Tie: Captured Overhand Cuff

Based on this tutorial.

This is a cuff that will not collapse or loosen regardless of which direction tension is applied. It involves an overhand knot that is "catpured" from both sides, keeping it stable.

1. Tie the first wrist with doubled-rope.
2. Bring the rope towards the second wrist.
3. Make an overhand knot with the 2 strands. This knot will be the inner-most point of the second cuff. This controls how closely the wrists will be tied. I will call the space before the overhand knot, the "overhand space". It's not a problem if this overhand knot collapses into a half-hitch.
4. Wrap the wrist with the doubled rope and bring it through the overhand space. Pull it to close the cuff to the desired size.
5. Wrap the wrist one more time and it bring the rope back to the overhand knot again. I will assume the wrapping is going downwards on the wrist.
6. Any further wraps should be in the same direction. Only the first wrap should go through the overhand space, otherwise it will get quite crowded.
7. Bring the rope upwards, over all of the wraps, then downwards inside the wraps and pull back towards the first wrist. Ensure that all of the wraps are the same size.
8. Bring the rope to the other side of the overhand knot and make a half-hitch around the 2 strands of rope there and tighten it against the overhand knot (there is 1 wrap between it and the overhand).

Tie: Shinju chest harness

Based on this tutorial

1. Complete a lark's head and half-hitch around the chest. This gives 2x2 wraps above the chest. Ensure the half-hitch is adjusted to point down from the knot.
2. Leaving a little slack, wrap once around the chest under the breasts all the way back to the centre of the back.
3. Pull the rope through the start of the wrap and adjust the slack so that the upper and lower wraps are connected by a short vertical stem.
4. From here, it's essentially another lark's head and half-hitch but with previous step instead of a lark's head. The rope should be leaving the half-hitch going upwards.
5. Wrap once around the stem and take the rope under the top set of wraps and over the right shoulder. This reinforces the stem and stops it from disappearing when the rope is under tension.
6. At the front, take the rope from the shoulder (on the left now) and bring it diagonally down and across the chest to the bottom set of wraps.
7. Slightly past the center (to the right as you face it), bring the rope over the bottom set of wraps then back up between the wraps and the chest, coming out to the left of the incoming diagonal.
8. Bring the rope to the opposite shoulder going under the top wraps. Be careful that tension on the rope does't cause the bottom wraps to bunch up. If there is a lot of space between upper and lower wraps, you might want to wrap the earlier diagonal once to help prevent that space from closing.
9. Coming to the back, take the rope over the shoulder and down under the top set of wraps
10. Reverse direction by pulling the rope over to the other side and lock it off with a half-hitch (or two) on the upper wraps.

Knot: Midshipman's Hitch

Based on this tutorial but mostly this animated knot

1. Cross the tail over the standing end. This is "the crossing".
2. Pass the tail around the standing end and up through the bight so that it circles the rope above the crossing.
3. Pass the tail through the bight one more time. This time it should wrap above the crossing but below the previous one. Now we have an awning hitch. This can take load.
4. Put some load on the awning hitch
5. Crossing the rope in the same direction as before, tie a half hitch below the crossing.

Adjusting

This can be adjusted by holding the knot and pulling the section of the rope that was wrapped through the knot from either side.

Other notes

If tying with very slippy rope, 3 circles may be required.

Knot: Lark's head and half-hitch

 Based on this tutorial.

1. Wrap the column once and pass the entire tail of the rope through the bight at the head to form a lark's head around the column.
2. Reverse direction and wrap the column one more time below the previous wrap.
3. Pass the entire tail through the newly formed double-bight. The tail should pass upwards, behind the 2 lower strands.
4. Reverse direction to bring the tail over to the opposite side of the lark's head.
5. Pull the tail upward to form a bight with the rest of the tail falling down across the wrap.
6. Pull the rest of the tail upwards, behind wrap and through the bight to form a half-hitch.
7. Tighten the half-hitch.

Orientation

You can adjust the half-hitch so that the tail of the rope is coming out of the knot upwards or downwards, as you like.

Tie: Wrists behind neck

Based on this tutorial.

1. Tie the wrists using e.g. Lark's Head Double Column Cuffs.
2. Bring the wrists over the head and pull down so that the tail of the rope is going down the centre of the back.
3. Take the tail of the rope off to one side and wrap around the front and back to the back.
4. Pull the tail between the back and the vertical rope and then down over the start of the wrap to form a cross.
5. Adjust the rope so that the cross is centered and the rope is tensioned as desired.
6. Wrap back again in the opposite direction (under or over the existing wrap).
7. Bring the tail through the bight formed in step 6.
8. Tie it off in a half-hitch on the opposite side.
9. Optionally use the spare rope to pull the wrists tighter.

If the wrists are not pulled far enough back, it is quite possible that the bottom can slip their head through an arm and get their elbows down. Pulling them back tightly may make this tie intolerable. Instead you can use more rope on the arms to make it impossible for the head to pass through.

Tie: Lark's Head Double Column Cuffs

Based on this tutorial

1. Form a lark's head and place it around both columns with the lark's head in the middle of the two columns.
2. Add 2 more wraps going up the columns so that there are 6 strands of rope around the columns. You now have 6 strands that go above and below the columns.
3. Pass the tail of the rope downwards through the bight formed by the lark's head 
4. Pass the tail of the rope under the lower strands of rope (going upwards relative to the columns)  then wrap it back over the top strands (going downwards).
5. Pass the tail of the rope downwards through the lark's head bight. This captures the entire upper and lower set of strands.
6. Adjust the tension to bring the columns together as much as desired.
7. Holding the knot under tension (if possible), open a bight downwards and on the opposite side from the lark's head then pass the tail over the top of the strands.
8. Pass the tail back under the upper strands to wrap them and pull them through the bight to form a half-hitch.
9. Readjust the tightness if needed.

Knot: Somerville Bow Line

1. Wrap the rope at least twice around the column (so 4 strands everywhere).
2. Leave about 10cm loose at the head.
3. Bring the tail over the top of the 4 strands.
4. Make a loop in the tail. The loop should pass under the tail. So now, the 4 strands and the loop are all laying under a section of the tail.
5. Take the head up through the loop and back across that section of the tail and feed it under the 4 strands coming up through the loop again. Probably easiest to reach 2 fingers through the loop and under the strands to grab it.
6. Tighten the loop.

The Somerville bowline is a secure knot but it is very hard to release it if the tail if under tension. You first have to ease the tension but that may be difficult. If needed, consider the following modification.

Slipped version

• At step 2: leave about 20cm at the head, instead of 10cm
• At step 5: above when feeding the head through the loop, fold it over so that you feed 4 strands through the loop and tighten on that. The head never goes through loop.
• When you need to release, pull the head. This will pull those 4 strands back out of the loop and the know will release.

Other notes

After tying, the head and tail will point in a opposite directions, perpendicular to the 4 strands. When you wrap the strands around the column, if you choose to put the head above the tail then at the end, the head will point down and the tail will point up and vice-versa.

The loop in step 4 can pass over the tail if you really want but then in step 5, you have to bring the head under the strands that are around the column but then into the loop from the top. Otherwise the loop will not form a knot. It's easier to form the loop this way but it's definitely harder to feed the head into it. Maybe it's useful sometimes...

Different technique is in this tutorial.
