We use a Fortress FX 55 which hangs off the pushpit on a specially designed bracket. We chose this as its light we have the option to use 10 m of 10 mm chain and the line is 100 m x 24 mm multiplait. This doubles up as our second anchor. (We have a third but it rarely see's the light of day.) Four years in the Med. and we have had to put it out half a dozen times due to the wind. Now that we are in Greece we use it more than ever as a kedge, in the small harbour's.
