The HNSA is a sort of online clearinghouse for information about museum ships and related facilities. As they put it on part of the website:
We promote visiting the world’s historic naval ships and advocate for the need to save these important vessels for future generations so that they may continue to proudly serve their countries in honor of those who served and continue to serve at sea.
There’s information about preserved ships around the world. In a brief visit, we saw that this rare (2 built) classified-until-2011 OSS infiltration semisubmersible boat codenamed Gimik, is just two hours away in Massachusetts…
…but we also looked at pages for other vessels, like BAP Abtao, a sub that was built by Electric Boat for Peru and is on display in that Andean nation after a career that included over 5,000 dives and the rescue of the crew of another Peruvian sub sunk by collision.
We particularly like their reference library.
So what’s there? How about the text and some illustrations of a 1945 PT Boat manual, Know Your PT Boat. Written in a style reminiscent of the German Panzerfibel with cartoon illustrations, it gives the sailor newly assigned to PT Boats an overview of its systems and operations. Unfortunately, this version has been slightly bowdlerized; cartoons that made racist caricatures of Japanese have been removed. (And some haven’t).
Know Your PT Boat even deals with maintaining the refrigerator:
Your refrigerator can make ice cream, ice cubes, and frozen delights (especially good is frozen fruit cup). Once a Jap bullet punctured a refrigerator unit and drained it of all its freon. Several of the boats then decided to put armor plate about the refrigerator. So you see it’s really very important, for it contributes to the living comforts which are all too few in the Area. Your refrigerator pump and motor need servicing. Don’t let them wear down or overheat. To keep meat, your refrigerator must be in top shape. It is rare to have fresh meat and when issued it comes in 100-pound quantities. Hence the necessity for a good freeze or reefer. Have a drip pan properly placed or the meat juices will leak into the bilges and in a week you’ll be accused of carrying a dead Jap around in your bilges.
Of course, WeaponsMan.com readers will probably be most interested in the gunnery.
Don’t be like one boot who ducked down inside his “armored” turret during an attack and then later when he discovered that the turret was made of 3/4″ plywood he fainted.
Aside from the actual firing of the guns the important thing is the preparation. Everything must be in perfect operating order. “Be Prepared” is not just a Boy Scout motto, it is the watchword of every fighting ship. You can make no excuses to the Japs for a jammed 50, a weak drive spring, or a 20-mm. magazine with no tension on it. The guns must fire when you want them. They will, only if you have done your drills so that you can do everything automatically. Strip your guns regularly, exercise the springs, and make other routine checks. Then you will know in times of action how to put tension on a magazine and how to blind load.
37-mm. Gun.-To the “Barge Hunters” this is a fondly loved gun. Its flexibility, ease of firing, destructive power, and flat trajectory make it a grand gun against targets at moderate range. A 37-mm. seldom jams of itself. The few jams that do occur are usually traced to faulty ammunition.
20-mm. Gun.-This gun is so powerful that it has earned the name “cannon.” When you hit something with a 20-mm., you really do some damage. Not small punctures but gaping holes are the marks left on the enemy by this powerful shell. Aside from the usual preparation and care of a 20-mm., the following are helpful hints:
- Precaution must be taken in clearing a 20-mm. jam. Always have a bucket of water on hand. When a jam occurs, souse the breech and barrel. If you cannot get the projectile out in a few seconds, secure the gun for about 5 minutes. In any case, never stick your nose or fingers into the breech. Keep clear and use your ram rod.
- Practice cocking of the 20-mm. It is a tricky operation and should be done speedily and with ease, especially in the dark. It is the only war to clear a jam, and to get the gun set to fire again.
- The loader must get a rhythm in his task and eliminate groping at night. The gunner and loader who drill in the daylight with their eyes closed are doing a wise thing. The magazine is quite heavy. On a high trunnion gun, the loader should be both strong and tall.
- Be sure that prior to any imminent action all magazines are on full tension at 60 pounds. If your magazines have been in use a long time, it is wise to pull out a few rounds before loading, but be sure you still have on the full tension. This precaution will give the last few rounds in your magazine an extra push and will prevent jamming.
There’s a lot more in Know Your PT Boat, but it’s only one of the features to be found on this site.
