Depends on what you call a dingy.

For my small inflatable in calm water, I use Poly... easy to splice,
cheap, will last for years if you get it out of the sun after use.

For my tender (18' whaler)in rough water, I use 5/8" nylon with a VERY
long bridle (40') and another 60' of tow line. Great stretch for
rougher seas. I shorten it at the tender end if needed so that the long
bridle stays intact for stabilty and a more straight pull. (Tested to
22 kts in 3-5' seas, 17 kts in 5-7' seas) When pulling into port, we
do shorten it on the tow boat end and go down to towing on the non-slip
side cleat.

My neighbor calls a 31 jupiter his "dingy" He uses a 3/4" Multibraid
with a similar setup to my Whaler.

Funny thing.... the ONLY time I ever got the line caught up in the
wheels was when I was towing the little guy with the floating line.
(had to cut it loose in 1000+ ft of water... you tend to be VERY careful
with heavy diameter nylon...)

What is the best line for towing a dinghy?

I have seen somewhere on the net a multifilament polypropylene dinghy tow
rope that looks a lot like braided line but it is poly and floats. Assume
this would be good. But can't seem to find it. If I recall it was yellow
with a red thread,
