Watercraft covers are often large and awkward to manually handle, making them difficult to install on a watercraft and to store on-board the watercraft. The covers are also often dirty, and unpleasant to handle. The present invention provides a watercraft covering apparatus with pivot arms moved by at least one actuation member to self-install a fitted three-dimensional watercraft cover on a watercraft using a torsion spring in conjunction with a roller to keep the cover tight on the roller when pivot arms supporting the roller are pivoted rearward by the actuation member and self-roll the cover off the roller when the pivot arms supporting the roller are pivoted forward by the actuation member. A slip clutch prevents the torsion spring from being over tightened. The forward position of the roller is adjusted by adjusting the length of the actuation member, typically a retractable member such as a hydraulic cylinder. The rearward position of the roller is adjusted by limiting the retracted position of the actuation member.

    Dispositif de levage de bateau doté de bras actionnés de manière hydraulique ou mécanique qui auto-installe une housse de protection de bateau tridimensionnelle ajustée sur un bateau à moteur. La logique de commande du système permet une opération de recouvrement uniquement lorsque le dispositif de levage est soulevé. Un rouleau tendu par un ressort maintient la housse tendue et auto-enroule la housse sur le rouleau lorsque les bras actionnés pivotent vers l'avant. Le rouleau est caché derrière le bateau dans position 'en recouvrement'. Un embrayage à glissement empêche le ressort de torsion d'être trop serré. La position avant du rouleau est ajustée par l'ajustement de la longueur du cylindre hydraulique. La position arrière du rouleau est ajustée en limitant la position rétractée du cylindre hydraulique. Un mode de réalisation non-hydraulique actionne la housse lorsque le dispositif de levage est actionné.
