 100 of the present invention does not require tools, bolts, knobs, or straps as connecting devices. In this regard, the fore and aft spars 103 and 104 may be joined to the left and right hulls 101a, 101b utilizing opposing pin-receiver assemblies, which are further held in place by attaching the central body 105 to the fore and aft spars 103, 104 utilizing a pin-receiver assembly, which is further held in place by opposing forces generated by the mast forestay and side-stay connections. In an alternative embodiment, it is recognized herein that the sail boat 100 of the present invention may implement other coupling technologies such as, but not limited to, cam latches, straps, removable pins, pin and Velcro strap combinations, and other attachment means suitable for attaching the spars 103, 104 to the parallel hulls 101a, 101b.

It is noted herein that the various components and assemblies of the sailboat 100 produce a sailboat beam wide enough to provide a high level of lateral stability and obviate the need for crew shifting.

In another embodiment, the positioning of the crew, the arced spar attachments to the left and right hulls, and the central longitudinal body are configured to provide a center of gravity located behind (e.g., slightly behind) the center of hull buoyancy. It is noted herein that by positioning the center of gravity behind the center of hull buoyancy a high level of longitudinal stability may be achieved. In a further embodiment, the arced spars, the hull connections and central longitudinal body are further configured to provide some structural “twist,” which serves to minimize, or at least reduce, the pitch-polling tendencies of rigidly designed catamarans.

It is further noted herein that the collapsible crew seat 108 attached to the central longitudinal body 105 ahead of the mast 110 provides unrestricted forward visibility. Applicant notes that the forward positioned collapsible seat 108 is a novel feature providing significant visibility benefits over the position of the crew behind the mast 110 and sails 137 as found in the prior art. In a further embodiment, the positioning of the crew seat 108 acts to raise the crew vertically from underlying water by a larger degree than crews positioned behind the mast 110 and sails 137, providing a substantially dry sailing experience.

In another embodiment, each of the left and right hulls 101a, 101b are separated into two longitudinal halves, which are affixed to a central stringer 118 formed of a selected material (e.g., wood, PVC, carbon fiber, and the like). In another embodiment, each of the left and right hulls 101a, 101b includes a stern planing surface 116 extending from the center of hull buoyancy 119 to a wide stern 120, incorporating a slightly raised transom 121 and culminating in a low drag stern profile 122. In another embodiment, a combination wave splitting-planing bow hull shape extends from in front of the center of hull buoyancy 119 to the bow 123, as shown in FIG. 2A.

Referring now to FIGS. 2B-2D, a series of bow cross-sectional views suitable for implementation in each of the left and right hulls 101a, 101b are depicted, in accordance with embodiments of the present invention. In one embodiment, as shown in FIG. 2B, the bow of the left or right hull 101a, 101b may have a rounded convex “v” shape 124, which acts to provide the desired wave-splitting action. In another embodiment, as shown in FIG. 2C, the bow of the left or right hull 101a, 101b may have a “v” shape 125, which acts to provide the desired wave-splitting action. In another embodiment, as shown in FIG. 2C, the bow of the left or right hull 101a, 101b may have a rounded concave “v” shape 126, which acts to produce the desired wave-splitting action.

In a further embodiment, the aforementioned bow shapes of the bow of the left or right hull 101a, 101b may be further improved with the addition of a bow planing shape and additional displacement volume 150 to avoid pitch-polling. In a further embodiment, the bow of the left or right hull 101a, 101b may have a low vertical profile to enhance transportability. It is recognized herein that alternative construction methods may include a rotational molded plastic hulls or the attachment of alternative skin surfacing materials, such as molded plastic skins, or other materials.

In one embodiment, the central body 105 includes a longitudinal shaft 130 formed from a selected lightweight material, such as aluminum or carbon fiber, covered with foam 131 and a skin layer 132 (e.g., a fiberglass skin or carbon fiber skin) to produce the desired cross-sectional shape. It is recognized herein that the desired structure and shape of the central body 105 may be alternatively produced with molded fiberglass or carbon fiber. In other embodiments, various recesses, payload compartments, or connecting devices may be built into or attached to the longitudinal body 105 in order to carry payloads.

FIG. 6 illustrates a schematic view of the pin receivers 134 of the central longitudinal body 105 releasably fixed over the fixed pins 140 of the arced fore and aft spars 103, 104. In this regard, pin receiver 134/fixed pin 140 configuration acts to secure the opposing fore and aft arced spars 103, 104 by attaching the spars 103, 104 to the central longitudinal body 105. In a further embodiment, the central body 105 may include a pair of grooves (as shown in FIG. 6) conformed to the profile of the fore and aft spars 103, 104 and suitable for receiving the spars 103, 104. In addition, each the grooves of the central body 105 may include pinholes suitable for receiving the shaft of the pins (e.g., L-shaped pins) disposed on the spars 103, 104. For example, L-shaped pins disposed on the spars 103, 104 may be slid into the pin receivers 134, thereby locking the fore and after spars 103, 104 into the corresponding grooves of the central longitudinal body 105.

FIG. 7 illustrates a schematic view of the kick-up rudder assembly 107 and rudder 113 in the down position, in accordance with one embodiment of the present invention.
