Antique Nautical Ship's ocean measurement device with wood case. I believe it is a form of combination AQUAKNOT Ocean Speed / Current & Compass tool. I am unsure of its exact purpose as the information sheet stapled to the inside has faded away but one of the metal fins is stamped "RAGNAR EKBERG". Based on the construction of the wood and case markings, I believe this tool dates somewhere between the 1940s-1960s with it most likely dating to the late 50s or early 60s.

The case is marked "Antarctica" and underneath that is the remains of a customs sticker. The case also has a plastic label attached to the front that reads "CAUTION: Wash thoroughly with fresh water after each use." As the box would imply, I believe this was used in an Antarctic expedition. Being used on the deck of a ship in harsh conditions traversing the Antarctic would also explain the fading to the inside paper label.

To operate it, I believe the Aquaknot is attached to the vessel and dropped into the water. The drag created moves the propeller and turns the indicator depending on the boat's speed. The upper Indicator shows speeds up to 10 knots, I am unsure of what the larger lower indicator measures.

This tool seems to be constructed of mainly stainless steel and looks to have minor staining / corrosion from salt water use. I have included a picture of it assembled but it breaks down to fit inside the case. A very unique piece for any nautical collector, avid sailor or for your man cave display.

$425 Cash. Please reply by email to this listing if interested. Thanks for looking!
