I learnt a new way of making an outhaul safety the other day which I really love. See the below picture….

The clever thing about this is that the splice can be opened up (not completely taken apart because of the whipping) and then the knot slid through and the splice tightened. This allows you to put the main on the boom and put the outhaul on the clew ring and then put the outhaul safety through the clew ring. This means that the outhaul or the shackle could fail and you would have the outhaul safety as a back up allowing you to continue to race (with the main in the downwind position) until you sort out an alternative outhaul.
