>>> What is the recommended material to use to seal around windows? >Last spring I installed new brass opening ports from NewFound Metals I'm in the process of updating Dolphin's six ports to the bronze ones from New Found Metals, and have used the sealant that they recommend: 3M Strip Caulk. It is intended to be used with automobile glass (although it seems to be in the process of being superceded) and comes in a box full of strips (surprise). It never sets. So far, it looks good, although I wish that I'd bought the white version instead of black. Several auto glass supply houses denied all knowledge of it before I found it in a large old-fashioned auto parts warehouse.

Re: M_Boats: Window & Fitting Leaks - do polysulfide
by Wcpritchett＠aol.com 27 Dec '01

I agree with Theo. Silicone will not stick to fiberglass like polysulfide...been there and done that mistake. Use Boatlife polysulfide and it will be the last time you will need to recaulk. Portholes don't need to be glued in either so 3M 5200 isn't necessary. Bill

Window & Fitting Leaks

What is the recommended material to use to seal around windows? Whatever is there now seems pretty deteriorated; it's probably original--some kind of black substance. What about 100% silicon caulk? Steve & Debra M15 #152

Steve, Scott Grometer is an M15 owner out in the Northwest. He's off the air at the moment - I haven't seen a posting from him in the past month (vacation?) but just drop him a line, and he'll answer in due course. As for a sealant, you want something that seals, but is removeable in the future. not something like 3Ms 5200. Once that's in place you can't remove it without blasting! WEST marine catalog, 1999 edition page 173, gives you a listing of sealants and their recommended uses by product names. If you haven't got a WEST catalog, call them at 1-800-262-8464, and they will send you one. The WEST catalog of boat items becomes the common denominator amongst the M web site people. They just quote item and page number so you can find it. Connie ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!

I believe I'm familiar with the formula you speak of, one that attempts to screen out boats that are too beamy for blue water safety. What I'm looking for is this: how far will an M-15 or 17 heel before it reaches a point of no return and turtles? In the case of my Potter, it's not too far! On my wife and I's first sail, we managed to lay the boat on its side due to a number of mistakes made. Amy Ann was quite content to stay there until I swam around and weighted the CB, whereupon she popped back up and we continued sailing. Thus in real terms I would say that our boat has an ultimate range of stability of less than 90 degrees. With the M-boat's significantly greater ballast, I assume that their range is much higher. I'm confident it's one of the calculations Lyle Hess made and considered when he designed the M-17. Cheers Steve Tyree, P-15 Amy Ann

Hi Steve and Debra, My guess is that you got water in the hull through - window leak - fitting leak - rain under forward lip of companionway hatch while trailering in the rain -water through companionway hatch boards (?) In my case, I had gallons of water in both cabin storage lockers (under the bunks). We had had a nice frolicking sail back across Lake Champlain, and found the water in the lockers when I opened them up to put something away. After emptying the water out of the lockers - P & S - we creened the boat at the dock and found water coming into the Port locker via a hole in the laminate in the aft upper edge. I also had water in the bow locker too (the areas aren't sealed very well), so any water will migrate fore and aft in a seaway. You will find that you will get squirts of water from the centerboard slot in the cockpit if you hit a motor boat wake. The water was also gurgling in while we were sailing - well heeled. I subsequently found the actual leak was at the aft end of the centerboard slot. I determined this by filling the boat with water until it started dripping out of the centerboard slot at the bottom of the hull - now I had the where: then next question was locate the exact spot where the leak occurred. To solve that problem, I built styrofoam hatch boards: cut a hole for my shop vac hose in one panel; and sealed everything with duct tape. Then I inserted the shop vac hose in the hole: taped it in place, and fired up the shop vac. to build up pressure inside the boat. Then I painted the centerboard slot area with soap suds, and Voila, ...big fat bubbles coming from the aft corner of the C/B slot. The rest was easy. I opened up the leak area; filled it with epoxy mixed with a filler, and let it cure. Problem solved. In your case, I'd pump out the water and go for a sail to see if this was rain water from trailering / standing, or if it is really a hull leak. If you dry it out, and you don't find any water after you've been sailing, then your problems are solved - it was rain water leaking in from above. Why head for the Apostle Islands, when the Lake Huron islands sound so appealing???? Connie Connie ________________________________________________________________ GET INTERNET ACCESS FROM JUNO!

Steve, Can't help on your stability question, but Scott Grometer is the man to contact regarding long range cruising on an M15.

Steve, I charted an O'Day 27 out of Bayfield in 1987. Had a great sail. There is an outside chance I will take my M17 up that way next summer (probably August) to sail the Apostle islands. If it works out I would enjoy having company; I'll let you know when I know for sure. John Miss T M17 # 372

Re: M_Boats: Good Book !

I have a copy of the movie "Riddle of the Sands". It is beautifully photographed, and while they did change the story some, they didn't harm it. The opening scene with Carruthers (Michale York) at his club, bored out of his skull when he gets the letter from Davies always gets me in the mood to enjoy the rest of the movie. When they show scenes of Davies singlehanding his Dulcebella (a converted 37 ft lifeboat) in the shallow Freisian waters, I get very envious. Needless to say, I like the movie, but I like the book even more. I read Shadow of the Sands, and enjoyed it, but liked the Riddle of the Sands better. If you haven't read Riddle first, Shadow will be a bit confusing. John Miss T M17 #372
