Abstract

1,264,840. Planing craft. PENN YAN BOATS Inc. 17 April, 1969 [18 April, 1968; 18 Nov., 1968], No. 19709/69. Headings B7A, B7M and B7V. In a planing power boat the under surface of the hull 10 is recessed to define a tunnel 16 extending aft to the stern, the tunnel surface extending below the operating waterline for the hull. A propeller 17 is mounted in the after region of the tunnel so as to be substantially enclosed in the tunnel. A rudder blade 23 pivotally supported on stock 22 extends from the level of the bottom of the propeller to the top of the tunnel. In the embodiments shown spray plates such as 24 act as trim tabs which may also be hydraulically adjustable to assist longitudinal stability and a fixed vane 21 is mounted aft of the propeller to extend in a fore and aft direction. The spray plate may also be split to form a pair of trim tabs independently adjustable to correct uneven port and starboard loading of the boat. The rudder is balanced for ease of steering as 20% of blade 23 extends forward of stock 22.
