Abstract
825,794. Drop-keels. MILLER, F. L., OWEN, F. E., and COOLMOTA Ltd. July 18, 1958 [July 30, 1957], No. 24120/57. Class 114. A replaceable dropkeel and housing assembly comprises a channelled watertight support housing 40 carrying a pivotable dropkeel 20 including a centre board 21 and quadrant shaped plates 25 partly surrounding the centre board to strengthen the dropkeel and enable the centre board to break below the plates 25 if the craft is driven aground with the centre board lowered. The dropkeel is raised and lowered by means of handle or actuator 101 secured on the end of a pivot 30 supported in a packing gland assembly on the housing 40 and having a rectangular portion which fits in a rectangular aperture in the drop keel.
