Apologies for the delay.
It's been a mixed bag of weather this week: rain, some snow flurries, and then yesterday glorious sunshine! The wind also switched to the south, which helped to flatten the sea because of the shelter afforded by the Noto Peninsula, about 40nm away.
The original Windsurf Round Japan sail (Loft Switchblade 8.5, sadly no longer with us) lives on in the form of a camber inducer turned into a camera mount, and I used it to grab some video. I sailed about 15 nm and retired for the day at Itoigawa with the wind strength already beyond sensible.
