We get to watch ski boat newbies on the Columbia river islands do this often and unintentionally. In summer, Bonneville dam lowers the flow and the river drops 4-6 feet by morning. Morning entertainment is provided by watching stuck boaters over coffee when we are happily anchored deep.

An old Cajun fishing buddy of mine used to say the period between tide changes tide was a "Confused tide" it didn't know if it was coming or going.

The soot blowers are fed by superheated steam (very hot and dry) in a sequence starting low and ending high. The forced draft fans are turned up to supply more air flow to carry off the dislodged soot and that is why it looks like the stack is "blowing."
most of the times they would blow the tubes on the 12 to 4 watch

I got to watch a bunch of bikers (that got hammered the night before), scramble to get their motorcycles out of the surf one morning in Daytona Beach.
Tides, huh.. who knew?.

"That's A Real Bell Ringer", referring to waves that were so steep or jutering to a boat that the boat's bell would ring itself.

Are Pitch, Roll and Yaw proper boating terms, and do they mean the same thing they do when talking about aircraft?

Mr. MC. I think description of aircraft movements are based on nautical terms.

Except the USAF uses "left / right" verses "port / starboard". I learned that the hard way as a Navy AIC.

Yes , there is also heave and surge on the nautical side.

According to Nautical Dictionary, Glossary and Terms directory: Search Results . Hobby horse means, to pitch repeatedly. “In short seas, the boat tends to hobby horse.”

Pitch refers to a single event as the boat pitched up when we crossed the large wake. Hobby horse refers to a repeated cyclical motion that occurs when the wave period matches the resonant or harmonic frequency of the vessel. In extreme cases, severe hobby horsing could result in pitchpoling.

Let's throw this one in also.... phugoid...a relative of pitch

The phugoid has a nearly constant angle of attack but varying pitch, caused by a repeated exchange of airspeed and altitude. It can be excited by an elevator singlet (a short, sharp deflection followed by a return to the centered position) resulting in a pitch increase with no change in trim from the cruise condition...

Phugoid - Wikipedia, the free encyclopedia

It's where United Airlines Flt 232 in the 1989 crash in Sioux City lost it's total flight control system in a DC-10 because the tail engine exploded and took out all hydraulics....yet the pilots landed it with differential engine thrust and playing the phugoid...at least that's the way I remember Captain Haynes lecture going..saw him 2x in that presentation.

Harumph ... a toyboat term that has spread via the internet. Shouldn't be dignified by repeating it.

Mr. psneeld. Airspeed and altitude? I suspect you're a bit phuged-up or on the wrong website....

naw...saw a really fuzzy picture of a phugoid once.... think it's FD...but for the right price....definitely a bluewater vessel. Just don't think you can get away with a propane fridge onboard or surf down them swells through the Columbia bar.

YES , but with no control of the cycle , they were in a Down portion when contacting the ground.

New to me, so perhaps to someone else also.
noun: overfall; plural noun: overfalls
  1. 1.
    a turbulent stretch of open water caused by the wind blowing against a current, by a strong current or tide over an underwater ridge, or by a meeting of currents.
