fin keel repair
by Rimantas Aukstuolis 13 Apr '24

13 Apr '24

I own a 1983 Montgomery 15. Last summer was my first time using the boat due to the pandemic and some other health issues but I did manage to launch and keep at a dock on Lake Pymatuning (OH/PA border) from August to September. Apparently the boat was always dry sailed, and never had anti fouling paint applied as the bottom was clean when I bought it almost three years ago. When I hauled it out (dumb me) there was algae on the bottom. I was able to get it pretty clean using a marine algae cleaner and powerwasher but I'll give it another hit in the spring. As I was powerwashing, I seem to have removed a 3" section of fiberglass from the fin keel, forward on the port side. Looks like exposed metal. Is this lead or steel? Can't see well in there. How should it be fixed/patched? I really don't want to apply anti-fouling paint and will dry sail after I modify the trailer with keel guides and slicker beds to make launch and recovery easier. Any suggestions on repair and trailer mods are appreciated. Thanks Rimantas "Ray" Aukstuolis

Bow pulpit. My boat did not come with a bow pulpit. Is there any resource for getting one made or used.

Keel surgery pics I saved
by John Schinnerer 24 Nov '21

24 Nov '21

Hi all, Re the keel surgery thread - found these in my stash of pics I've saved, often from posts on this list. Originals are too big to have been posted though so must have got them some other way. These should be small enough to post, if someone wants the full size images I can send direct to your email. Folder I saved them in is called "Jim Hymes keel surgery" and that's all I know other than what they show - portions of keel cut open and some removal of rusted steel-resin innards.

11/21/21 Update RE: 8/23/22 Update Re cracked shoal keel drill results
by tdelacy＠wavecable.com 22 Nov '21

22 Nov '21

For and about Montgomery Sailboats, Update: The boat is off the trailer, the center board is removed as well as approximately 9 lbs of steel ballast from the starboard shoal keel just forward of the center board pivot pin. Question: If I am successful in sealing the shoal keel water leaks, what do you think the probability that steel ballast will continue to rust and expand resulting in future cracks? Background: 1. The shoal keel that I have opened is dry. 2. The ballast is very cohesive. Some of the punchings have actually fused into solid lumps. 3. Port side is not cracked. 3. I am concerned with the amount of shoal keel skin that I would need to remove for ballast access it will be difficult to retain the shoal keel shape. 4. For my current situation, it is actually easier to obtain lead shot to replace the steel ballast. Because lead density is 1.44 times greater than steel, I believe I will have a noticeable lower CG on the starboard side if I only replace ballast on the starboard side.

From the time the tree fell until I was able to relocate the trailer into a replacement metal tube and fabric structure was several months during our raining season.

Combine the elevated interior temperature with our unusually hot summer and it is not unreasonable to assume the shoal keel has dried out. 2. Re: picture P8230005. A. This is just aft of the centerboard trunk in hull, starboard side, similar port side. B. Is this a possible water path into the shoal keel? (1) Water could easily enter this opening after the sump filled. (1) Should I seal these openings or are they intentional vents? 3.

I am assuming my sump is water tight, see P8230007. A. You usually do not get that nasty growth if there is a reasonable exit water path or the shoal keel is water tight and was completely filled with water.

I can see RUST inside that crack which indicates water. Water freezes and expands and cracks the keel. This happened on Miss T a 17 owned by John Edwards and that crack is the same. John actually bought Tom Buzzi’s 17 recently as a replacement. I don’t see how a tree would crack your hull from the inside out like that.

My M17 saved the ground from being damaged. After removing the debris it appeared the only damage was to the starboard mooring cleat. Unfortunately, today as I began my list of items to restore my M17, I found the exterior starboard centerboard shoal keel was cracked from the tree fall damage. The previous owners had taken good care of the boat and the shoal keel was not cracked. I suspect the force of the tree impacting the starboard stern mooring cleat raised the boat bow up and gravity slammed it back down upon the trailer. Do you have any references of how I should proceed? I did quite a bit of epoxy repair to my former harpoon 5.2. I am looking forward to venturing into polyester fiberglass with gel coat finish. I could not attain a painted finish as good as the gel coat. However, as this is the underside, I am leaning toward rebuilding the surface with epoxy? Additionally, re: the stop pin. As I do not intent to race but cruise, do you recommend faring in the stop pin or leaving a proud external stop pin (reference friends early 70's M17). As I am in the Puget Sound region, I expect I will have to pull and recoat the centerboard every 5 years. It just seems an accessible stop pin would be beneficial.

Ballast replacement
by Jon Barber 22 Nov '21

22 Nov '21

My M17, Ol'44, hull # 44 had the dreaded iron shot originally. Sean and Bob E did a fine job replacing not only the ballast but the entire keel. Photos are available somewhere. I will try to add them to my MSOG photosite page. The new ballast is lead. Problem solved. The other advantage to using lead ballast is choice of placement. Since lead by weight takes up less volume, you can decide where to put it. Sean said he moved the new ballast forward to compensate for crew weight in the cockpit. Does this give me an advantage against other 17's? Possibly. This is a fast boat. The floor was cut out inside the cabin to fill the void with lead. I call it a scar. It is slippery, so I covered it with a non skid vinyl "floor". The work was definitely first cabin. Another fine vintage boat saved from the wreckers!

New Montgomery 15 Rudder Blade and Questions
by David Grah 19 Nov '21

19 Nov '21

I just received the new rudder blade I purchased for my Montomgery 15 from Bobby Chilek at Bobby's Boat Works and it is really great. Our old blade I think was original with the boat built in 1986. It had split top and bottom and had a run-in with a propeller at some point along with a number of other bruises. Recently I had filled all the various divots in it but have never been satisfied with the result. The new blade is nicely shaped and finished, is a little wider than the old blade, and its pivot hole is in a slightly different spot. All in all, if you're thinking about a new rudder blade, I'd recommend Bobby's. Fitting the new blade in the rest of rudder assembly got me to thinking about the condition of the aluminum rudder cheeks (I guess that is what they are called) and what I can do to rehabilitate them. The issue with them is primarily wear in some of the holes in the aluminum, most significantly the pivot hole for the rudder blade. The pivot hole in the aluminum cheeks had significant wear and, a few years ago, I bushed them with some sort of metallic bushing, probably a brass or bronze (the wood of the rudder blade had some play too that I improved with epoxy and re-drilling the hole). Those bushings have worked well reducing the play in the rudder assembly but, over the years, the dissimilar metals of the cheeks and the bushings have developed signs of corrosion. In addition to issues with the pivot hole, upon close inspection, I see the front mounting holes of the bottom pintle are also showing signs of wear. At this point I am wondering if a good treatment for these worn holes in the aluminum cheeks is to weld them over and re-drill them and wondered if any in this community has insights about this idea. I'm thinking some 1/8 inch doublers welded over the welded-over existing pivot holes, welding over the other worn holes, and then redrilling all these holes might be a good way to put more life into those old cheeks. So, my questions: I don't know much about welding, but does this approach make sense? Is there anything I should know about the particular aluminum used for the existing cheeks, the particular aluminum to use for doublers, or the welding materials or process to make this approach most likely to succeed? I realize the doublers could only be welded on around the edges leaving water a place to get between the cheeks and doublers if it got in through some sort of welding flaw. Should I be concerned about this possibility? If so, would it work to develop the additional thickness by welding new material onto the cheeks with no doublers? I assume a local welding shop could handle the welding part. Does that make sense? As always, thanks for any and all feedback, information, and ideas. David GrahBishop Calfornia
