George.
I have yard number 1 as Golden Sunset. I have 42 ships built before that at Coxgreen (near present day Nissan factory), either by Doxford, Stothard and Boyd or later by Doxford and John Crown at Southwick. Doxfords opened their five berth west yard in 1870 and the first ship their was Amy, and I have this as yard number 38 in December 1870.
The 42 ships that predated yard number 1 have no yard numbers attached so for the sake of computer sorting I have numbered Hesperia ( for E Jarvis, Salcombe in July 1874),the ship prior to Golden Sunset as -1 and the earliest recorded ship William and Catherine ( for William Doxford in April 1837 as yard number -42)
Agincourt that you asked about, I have as yard number -6 for Cator, London in January 1863
The minus prefixes are purely my invention to maintain sequential order on Excel spreadsheets
I have attached a copy of my list for what its worth. I have one source that claims the first ship at the west yard yard was -17 the Ann Taylor built in 1858! So you must be careful about whom you trust.
Please bear in mind that my lists are the work of an enthusiast not an authority and because of the many conflicting records that I have, I have often been "Confused.tom" Any corrections would be most welcome. Use this information as you please. the more that see it the better the chance of it becoming accurate and reliable. This list was compiled in 2006 and nothing has been done to it since then.
Accuracy must be a pre requisite, not an optional extra!!
