gaffle (plural gaffles)

- Gaffling is a planning technique for orienteering relay courses whereby individual routes are planned so as to vary slightly and to make following difficult. This means that the competition depends more on navigational skills rather than just physical ability. See British Orienteering Federation's Event Guideline F for Relay Events, Section 3.
