The Searunner Trimarans are a series of wooden, home-built, multihull sailing vessels designed by John Marples and Jim Brown. Searunner Trimarans were designed in five hull sizes: 25, 31, 34, 37 and 40 feet. Intended for circumnavigation, these wooden-hull boats attract the craftsman builder and adventurer. Although Jim Brown has retired, John Marples continues to offer assistance to current Searunner builders and sailors. As of 2010, plans can still be purchased through Duck Flat Wooden Boats in South Australia, with many older Searunner Trimarans are available for sale across the world.
