HMS Endeavour off the coast of New Holland by c. Contents • • • • • • • • • • • • • • • • • • Construction [ ] Endeavour was originally the merchant collier Earl of Pembroke, built by Thomas Fishburn for Thomas Millner, launched in June 1764 from the coal and whaling port of in, and of a type known locally as the Whitby Cat. She was and sturdily built with a broad, flat, a square, and a long box-like body with a deep. A flat-bottomed design made her well-suited to sailing in shallow waters and allowed her to be for loading and unloading of cargo and for basic repairs without requiring a. Her, internal floors, and were built from traditional, her and from, and her masts from.
Plans of the ship also show a double to lock the keel, floors and frames in place. Some doubt exists about the height of her standing masts (excludes top and gallant masts ), as surviving diagrams of Endeavour depict the body of the vessel only, and not the mast plan. While her main and foremast standing spars (excludes top and gallant masts ) are accepted to be a standard (standards differed from shipyard to shipyard and country to country ) 69 and 65 feet (21 and 20 m), respectively from an annotation on one surviving ship plan in Greenwich NMM ZAZ6594 which records these lengths has the mizzen as '16 yards 29 inches' (15.4 m). If correct, this would produce an oddly truncated mast a full 9 feet (2.7 m) shorter than the standards of the day. Late 20th-century research suggested the annotation may be a transcription error and should read '19 yards 29 inches' (18.1 m), which would more closely conform with both the naval standards (which standard?
) and the lengths of the other masts. A more recent critical review of contemporary sources doesn't require a supposed typo in 1771 to explain this shorter measurement for the mizzen whilst at the same time offers supporting evidence of its cap being at the taller supposed normal height. Sydney Parkinson's sketches and paintings of Cook's Bark Endeavour along with the 1771 Woolwich Yard Bark Endeavour spar measurements in Greenwich NMM ZAZ6594, and other contemporary sources suggest that the shorter mizzen mast was not stepped in the hold/keelson, but instead was stepped in the lower deck 10 ft above this as was sometimes done. Great basin serial killer. This would bring its standing height at the cap to within a supposed normal height of around 8– 9 ft below the main mast cap and approx 5.5 ft below the foremast cap when comparing the heights of the standing mast tops (excludes top and gallant masts ) from the level of the water line.
Whereas the shorter mizzen stepped in the hold on the keelson instead of the lower deck would make the standing mizzen cap 18 ft below the main mast cap which is clearly not the case when critically examining Sydney Parkinson's drawings and the contemporary painting titled HMS Endeavour off the coast of New Holland, by Samuel Atkins c. 1794 at the top of this page.
Zooming this painting also reveals that the position of the mizzen channel is forward to inline with the mast which it is when looking at the angle of the mizzen chainplates on the original as fitted draught NMM ZAZ7844. Using these mizzen chainplate angles from this as fitted draught, it is possible to extrapolate where the top of the standing mast could be and combined with the similar shroud angles Sydney Parkinson drew in his sketch of the larboard quarter of Endeavour support this theory of the shorter standing mizzen stepped in the lower deck which would make its standing cap 10 foot higher than if stepped in the hold. The replica standing mizzen is built to this shorter measurement and stepped in the hold on the keelson, as is the model in the in Greenwich. There is a difference between the height of the mizzen fore-and-aft spar in the contemporary painting of Earl of Pembroke before the naval refit of 1768 by Luny (below) and its position on the replica in the photographs, compared to the height of the lowest spars on the fore and mainmasts. Purchase and refit by the Admiralty [ ] On 16 February 1768, the petitioned to finance a scientific expedition to the Pacific to study and observe the 1769 across the sun.
