Nice sailing day, steady at 15. After lunch wind switched from 15 to 25 steady, in about 5 minutes. Twenty-three, gusting to 30. Ripping alone on jib alone (after Happy wisely suggesting dropping the main). Nicely balanced helm, beam-reaching at 7 knots, touching 8. Had to turn north directly into the strong winds to make final approach to this new harbor for us. Luckily it was deep enough! Long, tiring day.
