Hi, Don I have a 17, so I'm not quite as familiar with the 15's proportions, but have you considered a strongback? What I'm envisioning is something that you could clip to the hoist and lower into the cabin (companionway hatch slid fwd). It would span the width of the top of the coachroof and be contoured and padded to distribute the load. Then a cable or cables could be run to the bow or stern to steady it. That way you wouldn't be adding extra holes and fittings. Just a thought. Your results may vary, etc. Tod -----Original Message----- From: montgomery_boats-bounces@mailman.xmission.com [mailto:montgomery_boats-bounces@mailman.xmission.com] On Behalf Of Ludlow, Don Sent: Tuesday, December 02, 2003 4:44 PM To: 'montgomery_boats@mailman.xmission.com' Subject: M_Boats: RE:Lifting an M-15 I did an experiment to find the center of gravity of an M-15. I rigged lines from the two side cleats and the bow cleat to the hoist hook then lifted the boat up off the trailer. At first, I set the harness some 6" forward of the companionway hatch and the the boat lifted stern first. I kept adjusting the harness until I got the boat to lift level. The center was 8" aft of the shroud connections with the mast up. I'm considering installing two "U" bolts, one on each side at this point, located through the rubrail. This area has a channel shape, and is where the hull and deck sandwich togeather so it should take the load. I've heard that they have used the shroud fitting to lift M-15's at the factory and it is bolted through this point. I've checked 5/16" "U" bolts in West Catalog which have working loads above 1600#. I would run a safety line to the bow and stern cleats to help hold her level and also tak the load if a U bolt failed. Any comments.

From the spec sheet you sent me : the board goes down to 40 inches - 21 inches = 19 inches, and the total area is 2.65 sq ft, I am taking the mathematical center of that area and building a dagger board to fit in the slot with the same centers. Just to see if its work out before continuing with the stainless board. I'm using 1/4 plywood as a model board.
It looks like I can do a positive flotation but I will lose almost 1/3 of the interior storage space. That's a lot and I wonder if there is any other way to do it. I have plenty of scrape wood around to change my mind if it does not work out. I 've said I wanted to come back in the next life as a rich stock broker, But I just learnt what the U. S. Senators make, so I'll just change my mind on that too. ;>) Mike ------------------------------ Message: 2 Date: Mon, 24 Nov 2003 19:13:03 -0500 From: "MC Carpenter" <southisland2@earthlink.net> Subject: Re: M_Boats: older M17 history archives To: "For and about Montgomery Sailboats" <montgomery_boats@mailman.xmission.com> Message-ID: <002901c3b2e8$e5f2d780$a3154bab@D60D0Q21> Content-Type: text/plain; charset="iso-8859-1" Mark, Is that line across the board the previous water line, its the line just below the pivot point at the bottom of the picture.
