How are rogue waves different from other waves?

Rogues, called ‘extreme storm waves’ by scientists, are those waves which are greater than twice the size of surrounding waves, are very unpredictable, and often come unexpectedly from directions other than prevailing wind and waves.

What is the main reason that little is known about rogue waves?

Rogue waves seem not to have a single distinct cause, but occur where physical factors such as high winds and strong currents cause waves to merge to create a single exceptionally large wave. Rogue waves can occur in media other than water.

What wave height is dangerous?

For example, using the minimum 30 percent wave height to boat length, if your boat is 40 feet long, then the wave-height danger zone starts at waves 12 feet high (40 x 30). A wave 12 feet high could knock down a boat 40 feet long if the boat is caught somewhere near beam onto the wave as it breaks.
