The following is an encore presentation of everything everywhere daily.

Navigation on the open ocean is extremely difficult.

It's a skill that takes years to master.

Even with years of skill, an experienced mariner was still able to ground their ship on an unseen reef, underwater rocks, or a sandbar, because they didn't know their precise location. The main problem, which was

European navigators weren't so lucky.

They had much larger ships that sat much lower in the water.

If there was an underwater hazard such as a rock or a reef and they were unknowingly to hit it,

the results could be devastating. In fact, this happened far more often than most people realized.
