Jim Brown (multihull designer)

Jim Brown is a multihull sailboat designer who collaborates with John Marples.

The pair are responsible for the Constant camber, Seaclipper and Searunner series of trimarans.

Early in his career, Jim Brown was inspired by Arthur Piver. Jim is now retired.

Jim Brown stayed with Piver's narrow-waisted hulls while introducing the centerboard, center cockpit, and cutter rig. Of the 47 multihulls we spoke outside U.S. waters, 13 were Brown designs. While poor payload capacity and hobby-horsing are owner complaints with the 31 and 37, his 40-footer gets high marks. The Searunner's safety record is outstanding. Its divided accommodation provides the best ventilation of any boat in the tropics.
