This sounds like the Jeremie wreck off Haiti, which comes up from time to time. It is not a submarine conning tower, but rather a patrol craft with a steam engine and boiler. Try a search under "Jeremie," and you should find information on the subject. Dan B. Odenweller

Submarines in general, and the Type XXI U-Boat had freshwater storage tanks, and a still to make freshwater. The main purpose for the freshwater system was to produce battery water for the storage cells, followed by cooking and drinking water, and at the end of the list, showers and laundry. Dan B.

Robert - Nice footage, the first couple of seconds shows the gas bubble from the warhead detonation breaking the surface, and lifting the target amidships, breaking her back. Thanks, Dan

Simon - The snorkelers had aircraft altimeters to measure the pressure/vacumn in the boat. Thus as Fritz stated, they cruised at a altitude indication of 1800 feet (actually a vacumn) and the engines automatically shut down at a vacumn which equalled an altitude of 6500 feet. The altimeter was marked in feet, so we "flew" by the altimeter. And yes, he was referring to an F4 cl

Simon - Conjecture, unsupported by evidence, does not history make. Some demand evidence to support the allegations, not a purely American trait. Oh yes, I was born in Venezuela, and consider myself an "American." Dan B. Odenweller

Naval gunfire is generally limited to damage above the waterline, and generally to holes in the hull of the target. There are of course rounds that strike a magazine or a fuel bunker, causing an explosion that tears the hull apart. The torpedo, properly deployed is intended to explode immediately below the target ships hull, lifting the center and breaking the ships back. Thus the torpedo ap

I believe the device is properly referred to as a "tampion or tompion," not tampon. tampion/tompion = muzzle plug for cannon tampon = lint or cotton plug for insertion into a wound or body cavity. Dan

According to the book "Kriegsmarine U-Boats 1939 - 45" by Chris Bishop, the two VIIC boats were: Page 38 - U131 from 1Nov41 to 17Dec41 (lost on patrol), and Page 40 - U821 from 1Nov43 to 31Dec43 (training boat, then on to 24th Flotilla). Both came from the 4th Flotilla. Dan B. Odenweller

The article, about a diver who thinks he has found a submarine off the coast of Chile, has no proof to support the claim. The original work was done in 2002, and a follow up expedition in 2005 apparently failed to find the submarine. Quoting from the article (dated 2007) at the link provided, the statement is made: "La embarcacion llevaba varias semanas tratando de dar con los restos

According to the information in "The Boats" section of this forum, the Second U-Boat Flotilla does not appear to have had any VIIC boats assigned. It did have several VIIA boats assigned, which were: U27, U28, U29, U30, U31, U32, U33, U34, U35, and U36. Dan B. Odenweller

The precise entry is "3,838 lbs (1,738 kgs)". The decimal point is your edit. As I understand the entry, it might be read as: 3,838.0 lbs (British pounds) or 1,738.0 kgs (Metric kilos) assuming the weight was recorded to the nearest tenth of a kilo. Dan B. Odenweller

You are most welcome. The weight listed is 1,736kg not 1.736. There is a difference. So sorry to have wasted your time. Dan Odenweller

Let's see, we now have more U-Boats being built without records of their construction or their completion! Are we sure it isn't a Type XIB, after all there are two hull numbers unaccounted for after the one lying off the NE coast of the United States. I have a sidescan image of what is represented as the one off the US coast. Then we have naval signals found by a cleaner which
