To achieve balance, the correct lead of CE over CLP (=CLR?) as a percentage of LWL is 7-12 per cent for a schooner; 11-14 per cent for a ketch; 12-15 per cent for a yawl; and 13-17 per cent for a sloop or cutter. Dave Gerr (The Nature of Boats)

In flat-bottomed boats, putting the CE directly over the CLR seems to achieve good balance just about every time; however it is different in boats with a deep vee-section near the bows. Jim Michalak.

Sail Balance, again. The shape of the leading edge of the keel is one of the chief factors in determining the balance of a boat. If the edge is sharp the forward part of the boat tends to bite into the water and hold its position, whereas a a rounded or blunt leading edge will tend to slide off sideways when a boat is sailing to windward - so what we might call the true centre of resistance is further forward inn a boat with a sharp leading edge than it would be in the case of one with a blunt leading edge. In other words, we can't really know where the centre of balance is likely to be without doing tank tests. F S Kinney .

The diameter of a traditional solid wood round boom should be of the boom length. For a loose footed sail, it should be maximum, tapering to at the ends. The diameter of a solid wood gaff should be - of gaff length. John Leather.

The best proportions for a gaff mainsail are luff , head , leech , foot, . The angle of the gaff to the centerline of the mast should be 30 degrees. The rake upward of the boom should be 6 degrees. If a topsail is to be carried, then the angle of the gaff should be eased to about 42 degrees. John Leather.

The simplicity of the cat rig is a recommendation in itself. William and John Atkin .

For singlehanding a large boat and therefore obliged to split up the rig, I would have a ketch with the area of the mizzen about two thirds of the mainsail, and the mizzen mast stepped about as far forrard as practicable. There would then be some chance of the vessel working to windward under mizzen and headsails in heavy weather. F B Cooke.

The permanent backstay should be designed to clear the end of the boom regardless of how high the latter may rise in jibing. William and John Atkin.

I believe only a solid stick (mast) has any place on a gaff-rigged boat. Oliver Tantanen.

A good figure to aim at for important shrouds is to have the cap or upper shrouds make an angle of 14 to 15 degress with the centre-line of the mast. John Illingworth.

Sail area is modest in the small cruiser simply because the buyer cannot be trusted to reduce sail to a safe area when it begins to blow. Des Sleightholme.
