What sort of recover rope do you want? Just a tow rope, or a kinetic rope/strap?
For a tow rope yes marine 3 strand polyester or nylon 24mm diameter minimum. For a kinetic recovery rope/strap lots of companies offering double braid style ropes now days, (the new KERR) Terrafirma seem to have good kit a good prices, Ironman do one also, ARB do straps, but you pay for their name.
