A daggerboard is a retractable centreboard used by various sailing craft. while other types of centreboard may pivot to retract, a daggerboard slides in a casing. the shape of the daggerboard converts the forward motion into a windward lift, countering the leeward push of the sail.the theoretical centre of lateral resistance is on the trailing edge of the daggerboard.. While close reaching the daggerboard design has less of an advantage than when beating, as can be seen from table 2: while close reaching the daggerboard design is expected to sail 0.5 knots faster and 0.75 degrees higher. as the true wind angle approaches 90
