One of the problems of buying a boat in the fall is that you don’t get to play with your new toy until spring. \u00a0We are left with thoughts and plans, but not a lot of practical hands-on work to do. \u00a0But we did find a winter project to attack, a Series Drogue of Donald Jordan’s design. \u00a0Kinship was sold without a drogue, though it is fitted for one, but the last owner is now using it on his new boat.\u00a0\"2014-12-07<\/a><\/p>\n

There are massive chainplates on the stern to take the bridle line on the drogue. \u00a0 The series drogue is designed as a way to survive breaking waves in a storm. \u00a0In large seas, a boat can race down the face of a wave and end up slewed to one side in the trough. This allows a wave to break over the boat, potentially rolling the boat. \u00a0Many boats have lost their rigs in these accidents and some have sunk.<\/p>\n

 <\/p>\n

A drogue works by slowing the boat as it rides down the wave and in the process keeps the bow pointing in the right direction. \u00a0A breaking wave will poop the cockpit but will not roll the boat. \u00a0 There are a few different designs of drogues, most have a single large cone or parachute to provide the drag. \u00a0This type of design can break the surface of the water between waves and can lead to large snatch loads as the drogue re-enters the water. \u00a0A series drogue has many small cones on a long line to provide the required drag. \u00a0This ensures that even if the line is exposed in a trough, most of the cones are still providing drag and there are no snatch loads.<\/p>\n

For Kinship we need 124 cones and about 300ft\/100M of line. \u00a0We bought a kit with the cones from Sailrite and we picked up the line from our local marne store, \u00a0The Chandlery<\/a>. The first job was to cut the webbing tapes, 124 cones * 3 tapes was a lot of time spent at the stove using the hood to get ride of the fumes from the hot knife.<\/p>\n

\"2014-12-19<\/a><\/p>\n

That job done, the next stage is to build the cones, the 3 tapes are basted together with tape and then sewn. \u00a0We normally do a big jigsaw over the Christmas holidays, if you come over for dinner, you have to add some pieces to the puzzle to earn your food. \u00a0This year the drogue project replaced the jigsaw, Kathleen’s sister Angela did a great job an assembled about half the cones for us, thanks \u00a0Angela! \u00a0The next stage is sewing the tapes to the cones and then closing the cone.<\/p>\n

\"2014-12-31<\/a><\/p>\n

Kathleen used a section of pipe to store the cones as she built them. \u00a0The line is then passed through the pipe to make installing the cones easy.<\/p>\n

As Kathleen made the cones, I built the lines. \u00a0Using 3\/4 inch line, I spliced the two bridle lines and the first 140 ft section of line. \u00a0The series drogue is only used to reduce danger at sea, this focused my mind on the quality of my splices and I discarded the first 2 that I did. \u00a0I used a both my Toss wand and Selma fids to make the splices. the wand to but the cover in the core and the fid to put the core in the cover. \u00a0This allowed very consistent splices with no loose cover strands.<\/p>\n

I made the loops big enough to allow the lines to be joined using a cow hitch.<\/p>\n

\"2014-12-31<\/a> \"2014-12-31<\/a><\/p>\n

Once we had the lines made, we started the process of putting the cones on to the line.<\/p>\n

\"2015-01-02<\/a><\/p>\n

\"2015-01-02<\/a> \u00a0Adding the cones one at a time is a simple but slow process, the pipe stores the cones, the line, marked at 20 inch intervals with a 16 inch mark for each cone. \u00a0We have completed the first line, we are waiting for the small second line to come in, more on this project later.<\/p>\n","protected":false},"excerpt":{"rendered":"
