Description: |
| "...a new and useful Improvement in an Apparatus for Indicating the Leeway Made by Ships and other Vessels... My invention relates to an improvement in the manner of attaching and combine the vane which passes through the water, with the rod which communicates with, or carries the pointer showing its position, above the deck or, inside the vessel, for the purpose of allowing the vane to be drawn up into the vessel when, passing over shoals or, from other causes, not requiring its use.". |
