There are almost no vessels anymore that have actual FIXED PITCH screws. That is a matter of efficiency. Almost every non-controllable pitch screw, is a variable pitch, as the pitch of each blade gradually changes along the blade. (To be simple, each blade has a curve to it). A true fixed pitch has flat blades, which are very inefficient.

Just another set of terms that is slowly using it's meaning as the original terms no longer aply.

Thanks Master Chief for explaining this.

DLo required me to pull out Uncle Nate's.

How about these two:

1) Describe the significance of 6º, 12º, and 18º below the horizon.

2) What are the four versions of the square knot and what are their purposes?

POSH-"Port Out, Starboard Home"

I am assuming that Ceilings and floors are found in the yoeman's office.

Ceiling = the top of a cargo hold.
floor = the opposite

2) What are the four versions of the square knot and what are their purposes?

6 = Civil Twilight = horizon clear and bright, stars visible.
12 = Nautical Twilight = horizon vague.

18 = Astronomical Twilight = full night.

# 2, later, please, for the answer.

Wasn't POSH one of those Spice Girls?

Why the heck don't they make the back end of sportfish boats a little round since they often are backing into the seas while fighting a fish on the line? Anyone?

Don

Maybe the reason is a matter of speed. Most sportfishing boats want to get some place else ASAP. Most sport fishermen,IMHO, are Type A personalities. They probably would get the Heebee-Jeebees on a 8 knot trawler yacht.

An aircraft circles your vessel three times
while gunning its engine, and then heads off in
a northwesterly direction.

What is the pilot signaling?

The pilot wants you to follow him in that direction as someone needs assistance.

That depends! Was his last pass of the bow or stern? (The stern meaning forget the previous time I went off your bow)

Excellent! That's it.

Here's another:

This common nautical term describes the body of water next to a pier or wharf where boats or ships float.

Master Chief, you are so correct.

Would you like to do the UNSCRAMBLE?

CORRECT!

We all know the reef and granny knots; most people hear about the thief knot sooner or later on a midwatch. The grief knot (also what knot) serves no real purpose. Like the thief knot, the bitter ends are opposed/diagonal. Its claim to fame is that it can easily be undone by pulling on the standing parts. It is sometimes used by magicians.

CORRECT! Specifically, when the sun is 6, 12, and 18 degrees below the horizon. Rule of thumb: twilight for the civilian, mariner, and astronomer.
