Twin rudder construction

For anyone who’s interested, I’ve cobbled together some scruffy sketches and instructions for making twin rudders stern hung as a modification for Drascombe Luggers and Longboat variants, the drawings are NOT TO SCALE and no measurements are given,(the transom is at 37 degrees) however, it should not be too difficult for anyone to determine the size and position of the rudders by making hardboard patterns before proceeding with the build. Do make certain to allow for unobstructed movement and sufficient clearance for stern to beaching without grounding the blades.

To build the rudders, begin by making hardboard or similar material patterns, when satisfied with them, use 9 mm marine ply for economy of materials as well as keeping the weight down, (unless you already have some other suitable material to hand).

Best regards,
