s. The PT boat squadrons were nicknamed "the mosquito fleet".

The PT Boat used in World War II was built using classic "planing-type" hull forms that were inspired by the racing boats that dominated the world boat racing circuit and set water speed records between the wars. However, the original pre-WW1 "Torpedo boats", developed in the early 20th century, were originally designed using "displacement-type" hulls rather than planing type hulls. The original purpose of both types of boats were similar to each other, namely to be an inexpensive way to deliver torpedoes which could destroy capital ship

s, which themselves were originally created as a defense against torpedo boats. Indeed, the name "destroyer" is actually a shortening of the name "torpedo boat destroyer" from the World War One era. Though many would question the military effectiveness of the boats in this role, their psychological impact in deterring Japanese attacks was significant. The Navy's impetus for building the PT boat fleet was for both economic and material reasons. Ten PT boats could be built for the cost of one modest-sized destroyer escort. Another reason was a shortage of steel, which had to be conserved for building larger ships, at the beginning of the war. Towards the end of the war, the US was able to build a massive naval fleet, and the wood construction of the PT boats enabled more steel to be used for that purpose. Later in the war, the boats were much more effective as gunboats against targets their own size, such as armored barges that the Japanese used to shuttle troops and supplies between islands.

History

In the late 1930s, the US Navy requested a competitive bid for several different concepts of torpedo boats. This competition led to eight prototype boats built to compete in two different classes. The first class was to be for 55-foot boats, and the second class to be for 70-foot boats. The resulting PT boat designs were the product of a small cadre of respected naval architects and the Navy.

). This success in small-boat building was followed in the 1930s with 30-ft to 57-ft "Veedettes" and "Flattops", which were gasoline-powered boats that set the highest standard in a golden era of boating. This small-boat experience helped Elco obtain a contract for 10 boats based on the 70-foot Scott-Paine Model PT Boat. These 70-foot boats were tested and determined to be too light for open sea work, but Elco got a contract for 24 larger boats based on a lengthened 77-foot design.

The design competition and seaworthiness trials for the PT boat was nicknamed "The Plywood Derby" and took place prior to the United States entering the war, in early 1941. The Navy Department held these competition trials around New York Harbor. This was a shakedown to see which company would be contracted to build the Navy PT boats. At the completion of the trials, the Navy was impressed with all three designs, with the Elco 77-footer coming out on top, followed by the Higgins 76-footer and Huckins 72-foot boat. Although Elco came in first, the Navy saw the merits of the other two boats and decided to offer all three companies contracts. Elco received the lion's share of the contract (385 boats by the end of the war), Higgins was second (199 boats by the end of the war) and Huckins with the smallest contract (18 boats by the end of the war, none of which would see combat, being assigned to home defense squadrons in the Panama Canal Zone

) boats of the PT-95 class, the 80-foot (24.4 m) Elco and the 78-foot (24 m) Higgins boats became the standard American motor torpedo boats of World War II. By war's end, more of the 80-foot Elco boats were built than any other type of motor torpedo boat (326 of their 80-foot boats were built). Elco also produced 49 of their 77-foot boats and ten 70-foot boats.

Elco

The Elco Naval Division boats were the largest in size of the three types of PT boats built for the US Navy used during World War II. The 80-foot (24.4 m) wooden-hulled craft were classified as boats in comparison with much larger steel-hulled destroyers, but were comparable in size to many wooden sailing ships in history. They had a 20 ft 8 in (6.3 m) beam

 planks, with a glue-impregnated layer of canvas in between. Holding all this together were thousands of bronze screws and copper rivets. As an example of the strength of this type of construction, the hull of the PT-109 was strong enough that airtight compartments kept the forward hull afloat for hours even after being cut in half by a destroyer. Additionally, damage to the wooden hulls of these boats could be easily repaired at the front lines by base force personnel.

Hull shape was similar to the planing hull found in pleasure boats of the time (and still in use today): a sharp V at the bow softening to a flat bottom at the stern. PT Boats were intended to plane at higher speeds, just like pleasure boats, but with the huge engines and the fuel they required, this rarely happened, even on smooth water. If high-speed operations were attempted on rough water, some hulls simply broke up. In 1943, an inquiry was held by the Navy to discuss planing, hull design, and fuel consumption issues, but no major modifications were made before the end of the war. (Wooden Boat Forum)

However, using the older 4M-2500 engines, increases in the weight of the boats due to more weaponry offset the potential increase in top speed. Fuel consumption of these engines was phenomenal; a PT boat carried 3,000 gallons (11,360 liters) of 100 octane

) per hour (200 gallons (760 l) per hour for all 3 engines). However, at top speed, consumption increased to 166 gallons (628 l) per hour per engine (or 500 gallons [1,890 l] per hour for all 3 engines). At the top design speed of 41+ knots (rarely possible in service, in the absence of hulls and engines in perfect condition), the 3,000 gallons of fuel would be used in only about 6 hours.

ese guns could and did result in catastrophic explosions with near-total crew loss. They feared attack by Japanese seaplanes, which were hard to detect even with radar, but which could easily spot the phosphorescent wake left by PT propellers. Bombing attacks killed and wounded crews even with near misses. There are several recorded instances of PT boats trading fire with friendly aircraft, a situation also familiar to U.S. submariners. Several PT boats were lost due to "friendly fire" from both Allied aircraft and destroyers.

