Cyberhun, do you have & use an anemometer? And you're certainly right about wind-over-tide situations where wave lengths shorten and wave heights increase dramatically. My own experience with reports (including my own) of wind speeds and wave heights is that we tend to overestimate them quite severely--about 150% for wind speed and often 200% (2X) for height, and maybe more. I'm currently reading a GREAT book, "Blazing Paddles" by Brian Wilson. It's his account of his solo circumnavigation of Scotland, in conditions of wind and wave, tide and current that are far beyond what I'll ever attempt. Without in any way detracting from Wilson's skills or accomplishments, though, it is clear that wave heights and wind speeds that he reports are his on-the-spot "estimates" only--guesses really, made under conditions of maximum excitement and stress--and that a paddler, no matter how strong or skillful, could never survive the wave heights (during surf landings and launchings) and wind speeds he reports. But read the book for yourself.
