Thanks for the amazing fast response. I just got my boat from storage (parent's driveway) so that I and the kids can start work on some projects. I'll check how much head room the mainsail has and if possible, try Sumner's gooseneck lift.
I don't expect to get standing room, so if sitting is comfortable and movign around is possible, then that is the goal. I'd go for a short length bimini since I know we will have to stand to get from cockpit down the companion stairs. Or do some serious gyrations and belly crawling that the Admiral has no interest in doing.
