One of the problems with a CC can be the lack of shade in the cockpit. You can't run a joining cover from the back of the dodger to the bimini on the stern rail because the mainsheet runs to the traveller from the end of the boom halfway along the aft deck area. I was thinking it would be possible to install a frame just forward of the traveller so that I could run such a cover over the cockpit whilst underway. It would need an opening at the helm where the helmsman's head would stick out (my head comes to just below the boom when sail is down, traveller is centred and mainsheet cinched down). I have seen boats in colder regions do such a thing (eg. Drake on Paragon).
Has anyone ever seen a centre cockpit boat with such a setup? Is this stupid?
The mainsheet and boom would need not to interfere with the frame when running.
It could serve as a boom crutch type thing (though I'm not sure there's any advantage in that to a topping lift, which I have).
It could be ugly if done wrong but could be very useful and may look okay if done right.
