* b) Maximum distance from inside transom (excluding fashion piece) to a line joining centre of pin holes is not to be more than 8 11½".
 
 

(Addition) 23. * c) Minimum angle between leading edge of rudder when fully down and extension of keel at point of intersection to be not less than l05 degrees.
 
 

(Addition) 24. * c) Minimum angle between leading edge of centreboard when fully down and tangent to keel at point of intersection to be not less than 100 degrees.

(Change) 29. Buoyancy 
The two transverse bulkheads must be watertight, but may be fitted with hatch openings as specified in rules 9(d), 9(e), 13(b), 13(c), and water-tight hatch covers. Two drain holes, of maximum diameter 1" are permitted in bulkheads and transom, but must be effectively stoppered while the boat is in the water. It is not practical fully to test the buoyancy compartments by total immersion owing to their large volume. Measurers are to check all watertight joints and satisfy themselves that they are efficient and that the hatches are adequately watertight. The owner is advised to test the buoyancy annually by floating the boat in a waterlogged condition, with the water overflowing the top of the centreboard case. After 20 minutes in this condition the boat should be bailed out and the tanks inspected for leakage.

Running of main sail sheet and pulley blocks from centre of boom to centreboard box or keelson in lieu of using traveller track at transom to end of boom attachment fitting.

Installing Novex tension blocks (or similar) and jib sheet winches. Removing oar lock bracket fittings and plugging holes. Installing full width transom track with adjustable stops in lieu of standard. Adding additional pulley blocks along boom from the boom, fixed swivel block along with jam or tension blocks and cleats. Rearrangement of hiking straps.
