Field log
Chart the hunt before the tide moves the box.
Drop a hunting zone, keep a quarry of ships, and write the dossier while the position is still a circle you can search.
How a hunt is kept
Four marks on the same expedition.
-
01
Drop a hunting zone
Name the water, set a center, and hold every possible hull inside a circle you can actually search.
-
02
Quarry the ship
Record the year it sank, depth, coordinates, confidence, and whether the site is open for diving, technical only, or a permit or war grave. Move the hunt from target to search, then found or not found.
-
03
Write the dossier
Keep history, search notes, sonar, and the dive itself together: depth, visibility, current, and water temperature. Attach an anchor, an engine, a nameplate, structure, or a sonar still.
-
04
Trace the drift
Lift a historical fix, estimate how far the wreck may have moved and on which bearing, draw the search area, then log the discovery. Watch keeps the next dive window and a short field brief beside it.
On the phone
Quarry, dossier, and the drift trail.
