Why Do People Spell It “Bouy”?
Several reasons explain this common spelling error.
1. Letter reversal
The sequence uo isn’t very common in English.

Fast typing often causes adjacent letters to switch places.
This creates many common errors like:

The pronunciation gives very little clue about the spelling.
Since people hear:

they often guess the spelling incorrectly.
