Windsurfing

Windsurfing off Hale Kai is not for novices. The wind is often easterly (blowing you away from shore), and very light within 100 yards of the shore, making it difficult to get out, and even harder to get back. And water starts are basically impossible in those light winds. But if the trades are blowing 20 knots or better, I can consistently get out on my larger standup board, inch out past 100 yards, then have the whole Pailolo Channel to myself with fresh wind (but take care not to make turtle soup). In 20 years I've seen lots of porpoises, but only one innocuous reef shark.

Cell phones don't work well when wet, so I stay within eyesight of shore.
