Editing HMS Endeavour (section)

==Construction==
''Endeavour'' was originally the merchant [[Collier (ship)|collier]] ''Earl of Pembroke'', built by Thomas Fishburn for Thomas Millner, launched in June 1764 from the coal and whaling [[Port of Whitby]] in the [[North Riding of Yorkshire]].{{sfn|McLintock|1966}} She was a type known locally as the "[[Ship and boat building in Whitby|Whitby Cat]]". She was [[full-rigged ship|ship-rigged]] and sturdily built with a broad, flat [[bow (ship)|bow]], a square [[stern]] and a long, box-like body with a deep [[hold (ship)|hold]].{{sfn|Hosty|Hundley|2003|p=41}}

A flat-bottomed design made her well-suited to sailing in shallow waters and allowed her to be [[Beach (nautical)|beached]] for loading and unloading of cargo and for basic repairs without requiring a [[dry dock]]. Her [[Hull (watercraft)|hull]], internal [[Glossary of nautical terms (A–L)#floor|floors]], and [[Glossary of nautical terms (A–L)#futtocks|futtocks]] were built from traditional [[white oak]], her [[keel]] and [[stern post]] from [[elm]], and her masts from [[pine]] and [[fir]].{{sfn|Hosty|Hundley|2003|p=19}} Plans of the ship also show a double [[keelson]] to lock the keel, floors and frames in place.{{sfn|Hosty|Hundley|2003|pp=33–41}}

There is uncertainty about the height of her standing masts, as surviving diagrams of ''Endeavour'' depict the body of the vessel only, and not the mast plan.<ref name="Marquardt"/> While her main and foremast standing spars were standard for her shipyard and era,<ref name=":1">{{cite book|last=Mountaine|first=William|url=https://books.google.com/books?id=a8IzAQAAMAAJ|title=The Seaman's Vade-mecum: And Defensive War by Sea|publisher=W. and J.

If so, this would more closely conform with both naval standards and the lengths of the other masts.<ref name="Marquardt">Marquardt 1995, pp. 19–20.</ref>
