With all the barrier coat and bottom paint removed, holding a straight edge vertically inside the trunk, the opening *at the bottom* is uniformly ~0.020" narrower per side (0.040"+ total) for both sides. The board jams at the very bottom of the slot when raising or lowering. Is that how the boat was built? Maybe to minimize flopping of the centerboard when lowered? This area of the trunk needs to be sanded away to make clearance for bottom paint. Never mind a barrier coat. Jeff

It didn’t appear glassed over. The surface under the gelcoat is black maybe a fairing compound? Also the pin is a cut off 3/8 bolt. Did Jerry use a bolt for the pin? Maybe there is some repair history? I just bought the boat last fall. Jeff On Wed, Jun 22, 2022 at 9:56 AM Bill Ahrens <billahrens@comcast.net> wrote:

Jeff, I’m out of the country just now, im pretty sure Jerry is as well. Where are you ? I would highly suggest that you be carful not to throw out the baby with the bath water. Might be that someone did the trunk bottom leak repair. Start by doing as little as possible to get a little clearance, check for sand and muck build up from beaching. There’s help and experience around. Don’t make too many assumptions just yet. Take care with the pin, it can be a pin or a bolt but when folks get impatient they can cause damage to the area and leaks may happen. Then it’s off to the rodeo! Stan Sent from my iPhone

The board doesn't appear to be glassed but the trunk appears to have added material at the bottom around the slot opening that reduced the clearance with the board to zero.. Original construction or later repair - unknown. It's plain to see by holding a straightedge vertically in the slot. I sanded the material down enough to allow free board movement with 2 coats of bottom paint. I'll know tomorrow when the board is reinstalled if I'm successful. The board and trunk will not have any barrier coat since I removed it when the jammed board was discovered. A lot more material would need to be ground from the trunk to allow clearance for barrier coat. When I first launched the boat after purchase, I noticed a slight bind when lowering the board. I thought at the time that the pennant was binding somewhere when in fact, even without bottom paint, there was interference between the trunk and centerboard. I'd be very interested to hear Jerry's opinion. Jeff On Wed, Jun 22, 2022 at 9:29 AM Stan Susman <stanpfa@pacbell.net> wrote:

Jeff. To my eye it looks like the trunk is not lined up with the slot in the hull. There is a visible seam. The trunk should be sitting on the inside of the hull so the joint is visible inside and along the trunk, not easily see. From the bottom of the keel. See attached where I've highlighted the seam. I can also see voids in that seam (on the right side.of the image I've run some red lines representing the seam and with some purple representing the voids). On the Facebook MSOG page SeanM has posted details on a M17 he is recommissioning.

After looking at the photo, I'm with Dave- is there any give if you reach up and press the trunk walls outward so that the vertical edge meets the edge of the hull? It really does looks like the hull trunk joint opened up- if you poke in the voids, what do you hit? On Thu, Jun 23, 2022 at 1:49 PM Dave Scobie <scoobscobie@gmail.com> wrote:

Its 100% Solid. No movement. There is a gap as the picture shows but no failure or void in the bond. Its hard inside the gap. Feels like epoxy. There was no water inside the keel. Going back to the original issue - the slot is narrower at the opening than elsewhere and required grinding to eliminate binding centerboard. Is there a relationship between that and the gap?

Thanks Dave. Its 1992 model. #496. Looks like the same situation as Sean’s. Wonder how such a separation could occur and in my case not cause a leak? A lot of material will need to be ground off to make room for glass tape. I already ground off quite a lot to clear the binding board. Do you know the thickness of the original layup? I still wonder why the slot is much narrower at the bottom. In any event, repair will happen next spring before launch as I’ve already been hauled out 2 weeks.

Attached is a photo of the trunk before I did anything to it. I don't have an after photo. There were no leaks or issues other than a slight bind when lowering the board. The only reason I was in there is for barrier/bottom paint.

The board doesn't appear to be glassed but the trunk appears to have added material at the bottom around the slot opening that reduced the clearance with the board to zero.. Original construction or later repair - unknown. It's plain to see by holding a straightedge vertically in the slot.
I sanded the material down enough to allow free board movement with 2 coats of bottom paint. I'll know tomorrow when the board is reinstalled if I'm successful. The board and trunk will not have any barrier coat since I removed it when the jammed board was discovered. A lot more material would need to be ground from the trunk to allow clearance for barrier coat.
When I first launched the boat after purchase, I noticed a slight bind when lowering the board. I thought at the time that the pennant was binding somewhere when in fact, even without bottom paint, there was interference between the trunk and centerboard.
I'd be very interested to hear Jerry's opinion.

Agree with Dave and the others. The sides of the centerboard trunk should be flush with edges of the slot in the keel, and there should be no gaps. If you had steel ballast, we would know exactly what happened. With lead ballast, it is more of a puzzle. Maybe water got trapped inside the centerboard trunk and froze? -----Original Message----- From: Jeff Orlando <jeff.orlando@gmail.com> Sent: Thursday, June 23, 2022 4:13 PM To: For and about Montgomery Sailboats <montgomery_boats@mailman.xmission.com> Subject: M_Boats: Re: Centerboard jams - update Attached is a photo of the trunk before I did anything to it.

Just to clarify in my mind…The boat is a ‘92 with a fiberglass board, not cast iron?

Did someone glass the board?

With all the barrier coat and bottom paint removed, holding a straight edge vertically inside the trunk, the opening *at the bottom* is uniformly ~0.020" narrower per side (0.040"+ total) for both sides. The board jams at the very bottom of the slot when raising or lowering.
Is that how the boat was built?
Maybe to minimize flopping of the centerboard when lowered?
This area of the trunk needs to be sanded away to make clearance for bottom paint. Never mind a barrier coat.

The boat is 1992. From things I’ve read, it should be lead ballast On Thu, Jun 23, 2022 at 1:37 PM Mike Z <speedernut2@gmail.com> wrote:
