what I have is a tow rope for my tube, it ends in a loop, where i want
to attach the triangular rope that comes from the boat.

I could just connect the loops but (i got the cheapy rope that rubs
through the fibres where they connect real quick and i dont want to
keep snipping the rope.

On my tube is a nice connector piece ... hard to describe .. its sort
of a disc with a hole ... you push the loop through the hole and wrap
it around two "hooks" on the disc ...

I am thinking that would be a nice way to connect the rope to rope too
.... any idea where i can get that or how to connect my ropes so they
dont fray ?
