HMCo #610p PT 440

"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.

Note: The transcription of the HMCo Construction Record by Peter Vermilya and Maynard Bray was performed independently (and earlier) than that by Claas van der Linde. A comparison of the two transcriptions can be particularly useful in those many cases where the handwriting in the Construction Record is difficult to decipher.
