I've been assuming a "sector" is one stone plate on the table-map. There are 16 sectors currently available (3 in Emerald Isles, 8 in the Fallen Heights inner ring, and 5 in the Red Cliffs area). If "exploring" a sector means adding a plate to the table-map, then that (unachievable) achievement implies a very ambitious road-map. Also, I noticed one of the ready-made images on the store page shows a character at the helm in front of a larger table-map.

I have a silly goal of "someday" testing this by sailing constantly around and around and around while I putter about my IRL home doing chores. If I do that, I'll report my findings here.

Heh, I am actually working on something similar right now. I've started a new world with my existing character, since I learned I still had build pieces to unlock, and have been speeding through the sectors to reach the Red Cliffs area, and once I have nothing left to learn I intend to keep sailing through world after world.

Clever! Probably the only way to get that achievement, if at all.
