Place: Kaoi Surf (Fukuoka, Japan) Time: 12:00 to 14:00 Sail size: 5.8 m2 → 6.3 m2 Board volume: 94 L Wind: Northeast, Right Cross-onshore Sea conditions: Annoying floating seaweed I started with a 5.8-sq-m sail, but the wind turned out to be not sufficient, and I planed only 100 meters. Out of frustration, I decided to use a 6.3-sq-m sail. While I was changing the rig, the wind got weaker. I misjudged the wind today.
