Hi southface,
Keel is cast lead and has stainless bolts so I don't worry about that (I think all firts has that...). It is true about the cockpit entering but I really like that the traveler is on the back and also more important for me, that the boom is mounted ti the sheet at the back of the boom. I broke the boom on the bavaria 46 at accidental gybe in the med and I am certain that this happened since boom was mounted almost at the halfway (this is just from my bad experience and probably is not a general rule).
Maybe, when I am on the anchorage for more days, I just remove the wheel and put it away and whilst on the passage, autopilot will do his job... till it breaks
