Ace Sailmakers: Jordan Series Drogue Pricing and Order Form

WHAT IS IT?

The Jordan Series Drogue is a safety device deployed from the stern of the vessel.

It consists of a bridle, a leader and a tapered line with from 100 to 200, 5 inch diameter cones attached. A 15 to 25 lb. chain is then attached to the end. The number of cones and rope diameter is adjusted for the displacement of the vessel.

The figure below shows a computer simulation of a 55 ft yacht in the trough of a 45 ft breaking wave in the 1998 Sydney Hobart Race. A series drogue is deployed.

Ace Sailmakers makes the series drogue or has it available in kit form.

*Design information for series drogues suited to different size boats is provided in Coast Guard Report CG-D-20-87, which may be obtained from the National Technical Information Service, Springfield, VA 22161.
