Definitions

  • This invention relates to sailing vessels, and in particular to collapsible sailing vessels.
  • This invention is a twin-hulled sailing vessel.
  • the vessel is provided with a pair of elongate hulls, a pair of cross-members hold the hulls in alignment, and a trampoline extending between the cross-members.
  • the boat is further provided with a mast which is supportable by one of the cross-members and a sail.
  • the boat also includes a rudder assembly. To permit the vessel to be conveniently stored, the rudder assembly, the sail, the mast, the trampoline, and the cross-members are all sized and constructed to fit within one of the vessel's pair of hulls.
  • the vessel's hulls are each advantageously provided 5 with a retractable keel or daggerboard.
  • the hulls include a substantially open end, and the vessel is further provided with a pair of plugs which are insertable into the open ends to seal the open ends.
  • a pair of plugs which are insertable into the open ends to seal the open ends.
  • the rudder assembly includes a pair of rudder blades, each of which is mounted to one of the hulls by retractable pintle within the open end of the rudder assembly
  • each of the hulls is provided with a pair of raised yokes for receiving the cross-members, and the trampoline and the hulls are provided with mating Velcro fasteners to hold the trampoline taut. « n Description of the Drawings

  • Figure 8 is a cross section along lines 8-8 of the transom area of the vessel of Figure 1;
  • Figure 9 is a rear elevation of the transom area of the vessel of Figure 1;
  • Figure 10 is a detailed side elevation partially in cut-away of the rudder and transom area of the vessel of Figure 1;

