Jim Brown is a multihull sailboat designer who collaborates with John Marples.
[1] The pair are responsible for the Constant camber, Seaclipper and Searunner[1] series of trimarans.
Early in his career, Jim Brown was inspired by Arthur Piver.
[1] Jim Brown stayed with Piver's narrow-waisted hulls while introducing the centerboard, center cockpit, and cutter rig.
While poor payload capacity and hobby-horsing are owner complaints with the 31 and 37, his 40-footer gets high marks.
