Ken, You bring up some excellent points concerning the size of your new boat. After doing much research into series drogues and para anchors, I elected to go with the Jordan Series Drogue on Flat Earth. During the design process, I was fortunate to be able to talk to Don Jordan himself who is now over 90 years old. Since my boat is an 80,000 pound boat, I thought that my series drogue would be similar to what was posted on the web site for a 70,000 lb boat (which was the largest boat they listed). Not so! Don noted that the design for those boats was actually for a 70,000 lb sail boat and that a larger drogue would be needed for a flat stern power boat. My drogue ended up being 490' long as opposed to 370' for the 70,000 lb sailboat. I can't imaging how long and big a series drogue for your 200,000 lb boat would be. I think you'll have similar problems getting a properly sized para anchor for your boat that will not rip apart under the stresses. Posted below are some of the web sites that I used during my research including the site for Ace Sail Makers who manufactured my drogue. Mike Maurice has also done extensive research on the subject. It was his knowledgeable posts several years ago that first got me to look at the Jordan Series Drogue. Please note that the Galerider Drogue and the Series drogues are two very different animals used under different circumstances. I am also considering adding a towed drogue such as the Galerider to my safety equipment. http://www.jordanseriesdrogue.com/D_4_m1.htm http://www.jordanseriesdrogue.com/ http://www.dddb.com/links.html http://www.landfallnavigation.com/galerider.html Phil Eslinger Flat Earth N50 Ko Olina, Hi
