My apologies for posting a message that just quoted a message, my ISP had some clever new ways to disrupt email service today. Dave, in answer to your question, I don't recall a source for the NOAA quote. Only that when I read it, I made a mental note of it because it had explained why a forecast for 4-6' seas was observed as 8-10 by everyone on the boat. (i.e. 8' from trough to crest is 4' from the middle.) Looking online today, I only got as far as about.com stating that the DOD definition is crest to trough. Dunno.
