The 1D35 is a strict one-design class featuring a lightweight, planing hull. Designed by the design team of Bruce Nelson and Bruce Marek, the 1D35 is raced with different spinnakers for different settings: a large conventional spinnaker for buoy racing and an asymmetrical spinnaker for open water. The boat features an innovative carbon-fiber mast and a 100% jib and is easily trailered and often dry-sailed. An adjustable headstay rig with no backstay offers direct yet efficient control. The 1D35 is similar to, and perhaps eclipsed by, the newer Farr 36 one design, but continues to be actively raced, particularly in the Bay Area.
