I've been in a 10 foot plus chop. I do not want to be there again. It was fun and scary at the same time. The boat took a hell of a beating and so did I. Best speed i could make was 2-5 Knots. When I finally got into the inlet I was headed to I couldn't beleive how exhausted I was or how bad shape the boat was in.

I go by the NOAA bouy data for the area that I boat in on the day I'm boating. The bouy data usually shows dominant waive period and height (which as I recall is the average of the highest waves/swells not the highest).

I don't even bother to try to eyeball it beyond "reflecting pool/flat/bumpy/really bump/going to lunch someplace in the harbor".

NOAA takes an average of the top 1/3 highest waves... the biggest wave around is usually 2 times this average.
so if NOAA says that there are 2-4' waves out every once in a while you are going to run accross an eight. which may be the reasoning fo the over estimation.
