The weak link MUST be placed at the tug end of the rope, otherwise it can't protect the tug in the event of fence strikes. We used to use a short length of 6mm rope as the weak link which was less risk of damaging the glider if it were to fail. However we have now moved from this method to the more precise Tost weak link with the calibrated dual links. One thing I would suggest is that the Tost link is attached so that if it fails the housing of the weak link stays at the tug end, which means less bits coming back towards the glider!

Subject: Re: [Aus-soaring] Practice hook up procedure My experience is a weak link at the tow plane end where it does not get damaged by wear (dragged on ground at landing) etc and if a light glider is used then maybe another weak link is clipped in to end of rope at glider end. I am not too keen on extra weight on the glider end of rope as could do damage to glider canopies. I believe it cut badly into rear of wing of glider and rope eventually broke near the tug. I am sure somebody will fill us all in eventually Ian M On 19 March 2012 12:36, <tom.wilk...@internode.on.net> wrote: Though I don't understand much about this specific incident, surely having the rope wrapped around the back of the wind would cause some of the load in the rope to be distributed into the wing itself? This would mean the section of rope between the wing and the hook would be under less load than the rest of the rope and therefor the weak link wouldn't break?
