Just look at a world map or a globe. Of course, most of it will be blue. It is honestly hard to picture the sheer size and volume of the world’s oceans. They are practically endless. It’s something you can only truly experience and understand when you sail long distances across them.
I’ve crossed the Atlantic, Pacific, and Indian, plus the Mediterranean, Aegean, and Caribbean. The Pacific, in particular, is so much bigger than you can imagine. I once spent days and days sailing that massive ocean—which is bigger than the landmass of all continents combined—with absolutely no terra firma in sight.
