How do you calculate mast height?
As a general rule of thumb, the height of a boat’s mast will be somewhere between 1.25 to 1.35 times the boat’s length, for an average of about 1.3 times the length overall (LOA) of the boat. An aspect of 2.5 or lower will be a low-aspect rig; above that is considered a high-aspect ratio.

How do you size a sail?
Hook a long tape measure up to your jib halyard (or top furling swivel on a furler see “Furler Hoist” below) just as if it were the head ring of the sail. Hoist it all the way until it stops at the top. Measure down to whatever point you intend to attach the sails tack to. This will be your MAX.

Mast height is almost always measured from the water.
