US4082049A — Sailing cradle

Claim 1

Independent Claim 145 words

For use in combination with a boat having gunwales, a sailing cradle adapted to be supported by the boat, said sailing cradle comprising: (a) a first frame member adapted to mount over a first gunwale; (b) a second frame member adapted to mount over a second gunwale, substantially opposite the first gunwale; (c) first and second athwartship, connecting members, one being adapted to ride at the floor of the boat athwartship, both joining said first and second frame members; (d) mast receiving means in said first and second connecting members; and (e) at least one board member affixed to said first frame member outboard the gunwale and extending substantially below the water line to provide resistance to lateral motion of the boat, the cradle providing the structural rigidity to the combination necessary for sailing, with the boat merely furnishing the necessary buoyancy to the combination.

Claim 2

Dependent Claim 145 words

For use in combination with a boat having gunwales, a sailing cradle adapted to be supported by the boat, said sailing cradle comprising: (a) a first frame member adapted to mount over a first gunwale; (b) a second frame member adapted to mount over a second gunwale, substantially opposite the first gunwale; (c) first and second athwartship, connecting members, one being adapted to ride at the floor of the boat athwartship, both joining said first and second frame members; (d) mast receiving means in said first and second connecting members; and (e) at least one board member affixed to said first frame member outboard the gunwale and extending substantially below the water line to provide resistance to lateral motion of the boat, the cradle providing the structural rigidity to the combination necessary for sailing, with the boat merely furnishing the necessary buoyancy to the combination.

Claim 3

Dependent Claim 36 words

The combination of claim 1, above, including a second board member affixed to said second frame member outboard the gunwale and extending substantially below the water line to provide resistance to lateral motion of the boat.

Claim 4

Dependent Claim 66 words

The combination of claim 2, above, including third and fourth frame members adapted to mount over said first gunwales, respectively, said third and fourth members being affixed to said one and second board members, respectively, near the aft ends thereof; and longitudinal strut members for connecting said first and third connecting members and said second and fourth connecting members, respectively, at the floor of said boat.

Claim 5

Dependent Claim 119 words

For use in combination with an inflatable boat having buoyancy tubes and motor mounting beckets, a sailing cradle comprising: (a) first and second frame members adapted to partially enclose the buoyancy tubes forming the sides of the boat; said frame members being secured in place when the buoyancy tubes are inflated; (b) first and second forward cross members rigidly interconnecting said first and second frame members athwartship; (c) mast receiving means in said forward cross members; and (d) at least one board fastened to a frame member outboard said buoyancy tubes and adapted to extend below the water line to provide resistance to lateral movement of the boat, said cradle providing structural rigidity to the combination adequate for sailing.

Claim 6

Dependent Claim 119 words

For use in combination with an inflatable boat having buoyancy tubes and motor mounting beckets, a sailing cradle comprising: (a) first and second frame members adapted to partially enclose the buoyancy tubes forming the sides of the boat; said frame members being secured in place when the buoyancy tubes are inflated; (b) first and second forward cross members rigidly interconnecting said first and second frame members athwartship; (c) mast receiving means in said forward cross members; and (d) at least one board fastened to a frame member outboard said buoyancy tubes and adapted to extend below the water line to provide resistance to lateral movement of the boat, said cradle providing structural rigidity to the combination adequate for sailing.

Claim 7

Dependent Claim 27 words

The combination of claim 4 further comprising a mast member in said mast receiving means, and means for attaching halyards of a sail hoisted on said mast.

Claim 8

Dependent Claim 18 words

The combination of claim 4 further comprising a rudder assembly adapted to mount in the motor mounting beckets.

Claim 9

Dependent Claim 51 words

The combination of claim 4 further comprising a second board fastened to the opposite said frame member and outboard from said corresponding buoyancy tube and adapted to extend below the water line, said first and said second boards fastened to respective frame members positioned on opposite sides of the inflatable boat.

Claim 10

Dependent Claim 102 words

The combination of claim 4 further including third and fourth frame members adapted to partially enclose the buoyancy tubes forming the sides of the boat; (a) an after athwartships cross member, connecting said third and fourth frame members at the floor; (b) a second board fastened to the frame members opposite said one board, each of said boards being supported by two of said frame members; and (c) first and second struts connecting the forward and aft frame members on the same side of the boat at the floor into a substantially rectangular frame to impart additional structural rigidity to the cradle.

Claim 11

Dependent Claim 72 words

A kit of disassembled components adapted when assembled to form a sailing combination for an inflatable boat having buoyancy tubes, comprising: (a) a forward cradle member including port and starboard buoyance tube enclosing elements and upper and lower athwartships cross members having mast receiving means; (b) port and starboard strut members positioned to ride at the floor of the boat and adapted to connect said forward cradle member in a sailing cradle.

Claim 12

Dependent Claim 72 words

A kit of disassembled components adapted when assembled to form a sailing combination for an inflatable boat having buoyancy tubes, comprising: (a) a forward cradle member including port and starboard buoyance tube enclosing elements and upper and lower athwartships cross members having mast receiving means; (b) port and starboard strut members positioned to ride at the floor of the boat and adapted to connect said forward cradle member in a sailing cradle.

Claim 13

Dependent Claim 32 words

The kit of claim 9, further including port and starboard boards adapted to be connected to said cradle member outboard the buoyancy tubes, said boards when connected extending below the water line.

Claim 14

Dependent Claim 23 words

The kit of claim 9, further including a mast assembly comprised of telescoped sections adapted to be mounted in said mast receiving means.

Claim 15

Dependent Claim 22 words

The kit of claim 9, further including a rudder assembly including a blade and tiller portion, and means for mounting in beckets.

Claim 16

Dependent Claim 31 words

The kit of claim 9, further including sails and running gear adapted to be carried by the mast assembly and cradle members including stay jams adapted to be mounted on oarlocks.

Claim 17

Dependent Claim 32 words

The kit of claim 9, further including an aft athwartship member adapted to ride at the floor of the boat, connecting said port and starboard strut members into a rigid sailing cradle.
