Bob, thanks so much for your kind welcome. I do have a question you may be able to answer, or perhaps someone else out there can. I mentioned briefly what I fear may be a leak in the centerboard trunk area of my M-15: there is water in the keel sump and also in what appears to be a narrow space between the outer and inner hulls(?) directly below where the porta-pottie sits. There are several good descriptions in the archives, from people who have had a similar problem, of how to find and fix the leak. I guess what I'm really wondering is -- is there available out there some kind of drawing or diagram that would show exactly how the M15 (specifically here I'm thinking of the CB/keel area) is put together? I don't have a clear picture of how the centerboard trunk is sealed out (isolated) from the space between the outer and inner hull. How is water able to communicate between them (I guess it's not supposed to right?) Is it that the centerboard trunk walls are attached and sealed directly to the inner hull (floor)? Does anything prevent water that has found it's way between the inner and outer hulls in one area, from travelling to any other area of the boat? I remember from my gear-head days that you could always get books with diagrams of how things went together in your CAR (that's back when you used to actually be able to tune up your own engine -- shows you how old I am) but I suspect such things would not be available for sailboats, yes? I realize that at the end of the day, I just need to establish precisely where the leak is, if any exists, and fix it, and that theoretical understanding is not necessarily required for that. I'm just the curious type I guess.

I'm happy you found a suitable Montgomery 15. I know you and your wife will enjoy her for years to come. I also appreciate your comments about Cruising World Magazine. It does seem that they only cater to the gold-plate crowd and have left the small boat sailor behind. I know that your comments are accurate and at the same time somewhat tongue-in-cheek :-) If you need any help or advise this is the place to ask. If I can help just give a call.
