We clearly need new events that would make our ship trips more entertaining.
And believe it or not, I have few ideas!

Animal attack!
This event would create a swarm of seahorses and fly fishes on trade lines.
The ships sail would keep hitting to the seahorses and flying ones would
constantly hit the fly fishes! After enough hits the mother of all seahorses
or the father of all fly fishes would come and eat your boat and you would
permanently lose it!

Bloody waters!
Bloody waters would be an event where numerous ships of pirates and vikings
would appear around the realm. They would attack all ships in sight. To give
some challenge to the event these npc ships would be untouchable by players
and they would be faster and have more firepower! The event would stop when
all player ships would have been sank and destroyed permanently!
