Definitions

  • a sailing rig for sailing boats comprises a main boom and a mast taken out of its socket. The foresail and the main sail are combined to form a single triangular sail and a sloping mast is provided at the leading edge of said combined said and connected thereto independently of the hull of the boat.
  • the substantially horizontal main boom is rotatably mounted to swing about a vertical axis in the socket for the mast in the hull and the forward end of the main boom terminates in a fork-shaped swing joint embracing the bottom end of the mast which extends through the fork-shaped swing joint downwards to below the sweep of the main boom, where its free end is connected by block and tackle and a spring to the fore part of the main boom.
  • This invention relates to a sailing rig for sailing boats comprising a main boom and a mast taken out of its socket.
  • Sports sailing boats usually have a main sail and a foresail and each of these sails is generally separately handled.
  • the substantially horizontal main boom being rotatably mounted to swing about a vertical axis in the socket for the mast in the hull, and the forward end having a forkshaped extremity embracing the bottom end of the sloping mast which extends through the fork downwards to below the sweep of the main boom, where its free end is connected by block and tackle and a spring to the fore part of the main boom.
  • FIG- URE is a side view of a boat provided with a sailing rig according to the invention.
  • the bottom edge of the sail is tied to the main boom 5.
  • the center portion of the main boom 5 is provided with a pivot pin 6 which is rotatable in the socket 7 of a conventional sailing boat mast.
  • the top 8 of the mast and the top of the sail 9 are in the produced vertical center line 10 of the socket 7.
  • the bottom end of the mast 3 is held in a fork-shaped swing joint 11 of the main boom 5. About one-tenth of the length of the mast extends through the swing joint 11 to below the sweep of the main boom.
  • This part 12 of the mast 3 is connected by block and tackle l3 and an adjustable spring 14 to the fore part of the main boom.
  • the adjustable spring 14 permits allowance to be made for the strength of the wind. In a sharp wind the spring 14 is relaxed, whereas a weak wind calls for the spring 14 to be tightened.
  • the sail can be evenly utilized.
  • the pull of the sheet is largely directly compensated and transmitted through the pivot pin 6 to the main boom socket 7. Only the forces due to the uncompensated sail area must be overcome when manipulating the sail, but the effort needed is relatively small because most of the area is compensated and can be easily provided by one crewman.
  • the swing joint 11 In order to limit the movements of the mast 3 the swing joint 11 is provided with stops 16 which may be adjustably fitted. For steadying the mast 3 a stay 17 may extend from the swing joint II to the top of the mast 8.
  • a sailing rig for sailing boats comprising a substantially horizontal main boom, a sail combined from a foresail and a main sail to form a single triangular sail and a sloping mast provided at the leading edge of said combined sail and connected thereto independently of the hull of the boat, the substantially horizontal main boom being rotatably mounted to swing about a vertical axis in a socket in the boat hull and the forward end of the main boom terminating in a fork-shaped swing joint embracing the bottom end of the mast which extends through the fork-shaped swing joint downwards to below the sweep of the main boom, where its free end is connected by block and tackle and a spring to the fore part of the main boom.
  • a sailing rig as defined in claim I wherein adjustable stops are provided on said fork-shaped swing joint of said main boom to limit the freedom of motion of said mast.
