Nice Day to Not be Sailing Off New England

It’s a nice day to not be sailing off the coast of New England. The following graph shows wave heights from a live data buoy about fifty nautical miles southeast of Nantucket in the current storm.

    Bouy data? I thought you were giving us a preview of tomorrow’s YHOO chart…

    The distance between wave peaks is important too. I once skippered in a sailboat race in Da Nang Harbor after a typhoon had been doing its work offshore. We were in boats with roughly a 19′ mast (Rhodes 19 or Lightning) and from the peak of a wave you couldn’t see the top of the mast of a boat in a trough. But the peak to peak distance was something like 100 yards, so it was sailable. The wind was heavy but very steady. I was able to plane on the peak of a wave a few times, and it wasn’t a planing hull boat.
    The energy in a wave is proportional to some power (third?) of the peak-to-peak distance, so to build up that kind of power it takes typhoon type winds working over a fetch of hundreds of miles. Off Nantucket doesn’t sound like so much fun.

    Am I like missing something ? This station is like 200NM off Cape May, NJ

    Ok, granted I never venture away more than 20NM off the Boston harbor, but still, I fail to understand how 200NM away wave is going to affect New England sailing experience.
    Some explanation ? (Assuming there is one, and it wasn’t a typo)
