I'm glad you asked A Raingutter Regatta is a boat race using small hand-built boats with sails. The boats are placed in a raingutter and the competitors act as the wind source by blowing the boat from one end of the gutter to the other Here are some real life pictures of a Raingutter Regatta event.

The Campfire, a brand new fellowship, is holding it's first tournament, Raingutter Regatta #1. Since it's difficult to get us all together on such short notice (much less taking time to build all those little boats), we are simply including all BrainKing naval tactics games in our tournament. So if you like playing Battleboats, Dark Battle Boats, or Battle Boats Plus, please stop by The Campfire and sign up!
