Vince Cobbley and his son are as much self proclaimed "experts" as some others i know...problem is ive seen the other and i would trust my life there first!

I once watched vince do winch demonstration at i think it was Driffield and all of us (strangers) at the end closest were shocked by the techniques used. Mike

As stated above, you never load a shackle in a way which could potentially allow the pin to unscrew, so the shackle in the photo is the correct way round. (As stated above, if it was the other way round and was pulled along the strop under load, then the pin could unscrew).

If, for any reason, you have to use a shackle in a situation which load thepin on a 'running part' of the rigging, then you should wire the pin to ensure that it cannot turn (and you all carry a length of wire for this purpose with your recovery gear, don't you Wink ).

Of course, in 99 out of 100 situations you'll be fine anyway, but the 100th - when the shackle comes apart and bits of the rig take off at a couple of hundred MPH - is the one you plan for.

Thats why everyone should be using 4 part shackles, screw and pin are rarely used commercially anymore. The big difference is winching is not classed as lifting and therefore people tend to sail closer to the wind with the rigging gear. A bow shackle is designed yo take some of the load on the bow shoulders.

Never done any winching course myself but would recommend people to do so when first starting out.

For the photo shown it does not matter to me. In lifting situations the strap is always in the bow if attached to a pulley. A bow is useful in that you get two straps inside the bow, such as the ends of a tree trunk protector. in this case the snatch block would be the pin side.
