My wife and I are thinking of upgrading from a Mac 25 to a Catalina 25. We looked at one yesterday in our price range and were left with a few questions.One of the 4 bolts that holds the swing keel pivot bolt in is missing. It looks to have fallen out (vibration?). There is no sign of any damage around the swing keel. Is this likley to have caused any damage by being missing and is it reasonably straightforward to replace?This boat has the taller mast option. To a MAcGregor 25 owner the thing looks huge. Is it feasible for two medium size adults to comfortably raise this size and weight of mast, with some type of raising system, without too many problems?Finally, will our 3 litre, V6 Mitsubishi Montero be able to do the towing? (We don't mind going slow!) Any comments appreciated,Thanks,Andy
