Waves that have reached the maximum size possible for fetch, wind speed and wind duration are referred to as being fully developed.

Waves that have reached the maximum size possible for fetch, wind speed and wind duration are referred to as being fully developed.
what is the difference between a refraction and a wave refraction.
AND
What is a sweep. here
This is the vertical distance from still water level to wave peak. (Approximately half the height of the wave)
Also I agree that the Great Lakes can offer some of the toughest water out there. more
"For example, the Port Everglades inlet at Ft. Lauderdale has adequately deep water to the south outside the channel. Since the prevailing winds are east/southeasterly, this wide deep inlet can produce a very nasty tide rip. However, it is easily avoided by leaving the market channel to the south, but very rare is the captain I see who ever does this. Instead, they subject us to heavy bashing and plumes of spray for nearly a mile beyond the jetties." more

There are times when the trouble spots cannot be avoided, so that good seamanship calls for making preparations for entering areas of dangerous waters, as well as knowing how to pilot the craft through them. Just because you have a fast boat doesn't mean that you can escape from trouble quickly. Once you pilot a boat into troubled waters, you become trapped by them, and only good seamanship will get you out. Lacking such skills, you days on Earth may come to an end. [links]
A deep water inlet with a strong tide rip and moderate seas can produce conditions like this. Do you know how to handle it? What would you do if encountering a situation like this? more
4. When encountering rough water, take the time to be observant of what is happening around you. Use the opportunity to practice and learn boat handling skills.
One of the things that makes boating so very interesting is that there is so much to be learned. Another is that it can be dangerous, which, for the adventurous just adds some spice to the banquet. The socially oriented recreational boater is unlikely to ever learn much in the way of seamanship; he owns a boat as an avenue for recreation, something to do with family and friends. It's a whole different ball game for the true boater, for whom boating is a hobby or avocation. Him we can call the true yachtsman whether he owns a small outboard or a mega yacht because his real interest lies in challenging the sea, be it an ocean, bay or river. more
Sea state is the term used to indicate, not only wave height, but is also a description of wave life. As winds are increasing and building up wave height, as at the start of a storm, waves will be shorter and steeper. The shape of waves is determined. in part, by how long the wind is blowing at a particular speed. Waves will remain steep as long as wind speed is constant or increasing, but as soon as the wind slackens, wave height and duration will begin to decrease. These waves will be far more comfortable than the waves while winds are constant. here
In extreme turbulence, your aircraft is violently tossed about and practically impossible to control. Extreme turbulence can cause structural damage or even break apart your airframe. The airplane below flew into a squall line and experienced extreme turbulence, resulting in a mid-air break up. here
Moderate chop is similar to light chop, but it's more intense. Moderate chop has consistent bumps or jolts, with little to no change in altitude or attitude.
So there you have it! The next time you're up in turbulence, you'll know how to give a pilot report to ATC like a pro. more
Light turbulence is a series of momentary, slightly erratic changes in your altitude or attitude. When you're in light turbulence, you might feel a slight strain against your seat belt or shoulder straps. Small unsecured objects might get dislodged in your plane. If you could, it would be easy to walk around the cabin with little or no difficulty (except for the fact if your in a GA airplane, you probably can't walk around anyway). here
Moderate turbulence consists of changes in your altitude or attitude, but your aircraft remains in positive control at all times. You'll feel a definite strain against you seat belt or shoulder straps. And if you have unsecured objects in the cabin, they'll become dislodged. If you could, walking will be difficult in your cabin.
