I prefer to go for sailing and exploring new areas where I build outposts etc.
Then I build teleport there if place is nice or worthy then I sail back to my main land.

You only have to sail back if you are loaded with ores. Otherwise you can just tear down the ship, pick up the mats, go through portal and build it anew at your main base to go explore in other directions.
