Product Details:

This particular unit seems to be missing several minor parts but generally looks operational. It is the subject picture.

Dead reckoning tables (DRT) were used to physically draw coordinates of a ship as it followed a course at sea. Most often to double back to an exact location and retrieve a man overboard. Large graph paper was placed under the plotter and the mechanized assembly in the bottom compartment manipulated the X and Y axis accordingly.

Wood cabinet and frame, lid with glass panels. Shows the wear of many years on a battleship. Overall dimensions 39" x 53" x 14". Usually the Navy painters got carried away and painted the bottom portion of the cabinet.

We have a variety of DRTs available ranging in price from $300 for a bare case with no lid and various drive parts to $4000 for a complete and rebuilt unit ready for the high seas. Dead reckoning equipment to drive the plotters also available from SSON. We are not experts with this equipment as it was acquired when we purchased Compass Technical of Patterson, NJ. We continue to catalog this antique material week by week, year by year.

Shipping: The DRT is large and heavy. If shipped motor freight we will cover it in Styrofoam, then corrugated and band it to a skid for $50. Figure $100-$300 or so for motor freight, depending on the ship to address.
