Jerry: While you are on the subject of CB trunks, etc., can you recall at what level the steel ballast started on the early M17's? Did the pivot pin forward or stopper pin aft either one pass through the ballast? Also, I did you ever factory install a flushing marine head with holding tank on M17s?

Looks like you're talking about water getting into the bilge. Since you say that there is no damage on the hull, including the bottom of the keel, I'd guess that it's coming in thru the top of the CB trunk and working down from there between the trunk and the trunk housing part of the hull liner. What is the year your 15 was made? On some of the very early boats (1981 or 2?) we had that problem and cut down the trunk cover a little so that I could visually inspect it while under construction. The problem was the glass bond between the trunk itself and the underside of the deck would have a void. After we cut down the top of the trunk cover a little I could see and feel around the drain bond.
There's always the method of waiting for a warm, sunny day, filling the bilge with water and taking a cooler full of beer and stretch out below and see where the water comes out!

Hi Jerry. I enjoy reading e mails from you on the Monty site and learn a lot from them and those of other owners . I have two questions which probably only you can answer. First my M 15 was built in 1981 and has a 19 ft mast. You have given the rig dimensions on the owners site as I 15.33 J 4.58 P 16.83 and E 7.83 for the M-15. Do those measurements hold true for a boat with a 19 ft mast which I believe is slightly shorter than used on your later boats? Next my boat takes on water into that box- like space approximately under the thwart in the very bottom of the boat. I suppose the space holds about a gallon of water and it requires pumping out about every 10 days. The water accumulates faster if the boat has been heeling a lot. The top appears to be well sealed to the hull along the gunwales,no evidence of leaking there.. There is no sign of damage on the hull or keel and of course at 6 ft 2 in and 82 years of age there is no way I can get a look into that interior space.My boat is on the hard under a snow drift till April, but a younger,smaller, boat savvy friend and I will try again to discover the source of the leak come spring . Have you any advice on any techniques or tricks which we might employ to diagnose the problem ? Your advice will be much appreciated The leak poses little danger to those using the boat, but it is a bloody nuisance, particularly because if we can’t find the source we certainly cannot fix it. From a frustrated M –15 sailor. Have a good holiday season and all health in 2013. RTH. PS the M-15 has been a great boat for me and a source of great interest and admiration among the” big boat” people at my yacht club.
