Counter-Canoe Chess

Two players sit in a canoe, facing opposite directions. Each gets a paddle of their choice. Between them, a chessboard is attached to the boat at lap level. It is magnetic, to prevent piece scattering. The canoe is put in a pool, equidistant from two lines.

A player wins by either crossing the line they face towards or by winning the chess game. Paddling is not allowed when it is your move.

Two lines are also drawn to the sides of the canoe. If the canoe crosses either of them, the person currently paddling loses.

"Touching the pool wall" can be substituted for "crossing the line" if the game is not part of a tournament and so the regulations need not be followed strictly.

To prevent the player better at memorizing from winning, Fisher's Random Chess can be played instead of regular chess.
