The longer the better really. Nylon will snap back on parting and has on occasions killed people on decks of tugs. I have happily used 10mm climbing rope and floating rope to tow 5 mm ribs in a variety of conditions. Unless your rib is set up as a tow boat it is unlikely you will have dedicated rope. The rougher the conditions the longer the tow.

Suppose you could pass a second tow line over too to share the load.

10 or 12 mm braidline would be fine for general small boat towage and as was said earlier in the thread nylon even though it can stretch up to half before parting does have great shock loading propeties,and yes i have seen a couple of bad incidents where nylon has been used under load ,
worst was a smallish speedboat that was swamped the novice owner tied his nylon anchor line to a 4x4 hoping to drag it out of the water when the chrome bow fitting broke out and hit the owner in the face him nearly loosing the sight in one eye
just as a matter of intrest braid line of 12 mm has a breaking load somewhere around 2 tons on a decent length of line ,
as phil (chewy) said its sometimes the snatch loading on fittings that can fail as much as the rope.

pic of our Atlantic75 when we lent it to phil (Chewys ) station for a few weeks whilst their boat was in for a refit ,
and my own y boat sib towing back a broken down boat using 10mm braid .

dont forget that if towing a much heavier boat you will most likely need a bridle set up that can slide about from the transom otherwise you cannot get steerage proper unless you have a samson post set up infront of the propeller .
last pic my tow line and bridle set up for towing off the transom.

You'd never manage to get the ropes the same length to share the strain... would having two ropes double the risk on whipping back.......

Our Atlantic has towed a Tyne class lifeboat which is 47ft of steel and weighs 25 tonnes, Mart may be able to tell you the size of tow rope used on the Atlantics?
