Hi
We have a similar anchor arrangement, plus a small spare we use for beaching. Unless you make a bow system to hold a plough, we're all sort of stuck on using the flatpack type. (plans are already underway...) I quite like the standard kit. Seems to work pretty well.
As fore usefull mooring ropes, I find a 6mm line fixed to the bow roller (n stored in the locker when not being used) that is just short of the length of the boat very useful. (any longer, if it sneaks out for a swim it may decide to copulate with the prop at any moment)
If I'm coming alongside single handed, I simply run the line round the outside of the shrouds and clip it into the jib sheet cam cleat. A 3m looped/eyed warp on the back is the other, figure of 8ed onto the rear cleat.(leaves room to cleat more strings on later) It means you can jump ashore with the 2 lines in hand quickly n easily if no one ashore to catch a line (which too is easily to hand from the helm.)
This set up has made me feel very smug n smarmy when coming into Poole quay (a very frequent waiting place for us) as I make the process look effortless (little do they know I'm an utter newbie at this!)
Once held, I use an 8mm 20m rope to go from the bow to shore, sprung back to the jib traveller (it's great coz you can move it around to fine tune later) off to the shore and back to the stern somewhere. As the cleats are all so pathetic you can't use man sized ropes! the original then can be left as a safety, plus it makes casting off pretty easy. Can't wait to get some proper cleats on.
If you're on a wall with dozens of powered idiots blasting past causing major wakes, a couple of lengths of shock cord (10mm) can act as very effective snatch absorbers. I tie them from the guard rail to nearest terra firma. Beware though as they do sort of like to untie themselves.
