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.
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.

Referring generally to
In one aspect of the present invention, the sailing vessel 100 may include a set of parallel hulls. For example, the sailing vessel 100 may include, but is not limited to, left and right parallel hulls. In another aspect, the sailing vessel 100 may include a set of cross-member spars releasably connecting the parallel hulls. For example, the sailing vessel 100 may include, but is not limited to, fore and aft arced spars attached substantially perpendicularly to the left and right parallel hulls of the sailing vessel 100. In another aspect, the sailing vessel 100 may include a longitudinal body centrally located between the parallel hulls and releasably connected to the set of cross-member spars. In another aspect, the sailing vessel 100 may include a crew seat releasably connected to the central longitudinal body at a position forward of the mast of the vessel. For example, the sailing vessel 100 may include, but is not limited to, a central longitudinal body assembly attached perpendicularly to the fore and aft spars and located centrally between the left and right parallel hulls to which are attached a collapsible seat situated in front of the mast location. In another aspect, the sailing vessel 100 may include a kick-up rudder assembly and a foot pedal steering system both releasably connected to the longitudinal body. For example, the sailing vessel 100 may include, but is not limited to, a single kick-up rudder assembly situated at the stern of the central longitudinal body and connected to a foot pedal steering mechanism also attached to the central longitudinal body. In another aspect, the sailing vessel 100 may include a rudder releasably connected to the kick-up rudder assembly. In another aspect, the sailing vessel 100 may include a main sail on the mast, and a jib. For example, the sailing vessel 100 may include, but is not limited to, a mast assembly with side-stays and a forestay, and a sail assembly consisting of a fully battened, boom-less mainsail, and a jib. 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 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.
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 one embodiment, the left and right hulls 101a, 101b are constructed of exterior fiberglass. In another embodiment, the left and right hulls 101a, 101b are constructed of carbon fiber. In another embodiment, the left and right hulls 101a, 101b are constructed with internal foam. In another embodiment, the left and right hulls 101a, 101b are shaped to provide a desired stern planing configuration 116 and wave splitting-planing bow configuration 117. 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
Referring now to
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.
The sailing vessel 100 is reversibly assembled using various assembly procedures. In a first step, the removable fixed pins 127 (or arced fore and aft spar fixed pins 128) into the hull pin receivers 129, as illustrated in
The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “connected”, or “coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “couplable”, to each other to achieve the desired functionality. Specific examples of couplable include but are not limited to physically mateable and/or physically interacting components.
