Abstract: A support apparatus for use on a watercraft to hold several trolling devices such as outriggers, downriggers, and fishing rods includes oppositely disposed base members and a bridge structure including opposite vertical portions each attached to and extending upward from a corresponding one of the base members, and a horizontally extending portion integral with upper end zones of the vertical portions. The opposite base members removably mount to the watercraft to support the bridge structure above the watercraft's stern. Mounting structures are provided on the base members and bridge structure for holding the trolling devices in operative positions thereon.
