I bought a hunter 31, and I thought the mainsheet was supposed to be double ended and controllable from the helm station OR the coach roof. However, mine terminates at the boom and is only controllable from the coach roof. The owner's manual shows it as not double ended, like mine. Does anyone out there have one that's rigged with dual ended control of the mainsheet, and was it an after-purchase modification or did the factory make some of them like that? I'd really rather have control of main sheeting from the helm rather than having to climb back and forth repeatedly.
