PREQUEL: Sailing proa KAURI to Wood's Hole, MA, 01:47 Sailing KAURI to Wood's Hole, MA - prequel to following video, this clip had no sound so added a little music.
notes about "hobby horsing" observed in this video: a few things should be remembered; it happened under some conditions, not all; there are eight people and "cargo" in this video; KAURI was designed and built circa 1980, JZERRO, twelve years later, has a different hull shape.
frame by frame examination shows exactly three cycles of pitching between 13.2 and 17.2 seconds, a frequency of 1.33 seconds/cycle (0.75 cycles/second), with an amplitude of +- 2.1 degrees, as measured between these two frames (14.15 and 15.03):

Leisurely shunt footage at 0:50, moving mylar headsail to opposite end, main sheeted and under way at 01:12, headsail raised and sheeted around 02:22 - NOTE: a speedy shunt is done with a jib on both ends; this day wasn't that kind of a "show", as we had only one jib of this size.
Navigating Woods Hole"Tricky in the best conditions, with little margin for error. [the current] routinely flows through at over 4 knots, and will hit 7 knots on occasion."
