The Landing Craft, Vehicle, Personnel (LCVP) or Higgins boat was a landing craft used extensively in World War II. The craft was designed by Andrew Higgins of Louisiana, based on boats made for operating in swamps and marshes. More than 20,000 were built, by Higgins Industries and licensees.

We had two of them at Great Lakes. The reservist played with them on weekends. Last I heard they had been shipped off to be restored.

Sorry Bruce and Jim. You'll have to dig a little deeper to find this one. Higgins built shallow draft boats before the Eureka.

Let me rephrase the question and that may give you a hint. I'm looking for the name of the hull design, for example, vee hull or catamaran. All of Higgins boats were either built with this type of hull or a modified version of it.

Now, see what you can find. I may have given you too much.

Well, I would say it is a flat bottom planing hull with a spoonbill bow.

hello Kenny,
i do not know what you would call the hull.i will describe what i have found out.
it had 2 hulls,1 on each side with the propeller in a tunnell.i could run at full speed into riverbanks and sandbars with no damage.it only needed 18 inches of water to float and run.
i am guessing it is kind of a catamaran or a pontoon style hull.
cheers,
Bruce

I'll take a stab, Gator...

"A deep vee hull forward led to a reverse-curve section amidships and two flat planning sections aft, flanking a semi-tunnel that protected the propeller and shaft. Aerated water flowing under the forefoot of the boat created less friction when the boat was moving and allowed for faster speeds and maneuverability.

Because of the reverse curve, objects in the water would be pushed away from the boat at a point between the bow and amidships (including the aerated water - only solid water reached the propeller). This allowed continuous high-speed running and cut down on damage to the propeller, as floating objects seldom came near it. The flat sections aft, on either side of the shaft tunnel, actually had a catamaran/planing effect which added to the hull speed."

You are the closest so far so I'll call it "correct." The answer I was looking for is "tunnel hull." The Higgins Wonder boat was designed with a tunnel hull which allowed for shallow draft but took away from the speed and horsepower. The problem was that the propeller was trying to push aerated water (water with air mixed in). It wasn't until one of Higgins' employees forgot to put in a set of hull jigs while build a boat that the modified tunnel was invented. Oh, and the name of this new boat design, Eureka!

hello Mark,
the 2 sources differ on what was the Backbone of the RCN.
the first source states that the Corvette was the it.as the book said the RCN was a Corvete navy.
the other book says that the Tribal class Destroyer was the Backbone of the RCN.
i do not know which one was right.
Cheers,
Bruce

Hmmm...neither one is matching my sources, but close!


Let's make it a bit more specific...These ships were considered as the backbone of the RCN's destroyer fleet at the time aforementioned.............

Canadian River class Destroyer.???


Very Good, Jordan!

"The RIVER class was far from being a homogeneous class of ships, consisting of Royal Navy "C", and other similar classes of ships. SAGUENAY and SKEENA were the first ships laid down for the Royal Canadian Navy, and were adapted from the RN's "A" class. The rest of the ships were purchased used from the RN.

Most or all of the ships started the war off much the same as they were built, and their equipment was gradually revised as the war progressed. First to go was the "Y" mounting 4.7" gun (to make room for additional depth charge storage and Mk.II depth charge throwers) and the aft torpedo tubes (replaced by a 3" HA (high angle) anti-aircraft gun). In some ships, the 3" HA was later relocated to replace the X mounting. The aft mast was removed, but was later replaced with a new lattice mast to support a HF/DF (high frequency direction finder) antenna which was used in concert with other ships to locate U-boat positions when they broke radio silence. In some ships "B" mounting was replaced with a single Hedgehog anti-submarine mortar, although other ships received two smaller Hedgehog mountings to either side of a forward gun and retained both forward 4.7" guns. In some ships, the "X" mounting 4.7" gun was replaced with a relocated 3" HA gun. Several different radars were fitted starting with the Type 286 followed by the Type 271 and 291 sets. Two ships had their Type 271 radar replaced with the newer Type 277 set.

These ships were the backbone of the RCN's destroyer fleet throughout the Battle of the Atlantic. Worn out by the end of the war, all of the River class were paid off soon thereafter."

Your turn, mate!

Hmmm, ok, let me see.....

"This boat and her sister, had watertight, aircraft hangars that housed small floatplanes which were to be used for scouting...."

Name both!
Pay attention to the key words, in the sentence, now mates...

Good guess, but not yet, mate...here's another BIG clue...

"These boats were surrendered to US Navy forces at the end of the war, and taken back to Hawaii to be studied... then, since the Soviets were demanding access to these boats, they were taken out to sea on 31 May 1946 and used as torpedo targets of USS CABEZON.

Going by "boats", I'd also say they are Japanese but of the I-400 class of "carrier"-submarine. They were meant to make attacks on the Panama Canal gates.

Here are the four.

I-400 and I-401 were the two carrier subs.

I-201 and I-203 were also taken to Hawaii and examined.
