Boardsailing is formed from "board" (from Old English *bord*, meaning a flat piece of wood or plank) and "sailing" (from Old English *segelan*, meaning to sail). The word refers to the activity of sailing on a board, typically a surfboard or windsurfing board.
Think of a 'board' (a flat piece of wood) that you use for 'sailing' — this helps you remember that boardsailing is the activity of sailing on a board.
