"Rope" - any educated guesses as to how long the rope is, i.e., inches, feet, tens of feet, hundreds of feet etc.?

Yes thats in the wiki, also it was used by the coastguards and RNLI in the UK to get lines to vessels in trouble.

Rope can be presserved for a long time in sea water as usually it was covered in tar and other oils to preserve it at sea.

does anyone know what a rocket line looks like  ?

Here's an example from WWII.  Note the smaller line size - it has to travel behind the rocket; of course a larger line could be manipulated between shore and ship once the smaller line was established. 

Here are examples of some rockets used with such devices.

Flotation line is mentioned in some texts on these - an obvious advantage would be to avoid entanglement on reef structure.

re: the rope or line in the ROV video. How about this stuff? It is pot line, used to attach float to fishing pots, about 1/2 inch diameter.

It's called a "messenger line," a light line that is then used to pull out a heavier line. It may be necessary when passing a very heavy line to do this twice, a light messenger pulling out a stronger messenger which is then use to pull out the strong line.

Thats right the UK coast guards or RNLI crews fire a light line to the target (ship) who then secure the line to a heavier line for the rescuers to pull it back and carry on with their rescue.

Richie,

Checking the Wiki the line was fired to the Norwich City Crew 1 1/2 miles south of the wreck.  The prevailing currents would take a line left in the sea further south of the island.
