Der um den Bolzen d drehbar gemachte Mastbaum m führt sich an seinem unteren Ende zwischen den beiden gebogenen Eisen/. Unterhalb des Drehpunktes d ist an dem Mastbaum m ein Ring r angebracht, an dessen beiden Vorsprüngen ν seitliche Kolbenstangen s angreifen, deren Kolben k gegen Spiralfedern ρ drücken. Die in den Führungshülsen h befindlichen Spiralfedern ρ können von der hinteren Seite durch Eindrehen der Schraube i mittelst des Handrades g straffer gespannt werden. Während die Führungshülsen h an dem Sitzbrett b des Bootes ihre Befestigung finden, ist das Lager für den Drehpunkt d durch die Arme a mit den das untere Ende des Mastbaumes führenden Eisen f verbunden, welch letztere mit passenden Stücken u auf dem Boden des Bootes befestigt sind. Soll der Mastbaum festgestellt werden, so geschieht dies durch den Bolzen o, welcher durch die Führungseisen/ und das untere Ende des Mastbaumes gesteckt wird.The mast boom m , made rotatable about the bolt d , runs at its lower end between the two curved irons /. Below the pivot point d , a ring r is attached to the mast boom m , the two projections ν of which engage lateral piston rods s , the pistons k of which press against spiral springs ρ. The spiral springs ρ in the guide sleeves h can be tightened from the rear side by screwing in the screw i using the handwheel g. While the guide sleeves h are attached to the seat board b of the boat, the bearing for the pivot point d is connected by the arms a to the iron f leading to the lower end of the mast, the latter being fastened to the bottom of the boat with suitable pieces u . If the mast boom is to be fixed, this is done by the bolt o, which is inserted through the guide iron / and the lower end of the mast boom.
Ein auf diese Weise angeordneter Mastbaum kann sich senkrecht zur Längsrichtung des Bootes bewegen, und wird diese Bewegung durch mehr oder weniger Straffspannen der Spiralfedern mehr oder weniger Kraft erfordern. Bei plötzlichen und heftigen Windstöfsen wird ein den Stöfsen federnd nachgebender Mastbaum einem Umschlagen des Bootes in manchen Fällen vorbeugen.A mast boom arranged in this way can extend perpendicular to the longitudinal direction of the The boat moves, and this movement is made by more or less tensioning the Coil springs require more or less force. With sudden and violent gusts of wind a mast boom which resiliently yields to the stoppers becomes a turning over of the Prevent boats in some cases.
