been using a thicker 50' poly rope for deep water anchoring.
also like white or yellow because they are easier to see.
ive found them easier to use because they are cheap, handle easier, float & dont twist as often as nylon ropes or cords. The longer the rope & smaller the diameter, the harder its going to handle, & untangle but easier it will be to store. the best solution i heard of is to make quick connects that will join two 25' peaces together n carry them both.
combining two ropes, two retractable dog leashes or a rope to the end of a retractable dog leash will. this way your always ready for deep or shallow water.
25' plus ropes are going to tangle. to minimize, coil them properly on the retrieve.
here R just a few methods used:
winding them usually twist them n causes them to kink up then tangle. i dont recommend using a cord reel. i tried it a few times but didnt like it at all.
just methodically shove it into a mesh bag so it will also dry before re-stowing.
also best to untwist them when u can. for creeks n rivers, a drag chain, closed up claw anchor or dumbbell work fine as does a stake out pole & brush grabber. less than 20' i will also recommend a retractable dog leash on the other end of your anchor for fast-n-easy deployment/retrieval.
