Abstract
1,178,421. Trimming and stabilizing marine craft. B. E. ILON. 25 April, 1967 [25 April, 1966], No. 18948/67. Heading B7M. Apparatus, or structure, for stabilizing a boat comprises a flat plate 1 that is coupled to a bracket 10 ... 16 on the transom 9 by pairs of pivotally connected links 5, 6, a tension spring 17 being attached to said bracket and a bar 18 connecting the links 6 to each other. The plate is biased towards a position wherein it abuts the transom and has a horizontal attitude relative to the hull 3; and when the stern of the boat is depressed by, e.g. a load applied to the hull abaft its centre, the trim is corrected while the craft is under way owing to the angle of attack of the plate 1 becoming positive (instead of zero) and the plate being consequently displaced to a position shown in phantom lines (Fig. 1) wherein its angle of attack is greater so that the lift effected by the plate is increased accordingly. Identical apparatus is provided on either side of the plane-of-symmetry 19 of the hull so that rolling is minimized; and, to this end, the two plates 1 may be inclined towards said plane so as to increase the stabilizing torque. In a second embodiment, Fig. 3 (not shown), the plate 1 is supported by a pair of brackets (22) that are attached to the transom 9 and provided with slots (21) containing pins (20A), which are fixed to the plate, the said slots being such that the plate can be displaced into a position substantially similar to that shown in phantom lines in Fig. 1 against the action of a spring (20B). In a third embodiment, Fig. 4 (not shown), the plate (26) is supported by a pair of downwardly-extending arms (24) that are pivotally attached at their lowermost ends to a bracket (23) fixed to the bottom of the hull, the plate being biased as before by a spring (27). In a fourth embodiment, Figs. 5 and 6 (not shown), the plate (33) is supported in a manner somewhat similar to that shown in Figs. 1 and 2, the spring 17 being dispensed with.
