Like that

You will be pleased to know that my knotting skills came into practise a few moments ago...the two ends of the draw string on a sock bag had come undone. At first I tried the reef - two ends of the same rope = same diameter - to no avail. Same result with the sheet bend. Then set about making the rabbit piss round the back of the tree and there are two neat bowlines holding it together.....

There's another way to tie it, much simpler than the animation (though you may have trouble following it by text):

Take the line, and twist it into a loop (for simplicity, let's leave the loop below the two horizontal running lines at the top.) Twist the loop again, giving you a doubled twist at the intersection. Now for the tricky (to describe) part: Open the center section of the doubled twist, creating the two running lines, an intersection, an opening, the second intersection, and the remainder of the loop. While holding the bottom twist, pass the bottom of the loop up behind the whole mess, over the top, and feed it through the eye. Pull enough of the loop through to the size you want, and draw everything up.

To untie after the knot's been loaded, work the "ears" down the running lines a bit, then pull the loop back through.

Yes, first by me, in the flow of the thread.

What's your problem?

I used overhand stoppers on mine - the knot is bigger so doesn't pull through the hole & / or undo so easily.

Only time I use them "in anger" is on a dinghy sheet, and then with a foot or so of rope "free side" of the knot. The number of those knots I've seen doing what they were designed to do hard in a block with the crew scratcing at the 0.5" tail with their fingernails to retrieve the rope.....

The solutions are to ensure you have a long tail end after the half hitches and to tie some extra half hitches.
Or you could just use a know designed for that sort of repeated snatch loading - something like the Fisherman's/Anchor Bend. (In theory harder to release than a RTTHH but I've never found a problem).

Actually, I did, last year: A buddy's engine died, and the RIB was heading onto the beach. I got his bow line and tied it off to my A-Frame, using a double anchor bend (two circles and tuck the end back through.) Pulled him the several hundred yards upriver to the ramp, and the bend had tightened so much that I couldn't get anything loose. Ended up cutting the line, as current was getting to be a problem.

Looking back, there wasn't really much else I could have done other than perhaps using a slipped bend (pull a bight through rather than the entire end), but speed and security were more important at the time.

I agree with Jyasaki the fisherman's is very hard to undo after it has been under load, and impossible to undo while it is under load
