The boat does best on 3/8 rode(it does not screech 1/2 right), 5:1
to 10:1 scope, 1/4 inch chain for your area (20+- feet), PS rates New
England Best 3 strand, and for chafe a split hose or one of the
"guards" you need to be able to reposition, I use chapmans for a source
on this one. My note also, if you need a second anchor set a second
anchor, the more parts in line the more places to fail.
For dock lines, which really depend on the dock, a 3 or 4 point with
half inch line is fine with a good chaff guards.
