whats the trick to this MurphyBed/Desk mechanism?

How to build a pipe berth.

 

I could see that on a skimmer, most subs have the off-going watch sweep up before racking in with field day every Saturday morning where both off-watch sections are turned out and turn too. The only days for reveille were Saturday and when you were setting the Maneuvering Watch.

 

I never could identify well with submariners, though certainly respected them. They seemed alien to me after one told me there were only two types of vessels. Subs and targets.

I feel certain that the boatswains mate of the watch, must have piped close all ports and weather deck doors before the deckforce hosed the sub down with freshwater. Your screendoors wouldn't deflect the hose spray very much.

Probably everyone aboard subs is a watchstander. Only been aboard museum subs, so don't know. Aboard surface vessels, more than half the personnel are day workers. Reveille is for the day workers. Watchstanding reliefs are individually awakened by the bo'suns mate of the off going watch.

 

But remember that there also is no such thing as a friendly sub, which is why operational zone management is so important.
But getting back on topic, below is a photo of a "spacious" berthing compartment (SSBN I think). A rack is typically 72" long, 24" wide with 28" between pan bottoms. The pan locker is 4" deep and the collision mat is 2" thick giving 22" of shoulder space and means that the top rack is 62" off the deck (not as bad as the old 4 or 5 high pipe racks). Additionally, at the foot of the rack is your EAB locker and in the overhead of the rack was a light, fan, and vent. The top rack would typically get real cold because that's where the AC vent was, and at 6'-4" and broad shouldered, I generally preferred to sleep in the torpedo racks for the length and vertical space.

And many classic saloon settee backs would swing up on chains to form upper and lower sea berths.

Never been too much a fan of typical backpacking hammocks that close around you, but hammocks with spreader bars are OK. Recently a hammock that is also part "tensile tent" came out that relies on the width of the tree to spread and create 4 point suspension. I guess I could do something similar in the van suspended by the four corners of the roof sheetmetal. Something like this latch beaten into shape to spread the load with 8 big self-tappers at each point.

Copy the astronauts. No up or down in space, so they insert themselves in a wall hung bag.

 

I take it that individuals over 72" are discouraged from taking sub duty.

 

Age discrimination!

 

You'd think...but...seeing an average crew you would be surprised.

 

Suspect Hoyt is referring to WW2 diesel sub crew height limitations, from some movie. Don't recall the movie, but seem to recall that information in a movie script. Was it accurate? ¯\_(ツ)_/¯

 

I just assumed it due to the bunk dimensions.

 

See what happens when I ASSUME?

 

The double bunk in my dad's travel-trailer was replaced with a twin hammock after my mom complained about the weight of the double-bunk.

It had three lengths of about 2 inch gas pipe. Each fit in its own sleeve. It was a whole lot easier to stowe, having no mattress and just sleeping-bags.

The three pipes were held apart by a board on the wall at each end which was notched to receive the ends of the pipes.

I found it quite comfortable.

 

don't quite understand. any chance of rough sketch?
