anyone any knowledge of hm survey ship endevour?


It all depends which Endevour you are interested it. Capt Cook back in the 18th century surveyed on HMS Endevour. In the 50/60's we had a converted inshore mine sweeper employed on survey duties. The most recent antartic supportl vessel and its predecessor at the time of the Falklands War were also HMS Endevour's.

Just do a Google search on "HMS Endevour" and pick out the ship that grabs your interest.
