Thanx Stan, The proto should be heading back to Sac as soon as Jerry is ready. I'd be pleased to have you stare at the config. sal In a message dated 11/26/2010 3:46:18 P.M.

Just referring to the lift pennant now .We found a special shackle ,slightly long with a hole at the top of the strap. We simply attached the shackle to the board put the pendent through the hole in the shackle slipped on a nylon washer to help spread the load between the pennant and the shackle and tied a figure 8 stop knot . the beauty of this system is that the knot is all trapped under the shackle and shortens the need for room between the top of the centerboard and the glass trunk, (at the hole) , Also the top of the shackle acts a a tough pendent stop instead of jamming and wearing out the old style bowline knot. Sean, we can talk off line about ideas on a easy fix on the 23, Mine was a fixed keel so I'm foggy on the pendent/access issue,but I'd wager we can do an on trailer fix. Sal, I'll stare at the config. on the prototype when it's back in flat Sac. I'm in full agreement that all systems should be owner maintainable W/O much BS involved. The repairs above were done with one of our newest M-17 paternal brothers Bill Genevro who has a rather long list of engineering successes with mast design and construction, and now aviation related items among other background in product and process adventures. Welcome aboard Bill.

Since both boards are steel they have both needed maintenance that my fibreglass encased M-15 board did not. I have had both blasted and coated etc. to keep them from rusting. As far as weight it would be a compromise like most things, I know the center board weight is different from the keel weight in that the lower center board provides a lower center of gravity which helps the moment arm formed with the main sail center of effort or whatever the term is. I don't have any bright ideas about the pendant access since your really need some room to work ideally if you are going to unscrew the shackle and change out the pendant. Not sure an access hatch would really do it, but it might. If it could be possible to "overextend" the board with the stop pin removed but pivot pin still in that would simplify replacing the pendant and or shackle somewhat. Seems like that might be possible to design in. I do know that the 150lb board was much more user friendly in that it could be handled by one or two adults without much problem vs the 350lb which requires hydrolic assist and lots of planning to move and work with it. So if possible I would stay toward the 150lb end of the scale. Cheers Robbin On 11/26/2010 2:26 PM, SALGLESSER@aol.com wrote:
Hi all, As some of you know, my wife Gail and I are involved in the development and eventual production of a new Jerry Montgomery design called the
Sage 17.
As all trailer sailors know, a shoal draft offers real advantage in launching and sailing shallow waters. Also, as most sailors know, going upwind efficiently is best with a deep keel. Some feel the bigger the stick, the deeper the keel. The keel-centerboard is a logical synthesis of the two needs and that’s why Jerry Montgomery and Lyle Hess chose this option. In fact, as I understand, the early Monty 17’s had a deep (3’7”) keel and the design was later adjusted because of the associated problems (launching& shallow water) with a trailerable deep keeled sailboat. I have followed problems with the pendant on some of the Monty forums as well as the current dilemma Sean Mulligan is facing with his pendant on Dauntless. Gail and I feel that the owner of any product should be able to perform, with the assistance of the factory, maintenance and repairs on their product. As Robbin suggested, early thinking of this problem would be beneficial. The Sage 17 is a keel-centerboard design with a fiberglass / lead centerboard of approx 150-250 lbs (pending Jerry's decision). While we’ re in the development stage of the boat, we'd like to find and incorporate a “ built in ” solution to the pendant / centerboard maintenance question, preferably without using a hoist. Jerry has come up with some well thought out ideas on centerboards, but we would also like to solicit any thoughts or solutions that trailer sailors, especially Monty sailors might have entertained. It would be nice to offer a new Sage 17 to any great ideas, but it is a bit beyond our means. We can offer a very nice high quality knife to anyone that comes up with any idea that we use. Pending Jerry’s approval, of course. Thanx in advance for your thinking time.
