How much mark-room am I actually owed at the mark?
Mark-room is room for three things: to sail to the mark when that's your proper course, to round or pass it on the required side, and to leave it. There is no fixed maximum and no minimum — the space depends on the existing conditions: wind, sea state, your speed, your sails and your boat. Light air on a flat lake, barely a boat-length; a steep sea with the mark pitching, more than a hull-length. You're owed what you actually need to do it in a seamanlike way.
