I think the hurtigruten ships don't need a pilot to any ports on there homeroute along the norwegian coast. Also not for Trondheim. I never saw a pilot going on board either. Would be a little dificult with all the 34 ports in 11 days, hehe.

Edit: And I think, when a captain visits a port about 60 times a year it's not needed anymore. I know that the MS Nordnorge had pilots on her route in Chile, Argentina and Antarctica for sure. But not in her "norwegian homeports".
