Re: Full or fin keel?
OK. Good stuff given so far. One point to keep in mind; if you decide to go with a fin keel I suggest you do NOT get a wing keel, just to get a more shallow draft. Since you will run aground at some point in time, the wing keel severely limits your options on getting yourself back afloat. (Yes, I have wing keel now, haven't been in trouble, but would not again get a boat with such a keel). The comments about the manoeuvrability of a fin keel in close quarters, compared to full keel, are not to be ignored. You'll thing of them whenever you visiting a marina (which will be unknown territory in many cases) - both when coming in (forward, let's assume) and leaving (backing out).
Best of luck with your eventual purchase!
