Definitions

  • This invention relates to a trim and heeling board device for boats.
  • trim boards are used for stabilizing purposes, particularly in order to prevent alterations of the position or rolling of the boat in relation to its traverse horizontal axis through the center of gravity.
  • the trim boards used for this purpose generally comprise plates which in the normal position are approximately horizontal, and to which, dependent on the position of the boat, is imparted the necessary angular setting in relation to the direction of travel of the boat by manual operation by means of electrohydraulic actuating means, so that the intended stabilization of the position be achieved.
  • Such stabilizers will for natural reasons be fairly complicated and hence expensive, and in order to maintain stability they must also be subjected to constant survey and adjustment, which naturally also highly reduces the value of such arrangements.
  • FIG. 1 is a port side diagrammatic View of the rear portion of a boat provided with a trim and heeling board device of the invention
  • FIG. 3 is a diagrammatic port side view of a further embodiment of the invention.
  • FIG. 4 is a diagrammatic port side view of a further embodiment of the invention.
  • FIG. 6 is a rear elevation of the structure of FIG. 5.
  • the line 19 represents the plane of symmetry of the boat hull.
  • the right half of the transom 9 has a trim and heeling board, which is symmetrically positioned in respect of line 19 and identical to the trim and heeling board shown.
  • the trim and heeling board shown in FIGS. 1 and 2 is arranged perpendicularly to the plane of symmetry of the boat hull. However, particularly in boats having a V- shaped bottom, it may be convenient to let the two trim and heeling boards incline towards the plane of symmetry of the hull, since their stabilizing effect will be increased in this Way.
