To be a truly close reach the wind angle has to be forward of the beam and that generally requires a jib or specially cut reaching sail. On a tight spinnaker reach the apparent wind angle is forward of the beam because of the boat speed vector, but the true wind is usually at just about 90 degrees. |

The "official" point of sail is with reference to the true wind, ie the wind as seen by an unmoving observer. The apparent wind, which is what the sails & sailors on the boat feel, is "bent" toward the bow by the boats speed. For example, ice boats are always going upwind by apparent wind even when they're going downwind by anybody else's point of view. ...

Depends on how fast the boat is ![]() In one small boat race a few years ago, we were on the same race course as the then-new Intra 20 cat, which flies a small flat spinnaker-like sail from a bowsprit on the downwind legs. They rounded the windward mark somewhat behind us, set this sail, and roared past us at a lower angle (relative to the wind) but with their sails pulled in almost as tight as for a beat. By the time we got to the gybe mark, they were at the leeward mark. BTW not sure it was clear from the context my earlier post should have said 'reaching STRUT' which is a piece of gear I've always found such a PITA that my fingers will barely type the word.
