Depth adjustment for racing marks

Post by ianrmcdonald » Thu Nov 30, 2017 8:35 am

Now its cold, it would be nice find a simpler method of adjusting the length of the anchor line on our racing marks so that its kept out of the way. We have significant variation in depth over our racing area. Currently using karabiner and loops which is simple but fiddly .

Your suggestions ?

Hi Ian, If you are able to come to Bournville on Sunday for a sail i will explain and show you how this is done. It’s simple and not fiddly.

We have some marks for use in varying depth and deeper water. The mark has a hollow tube through the center (a cut off golf club works). Then we have an anchor line that passes up through the tube to a spool of line on a wooden shaft that plugs into the top of the tube. Drop the anchor line to the bottom, then plug the shaft into the tube - locking the line at the correct depth. To retrieve the mark, pull the spool and wind up the line and plug back into the mark for storage. And you hands don't get wet.

At Datchet we sail on a reservoir which has a sloping base, we decided that we need to adjust the line to suit when the water is inor out or adjust position of buoys to suit, so our lines are 24 meters long secured to a sinker which has a toggle on a 300mm spliced line secured to it. At intervals on the line we have spliced hoops just put the toggle through hoop to reduce line. In addition we use a block on a 300mm spliced line at each buoy and use a counter balance weight (old window sash) to take up the slack and keep the buoy line as straight as possible

Simple solutions to varying depth of water it suits what we need and the water depth at Datchet.

We have for many years used a simple slider system in that the anchor line goes into a loop on the bouy and is then attached to a piece of pipe which has the anchor line running through it so that the pipe goes up and down the anchor line as the water rises and falls keeping a constant tension on the bouy
