This one @Levis.Also I tried a tailor fetch quest for the perk. He wanted 4505 cotton in 5 weeks. Now here I am paddling along in a 6th rate frigate. Visited 2 islands and bought the biggest ships they had, a light pinnace and a merchant pinnace, and filled all 3 ships and still came up well short. So I dropped the cargo off with the tailor and made another run for the rest. Missed the deadline by 4 days, but the fetch quest stayed in my quest book and the tailor would not acknowledge the 2nd load at all but only had his standard dialog.
So I deleted all saves from that failure and am now on a quest to buy lots of giant ships for the next one. Level 65 btw.
