My 18sf came with hydraulic steering, which I upgraded the helm pump (tilt!) and the hoses on when I did my refit last year.
I ran the hoses through the "conduit" that already exists below deck on the stbd side.
Its just a slot through and along the stringer, not really in the bilge.

I bought the premium teleflex hoses, and secured them as best I could, where I could.
Not really concerned about chafe.
