yes the 5.2 in a bit weird with the loose main halyard, once halyard slug on the cable length has locked into it's fork? at the top of the mast the rope section just hangs free
a couple of feet above the tramp on my mast there is a small hook on a bungy that keeps the halyard from swinging around in the wind. the excess halyard i coil and stick down the tramp sleeve for the midtramp bare. but that sleeve won't really hold the jib halyard too so it goes into a mesh bag i bougth at a $1 shop and tie onto the mast base
a good sailing shop should have some monel rivets for your mast base
check very carefully around the bottom back of the dagger well for your hull leak. you may be able to fix it yourself once you find it
