If you use the RTTHH to secure a boat to say a swinging mooring it has been known to undo when there is a lot of movement (snatch in the line), much more so with modern braid on braid and double braid ropes than more traditional 3 plait or hawser laid ropes. The solutions are to ensure you have a long tail end after the half hitches and to tie some extra half hitches.

It is a sad fact that hundreds of experienced small boat Instructors have been brain washed into condemning the locking turn. The OXO and 0800 are OK for securing for a few minutes but they are not secure enough to trust your boat to, for long term and I have seen a yacht secured in this manor slip itself free. There are two reasons why the locking turn gained a poor reputation and they both occur when the person tying the cleat does it wrongly.
When tying to a standard T or TT shaped cleat, I recommend one or more round turns around the leg(s) followed by two (preferably more) fig 8s around the 2 horns of the cleat, followed by a locking turn on one of the horns. The locking turn is then gripping onto rope and not onto the metal cleat. Those that miss out the figures of 8s and put the locking turn straight onto the metal horn risk it tightening so much that it literally locks and they can not undo it.
The second problem with locking turns is when one boat ties to a cleat in the manor described above and then a second line is tied over the top. The force of the top line tightening can also cause the locking turn from the first line to lock too tight.
In summary a locking turn used correctly is not a problem and a far better way of tying up the boat than 0800 and OXO. The key points are
- Use 2 or more Figure of 8s before the locking turn.
- Dont tie a second line over a locking turn
Those that slander the locking turn have simply misunderstood how to use it correctly.
