replacing the center board pennant
My Montgomery 15 needs to have the center board pennant replaced. I've read the archives but still have some questions. 1) Does the pin have to be removed? 2) Does the board have to be completely removed from the boat? 3) Is it alot easier taking the boat to a boat yard relative to raising the boat on blocks yourself and replacing the pennant? 4) Do you need assistance raising and lowering the board? Thank you, Rich Cottrell
Rich The entire board has to be removed, hence the pin has to be tapped out. The boat has to be raised and the boards pin tapped out and the board lowered enough to remove it. We use a 5/16 line with the core removed and a figure 8 knot tied in space inside the side hole area (the 3/4 inch diameter hole in the side of the board) I put a drop of 5 minute epoxy on the knot area to prevent any un-raveling later) Then the board can be raised back into place (it weighs about 40 to 48 pounds) and the pin tapped back thru the holes. Then adjust the line with a stopper knot so the board will come down and "almost" touch the forward face of the trunk and tie another figure 8 knot in the top of the lowering line so when the board is released, the knot will keep the board from phyically hitting the face of the trunk. (the knot hits the top of the hole in the cockpit and stops the board from going down any further; Also the knot will keep the squirting to a minimum when the board is down, it almost plugs the hole) Not doing this last procedure will put stress on the pin area and eventually the board will break at the pin location. You want the board to hang on the pin at the forward part and on the centerboard pendant (5/16 line) at the rear area, without the board touching the forward face of the trunk. (which causes a prying stress on the pin) When you tap the pin back into the hole, squeeze some caulking in the hole and on the pin. Wipe any excess off. etc. This is a 2 man job because someone has to pull the pendant line when you are lifting the board "Up" into the trunk, etc. You would be surprised at how heavy this board is so be careful. Have some help when you lift it. Its just an awkward shape. Note that all Montgomery 17s built after 1987 also have the same board and procedure that the Montgomery 15 has. The Montgomery 17s built with the fiberglass board (both boats have the SAME centerboard) after that 1987 date do not have a centerboard stop pin. The stop pins discussed these last few days are on the pre 1987 Montgomery 17 boats only, with the Cast Iron (160 pound) centerboards only. On those pre 1987 M_17s the centerboard is cast iron and raised with a winch with the pendant (line) coming up into the cabin area. That's why the complaints of squirting water in a chop with water collecting inside the cabin. On later boats (after 1987) all the pendants exit into the cockpit area, hence no water problems. Early boards had steel shot (40 pounds) later boards including our current boards have Lead shot (48 pounds) and thats why the different weights. Fair winds Bob Richard Cottrell wrote:

Rich, I replaced the centerboard pennant on my 1988 M15 quite a few years ago by anchoring in calm water and letting the board rotate down and hang on the pin. It took a few free dives under the boat to get the new rope in (especially since I had to figure out the trick of removing some of the rope's core). I don't remember how I got the new rope down but I probably taped the top of the old rope to the new one and pulled it down. I don't recall it being too difficult and I was able to do it by myself without having to remove the board or lift the boat. -- Brian Ripley '88 M15 #421 Roseville, CA --- Richard Cottrell <rc2222@pacbell.net> wrote:

Bob, Thanks for the excellent response! Rich, Relative to question 3) Is it alot easier taking the boat to a boat yard
relative to raising the boat on blocks yourself and replacing the pennant?
Many of the VA State parks have hoists to put small boats in the water. Your local racing fleets would know where they are located in your area if there are any. Just don't try it on race day :-) I empty the boat and rig a triangle from the stern and bow cleats that centers about 6- 10 " forward of the forward edge of the bridge deck. With this arrangement you can hoist the boat off the trailer, pull the trailer out, slip in some safety blocks and lower the CB. Before doing this I removed the stopper knot in the existing pennant, whiped a thin line to the end of it, whiped the other end to the new pennant. Lead the line through the mainsheet cleat on the bridge deck and outside the boat so that you can control the raising and lowerering of the CB without being in the boat. I believe this can be done without removing the pin to the CB. I was replacing my CB at the time and can't honestly remember. If you take all of the tools with you can cover it all in one trip.
