its hard man, the energy req looks like a huge task lol

I don't mean with the harpoon. I mean just sail toward shore while it follows the boat. Often it will swim into shallow waters where you can hop in and melee it.

I don't make the harpoon, but the abyssal razor is a very good mid-level knife. That and a fine wood bow were my only two weapons this playthrough until I got some silver to make a silver knife and Draugr Fang. It even works in the plains if you don't overextend.
