Abstract
Arrangement for a boat (1) which has a boom projecting out from a mast (2) and designed to be connected to a sail, especially on a sailing boat (1). The invention enables the boom to be prevented effectively and reliably from swinging around the mast too rapidly on occasions when this is not desired, and thus reduces the risk of personally injury occasioned by the boom. The arrangement (5) is connected via one section (5A) to the boat (1) and is connected via a further section (5B) to the boom (3), the two said sections (5A and 5B respectively) being mutually connected in such a way that the arrangement (5) forcibly urges the boom (3) to swing towards a position substantially transverse to the boat (1).
Claims6
A boom control device for a sail boat having a mast, a mounting projecting from the mast, and a boom pivotally connected to said mounting and to be connected to a sail;
- said boom control device comprising:
- a unit having two sections, a first pivot directly connecting one section to said boat rearwardly of said mounting as viewed in the longitudinal direction of the boat to be spaced from said boom rearwardly of said boat, and a second pivot directly connecting the other section to said boom, said two sections forming a spring element such that the device urges the boom to swing out transversely across the boat from the longitudinal direction thereof and resists swinging back to the longitudinal direction, said device extending at a first angle in a vertical plane with respect to said boom and at a second angle in a horizontal plane when swung out across the boat, said spacing and angles being set so that urging force exerted on said boom by said spring element is maximum when the boom is oriented transversely of the longitudinal centerline of the boat and decreases to a minimum when the boom is oriented to extend along the longitudinal centerline of the boat.
