HMCo #418p BPT-30

"Another PT boats was launched with ceremonies Tuesday [March 9, 1943] noon at the Herreshoff Manufacturing Company boatyard in bristol. Mrs. Haffenraffer, of Fall River, wife of Lieutenant A. F. Haffenraffer, U.S.A., who is on service in the Solomon Islands area, christened it. 'The Star Spangled Banner' was played by a workman's band. C. W. Haffenraffer, general manager, spoke. He said the boat was dedicated to the familied of employees in the service. [Though not identified by name, #418p BPT-30 is clearly identified by its launching date.]" (Source: Anon. "PT Boat Launched." Newport Mercury and Weekly News, March 10, 1943, p. 8.)

"... April 12th [1943]: 20th MTB Flotilla (MTBs 291-298) allocated to the Mediterranean from U.S.A. construction. Four boats are now ready for shipment and four will be completed on May 15th. This was later changed, and MTBs 287-294 [all built by HMCo] are being allocated, half for the 18th and half for the 20th Flotillas. This was done because the latter four boats of the 20th will not be completed as early as expected. ..." (Source: Pope, Dudley. Flag 4: The Battle of Coastal Forces in the Mediterranean. London, 1988 (first ed. 1954), p. 79.)

"Building the Motor Torpedo Boats (MTB).
802 MTBs were built in the U.S. during the war to three basic designs; the 87-foot Higgins, the 81-foot ELCO, and the 71-foot Vosper. The Herreshoff yard built the Vosper that was developed as a private design in Britain and first delivered just before the war in 1939. The HMCo received two orders, the first eight in 1943 for transfer to Britain and twenty in 1944 for transfer to Russia.
The boats were powered with three-1350 hp Packard engines each driving through reduction and clutch to a propeller. The design speed was 40 knots and they carried aviation gas for a range of 1500 miles. Two smaller Ford engines provided quiet cruising. The boats were armed with four 50 cal. machine guns, two torpedoes, depth charges and smoke generators on the stern. They were crewed by two officers and eight men.
The MTBs were built in a production line with many pieces formed in quantity from molds and patterns. The keel was white oak and the ribs were built up of plywood and mahogany sawn to shape. The hulls were double-planked mahogany. The decks were mahogany-faced plywood. The hulls were fastened with 43,000 rivets. The contract price per boat was $103,000 and fully equipped they cost as much as a four engine bomber." (Source: Herreshoff Marine Museum.

• El Chico and #418p BPT30 (MIT Museum-made index card)
• Note: The vessel index cards comprise two sets of a total of some 3200 cards about vessels built by HMCo, with dimensions and information regarding drawings, later or former vessel names, and owners. They were compiled from HMCo's early days until 1920 and added to in later decades, apparently by Hart Nautical curator William A. Baker and his successors. While HMCo seems to have used only one set of index cards, all sorted by name and, where no name was available, by number, later users at MIT apparently divided them into two sets of cards, one sorted by vessel name, the other by vessel number and greatly expanded the number of cards. Original HMCo cards are usually lined and almost always punched with a hole at bottom center while later cards usually have no hole, are unlined, and often carry substantially less information. All cards are held by the Francis Russell Hart Nautical Collections of the MIT Museum in Cambridge, Mass.