Initially, only a few boats were issued primitive radar sets. In the Battle of Blackett Strait (where PT109 was lost), only three PTs (the section leaders) had radar, and they were ordered to return to base after firing their torpedoes on radar bearings. When they left, the remaining boats in the section were virtually blind and without verbal orders, thus leading to more confusion. This may have contributed to the events that resulted in PT-109's loss. Later in the war, as more PTs were fitted with dependable radar, they developed superior night-fighting tactics and used them to locate and destroy many enemy targets. The boats would lie in wait to ambush a target from torpedo range (generally about 1000 yards ), but once their position was given away by the torpedo launch, they would have to lay down a smokescreen from stern-mounted generators, to help conceal their escape from ship-mounted searchlights or seaplane-dropped flares, illuminating them for heavy-caliber guns, which PTs lacked. Depth charges were sometimes used as a last-ditch confusion weapon to scare off pursuing destroyers. Gunboat versions mounted extra armor, though tests showed this was not very effective.

PT boats lacked the refrigerators for meat, milk, butter and eggs of larger ships, so crews depended on the ingenuity of their cook, who might also be quartermaster and signalman, and what he could do with Spam

. During the D-Day invasion, PTs patrolled the "Mason Line", forming a barrier against the German S-boats attacking the Allied landing forces. They also performed lifesaving and anti-shipping mine destruction missions during the invasion.

Perhaps the most effective use of PTs was as "barge busters". Since both the Japanese in the New Guinea area and the Germans in the Mediterranean had lost numerous resupply vessels to Allied airpower during daylight hours, each attempted to resupply their troop concentrations by using shallow draft barges at night in very shallow waters. The shallow depth meant Allied destroyers were unable to follow them due to the risk of running aground and the barges could be protected by an umbrella of shore batteries. PTs had sufficiently shallow draft to follow them inshore and sink them. Using torpedoes was ineffective against these sometimes heavily-armed barges, since the minimum depth setting of the torpedo was about ten feet (3 m) and the barges only drew five (1.5 m). To accomplish the task, PTs in the Mediterranean and the Pacific (and RN

. There has been some doubt shed on whether this finding is in reality from the PT109, due to 2 other PT Boats were lost in this general vicinity at other times. Ballard was reluctant to dig into the sand beneath the tube to verify if it was indeed still attached to the wooden hull of the boat. He also never found the 3 engines which should have been nearby, nor anything else. Basing the discovery of wreck of the PT-109 upon the finding of a single torpedo tube has led several authorities to cast doubt upon the entire affair.

PT boats today

At the end of the war, almost all surviving US PT boats were disposed of shortly after V-J Day. Hundreds of boats were deliberately stripped of all useful equipment and then dragged up on the beach and burned. This was done to minimize the amount of upkeep the US Navy would have to do, since wooden boats require much continuous maintenance, and were not considered worth the effort. The level of gasoline consumption relative to the boat's small size also made their operational expense impracticable for a peacetime navy. Much of this destruction activity occurred at PT Base 17, located on the island of Samar

Recently, in Feb 2002, another 80-foot Elco boat ex-PT-486, now called "Schumann Sails Big Blue" was discovered operating as a sightseeing boat out of Ottens Harbor, in Wildwood, NJ. There is also ex-PT459 located in Rondout Creek, near Kingston New York, that Rob Ianucci has obtained for possible restoration. It has been cut down to 65 feet and is highly modified into a fishing trawler. He plans to try and restore it after further study. Also as part of this group is ex-PT615, originally a boat of RON 42, which was commissioned after the war ended, the 615 was returned to ELCO after being sold and was heavily modified into a yacht. The 615 was then leased to actor Clark Gable. He named the boat TARBABY VI, he used it through the 1950s, the boat was serviced by ELCO and stored there when not being used. The boat was later sold a number of times. In the 1990s it was for sale again now known as GABLE'S DREAMBOAT. 615 was eventually obtained by Rob Ianucci for possible restoration. It is also located at Rondout Creek, near Kingston New York.

. There in Kingston, PT-728 serves as a tourist attraction, giving up to 49 tourists the chance to ride on a "PT boat". This boat is the only US Coast Guard regulation-approved boat that is licenced to take passengers for hire, and is the only surviving US-built Vosper design. Some may remember the boat used as a movie prop in the "McHales' Navy" TV show, "PT73". Up until the mid 1990s, the Vosper boat hull that was used in the TV show existed in private hands in Santa Barbera, CA. The owner kept it sea-worthy and ran it around from time to time. Unfortunately, the boat got caught out at sea in a sudden storm and sank.

The 1963 movie PT-109 used what appears to be a small fleet of three or four Elco boats. The engine telegraph even shows the Elco name, and while at first, or even second glance (for the uninitiated) the boats look like real 80-foot Elco boats, the generally accepted belief is that the boats were converted from Air Force Crash Rescue Boats. Another possibility from observing the rounded transom suggests that these were converted Coast Guard boats, but this is highly improbable as the USCG vessels were round-bilge and not hard-chine.

It is worthy of note that two of the experimental PT-Boats also still survive, ex PT-3 in Pennsylvania and ex PT-8 in Louisiana. The PT-8 was built entirely from aluminum but did not pass the speed acceptance criteria for use as a PT Boat for the US Navy due to its weight. It was reclassified as a harbor patrol boat for the duration of the war.
