The best way to increase your line capacity per drum size is with a HSC rope & chain kit. HMPE Hi Spec Rope is the same stuff used in 4×4 winches. It is stronger than steel per diameter and goes a long way to adding extra length per given drum size. All HMPE rope kits come with a double braid nylon tops shot for stretch and abrasion resistance against the sea floor. The top shot can be changed with wear if desired.
