This device appears mounted across the cockpit in the newer and larger (than 26ft) boats, in some models the arch is made of fiberglass. A traveler is mounted atop and the mainsheet tied to it. http://www.yachtworld.com/boats/2006/Hunter-36-2894009/Norfolk/VA/United-States#.WxIvySBlDa8. It opens space in the cockpit since it can eliminate the mainsheet attachment on the floor in front of the pedestal H260. I wonder if such structure exist/can be adapted to the H260?
