That was a low wind day for there and was probably as big as they got that day.
But with that said, they were about 3' wind waves which puts them about overhead, while sitting in an AI (since we don't get all the way down between close waves like that). Very close period, depending on the day. I'm not usually at a stop in them, so I'm not sure of the period. Maybe 3-6 seconds?
That's in an area we sail through between two different wind patterns. Maui has two mountains (volcanoes) and shaped like a peanut. The valley between the two creates a funnel and doubles the wind speed squeezing through it, so on lighter wind days, we sail in the bay for better winds.
BUT, when the wing finally picks up, we need to sail out through the building wind waves (normally 4-6') to get further down the coast, to lighter winds. This can be some of the best sailing of the day! (Also where rudder pins like to break.)
I find it's hard to photograph the wind waves to show their size, but how's these:
if you look just at the water around the boats, you just see a bit of chop, but where did the boats go?