  • Figure 12 is a perspective enlargement of the junction between hull halves of the catamaran of Figure 11;
  • Figure 13 shows a method of carrying the hulls of Figure 11
  • Figure 14 is a perspective view of an alternative embodiment of a vessel of the present invention utilizing a two-piece hull as illustrated in Figure 11.
  • a twin-hull vessel or catamaran 1 has a pair of hulls 2, each of which include a deck 4.
  • a pair of retractable keels or daggerboards 6 pass through a trunk 8 to extend below the hull to stabilize the vessel and to prevent side slip when the catamaran is under sail.
  • the hulls are connected by a pair of elongate cylindrical cross-members 10.
  • the mast 10 could also be of the telescoping variety.
  • the vessel includes a trampoline 12 having looped ends, which is suspended between the cross-members 10, so that the cross- members 10 support the bulk of the weight of the trampoline and any passengers resting thereon.
  • Mating Velcro fasteners on the trampoline 14 and the decks 6 help support the trampoline 12 and hold the trampoline tautly centered between the hulls 2. This means of attachment permits the trampoline 12 to be tightened to any desired tension and to be easily and quickly mounted and dismounted.
  • a two-piece mast 20 is supported within a step 22 in the forward cross-member 10.
  • a forestay 24 and a pair of shrouds 26 hold the mast 20 in place.
  • the vessel is steered by a rudder assembly 30 which will be described in greater detail hereinafter.
  • the vessel 1 is shown with a main sail 40 and a jib 42.
  • the ib 42 is trimmed by sheets 46 and 44, respectively.
  • all the components of the vessel, including its mast 20 and sails, 40 and 42 can be stowed within the hulls 2 on either side of the centerboard trunk 8.
  • the cross-members 10 are stored with the trampoline wound between them.
  • Each hull includes a pair of raised yokes 50 for receiving and retaining the cross-members 10.
  • the cross-member 10 is received within the yoke 50 and is held there by a single bolt 52 having a handle portion 54, a shaft portion 56, a nd a threaded portion 58.
  • the threaded portion 58 passes through a C-shaped clip 60 and is threaded into the yoke 50.
  • the clip 60 secures the bolt 52 to the cross-member 10 and prevents the bolt 52 from being lost when the vessel is disassembled.
  • the yoke is advantageously provided with a metal plate 61 which reinforces the connection between the bolt 52 and the yoke 50 and distributes the stress of the connection over a larger surface area.
  • the yokes 50 overcome any torque about the axis of the bolts 52, thereby permitting a single bolt to be used to attach each cross-member 10 to each hull 2.
  • the flat upper surfaces 51 of the yokes 50 permit the two hulls 2 of the catamaran 1 to be stacked deck-to-deck on top of one another for convenient storage. While stored in this manner, the mating upper surfaces of the yokes will be the only portion of the two hulls touching one another. This means that the yokes 50 of the lower hull 2 will support the entire weight of the upper hull.
  • a short length of tubing equal in diameter 5 to the cross-members 10 may be positioned between each pair of mating yokes to prevent the hulls from sliding relative one another during storage.
  • the tubular body 70 of the hull 2 is provided with a seat 72 mounted to the inner wall of 0 the tubular body to align and limit the axial movement of a plug 74 within the hull.
  • the plug is comprised of a pair of compression plates 80 mounted on a bolt 82. Between the plates 80 is a layer of foam rubber 84.
  • a handle 86 is mounted on one end of the bolt 82 and a nut
  • the rudder assembly at the rear of each hull includes a rudder blade 90 and a tiller 92, both of which are mounted to a rudder head 94.
  • the rudder blade is preferably rotatably mounted to the rudder 0 head by a pivot pin 96.
  • the tiller 92 is rotatably mounted to the rudder assembly 30 by a pivot pin 100.
  • the pivot pin 100 permits the tiller 92 to be rotated counter ⁇ clockwise (as shown in Figure 10) until the tiller 92 is vertical and is prevented from further rotation by the 5 cylindrical upper edge 93 of the rudder head 94.
  • the end of the tiller 92 which rotates within the rudder head 94 is cupped by a partial cylindrical wall within the rudder head 94 when the tiller 92 is vertical.
  • This mechanism permits the blade 90 and the tiller 92 to be easily stored within the hull 2.
  • the blade 90 can also be rotated backward from the hull about the pivot pin 96 to avoid collision damage when the boat is in shallow water or is being beached.
  • a handle 102 is also provided to permit the blade 90 to be manually raised.
  • a Velcro strip 104 releasably holds the blade to the head 94.
  • the rudder assembly 30 is rotatably mounted to each hull by two pintles, 110 and 112, which are mounted on the head 94, and are fitted rotatably into holes 120 and 122 5 in the hull.
  • the lower pintle 12 is fixed to the head 94 and fits into the hole 120 which extends through the seat 72 and the hull 2.
  • the upper pintle 110 mounts into a hole 122 in the seat 72 and the deck 4 of the hull 2. To permit 0 the quick and easy installation of the rudder, the pintle 110 moves up and down relative the head 194 in a channel 130.
  • a pintle pull down shaft 132 permits the retraction of the pintle 110 downward out of the hole 122 and into the channel 130. Whenever the pintle pull-down shaft is released, a compression spring 134 within the channel 130 biases the pintle 110 outward.
  • the vessel has a forward container 140 and a rear container 142 held together by a latch system 144.
  • a sleeve 146 causes the two containers 140 and 142 to slide together in a tight fit.
  • the latch system 144 has a hook 150 on one container, a claw 152 on the other container, said claw 152 being mounted to a compression lever 154 that pivots at 158 about a base 160 mounted upon the hull 2.
  • the claw 152 is locked over the hook 150 which is then pulled tight by the compression lever 154. This compresses an 0-ring 162 into an O-ring seat 164 thereby creating a water-tight seal.
  • the two containers 140 and 142 can be seen to be easily carryable by one person using handles 170.
  • these handles are located at the center of weight of each container.
  • all exterior equipment of the vessel including the mast, rudder, keel, cross-members 10, sails 40 and 42, and trampoline 12 can easily be carried in the four containers 140 and 142 formed from the two hulls of the catamaran.
  • Figure 14 shows this embodiment in its assembled form.
