scullduggery

Less-than-honorable behavior regarding the paddling of a boat.

Races of canoes or rowboats are notorious for scullduggery; one of the most common subterfuges is to conceal an outboard motor on the boat to make it go faster. Be sure to bring along a noisy boombox to help cover the tell-tale "putt-putt" sounds, though, unless you use a souped-up electric trolling-motor that runs virtually silent.
