Thanks for the replies! I'm going to try to attach a couple photos. If they come through, one is the underside of the lapstrakes, a few areas with lots of little holes (bubbles when applied?) And a flat area with similar sized spots. Fill the holes with my epoxy fairing? Then prime over it all? -Gerry

Project: Replace rusty steel in keel with lead!
by James Hymes 25 Apr '19

25 Apr '19

My current project to remove rusty steel punchings and then to replace with lead shot NOTE: I can testify as to the weight of the steel I removed from the keel in my current project weighs a total of 224 pounds, give or take 20 or so pounds. That plus the 175 pound centerboard totals 400 to 425 pounds of ballast total on my 1975 #69 (not Coyote- may name her “Ole yeller” since mine is got the same number as Coyote) M17. When the centerboard would drop, my boat sailed quite exceptionally, well balanced, pointed very well….Jerry has posted that when he switched from steel to lead he increased the total ballast weight to 600 pounds from 500 or 550 pounds. Anyone doing this project, I recommend weighing how much you remove and replace with same amount of lead unless wanting to change characteristics. My prior project: to cure problem of rusting steel slugs on account of the CB would not drop (from the outset of my ownership of hull 69, I had to jump up and down inside the cabin to get the CB to drop; additionally I drilled an exploratory hole at the fore bottom of the keel from which water did pour out of): Some years ago, I drilled ¼” holes throughout the outer walls of the keel. I then injected ?epoxy into one hole at a time, so that the epoxy would fill up air pockets inside the keel to prevent water from rusting the steel slugs. I injected the epoxy into a hole until epoxy oozed out an adjacent hole, then plugged the hole injected into with a wooden dowel. I injected from the bottom of the keel upwards. Near the top of the keel I found void, as in no steel slugs, and also a green Styrofoam for floatation purposes apparently. I also at this time removed the CB and had it sandblasted, I then refaired it and painted it with bottom paint, or whatrever was appropriate. The CB did drop as intended after this for several times. But then it quit dropping again. My current project to remove rusty steel slugs (phase 1) or steel punchings (224 pounds of centers of washers approx. 1/8th “ diameter) and then to replace with lead shot (available in 25 lb bags at cabella’s $43.50 per bag and elsewhere: I started with boat on trailer, used a cutout tool to cut out sections of the outer keel wall…. Found the steel slugs to be very rusty and also found the epoxy that I injected previously to have formed an extremely difficult mass to remove. I began with a hammer and chisel to remove rusty steel. This resulted in trauma to elbow resulted in severe case of tennis elbow with some of the rusty steel removed. I found a boatyard whereby I paid for 3 weeks for them to put my boat on stands (would have preferred them to raise it higher than they did for my comfort). I then bought a cheap air hammer, progressed up to a higher quality air hammer and finally got an Ingersoll Rand 122 MAX for $169, along with finding a general laborer to use the air hammer. This air hammer was very capable of removing the steel/epoxy supertough mess. A word of warning: There is a mass of the steel slugs/epoxy at the front of the keel , fore of the centerboard that goes up to the bottom of the hull, this is located directly underneath the compression post – I suggest leave this section as is – I believe it is the foundation for the compression post. Anyways, got the steel removed and lo and behold: the centerboard drops easily!!! :) Phase 2: To re-fiberglass the cutout areas of the keel: I did cutout 4 sections of the outer keel wall on the port side, and 3 sections on the starboard side in order to access the steel punchings. The fiberglass man is to do the repair AND leave the gap between the outer wall and centerboard trunk wall to allow for me to be able to (phase 3)pour the lead shot from above (I will drill holes through the sole above the areas of keel to pour the lead shot). Additionally, he did notice there is lamination damage at the bottom of the centerboard slot of the keel that needs repair. Phase 3: I drilled a 3” diameter hole in cabin just aft of the compression post where I will pour lead into the front of the keel. Since I did remove the steel punching mass that was underneath the compression post, I need to be able to pour the lead there and then be able to pour epoxy to make that area hard and compress it so that it will support the compression post above. I will put in an inspection port at that hole to monitor inside the keel for compression post support, water, etc. I will also drill small holes at three locations on each side of the centerboard to allow me to pour the lead shot down between the centerboard and outer wall of the keel, as well as one above the rear of the keel Phase 4: I did remove some of that green Styrofoam flotation, and so may replace it and place the new Styrofoam inside plywood boxes and fiberglass them to the centerline of the boat at the hull. If this project is a success (really my only concern at this point is how well he can repair the cutouts in the keel walls), it might be worthy of being posted in the projects section of the site.

Re: M_Boats: looking for input on gelcoat application on M-17

I am sure your will get many similar thoughts but I have stripped bottom paint on my M-23 and done gelcoat repair on large section of my M-17 and under the water line you want to use barrier coat. Either Interlux or Petit would be fine but there is no reason to go to all the effort of gel coat if you are going to paint over it, as you will below the water line.All the best!

Here's the deal; we stripped all the paint below the water line since we didn't know what it was, and it needed refreshing. I also removed a through hull, and redid a couple old through hull patches I found because I didn't like the looks of them. As we removed paint we found many areas (particularly under the lapstrake edges) where the gelcoat had been previously been sanded through. And of course I have the new repairs I did.

Re: M_Boats: M15 rusting ballast from Sam <shunter@gmail.com>

Hi Alex, I have an M15 (built 1984, #272) which gets some water in the bilge. The source was a mystery for a long time, but after some close-quarters cell-phone camera work, I found that there were some openings in the join where the center board rope runs and/or cockpit drain exits. I'm pretty sure now that when water is coming back up through the drain in the cockpit, a tiny amount is also entering the bilge. The rate at which it collects seems to vary, I think depending on sailing conditions. Now that I know about it, I try to check on and remove the water after sailing trips, but I figure that the boat has survived for ~35 years with this situation, it will probably last a few more. The worst I've ever seen it was after a little over a week and quite a few miles in the Gulf Islands. I pulled maybe 3 liters of water out after that trip. Maybe this year I'll try to stuff some plumber's putty in the gaps, but the join is quite irregular and I'm not sure anything will stick or form a decent seal. Here is a photo showing the top of the bilge and the join: image.png And another with the camera a bit lower and closer showing the gap in the join between the cabin and the keel/bilge (top left/port corner). You can see that things got a little hairy with the fiberglass.... image.png Finally, the the bilge where you can see that some of the exposed bits of ballast have rusted a bit: image.png All is not doom and gloom however, I just re-upholstered the cabin cushions and really like how they turned out! image.png Sam On Tue, Apr 16, 2019 at 2:47 PM Paul Baker <avalonjazz(a)gmail.com <mailto:avalonjazz@gmail.com>> wrote: Interesting Montgomery 15 story totally unrelated to this pivot pin and ballast conversation: At one point in my life a few years ago, I moved to a house where I no longer could keep my 15 on her trailer in the driveway. There was no space. A man I had done some work for had a factory with a huge parking lot in the back, with a gate and security. I called and talked to him, and he kindly let me temporarily store my boat in his lot. I covered her with a plastic tarp in a way that would allow rainwater to roll off. After it was there for about 6 months, and an unusually heavy rainy season, I had an uneasy feeling about my boat, and made a trip to check up on her. The boat had been moved by the man's employees, and my tarp setup was moved in order to roll the trailer to a different spot. It was never put back in place. During all the rain, the tarp laying on the aft end of the boat had formed a waterproof membrane and the cockpit was filled all the way up to about a half inch of spilling through the companionway door. When i saw this, I panicked. I knew that i couldn't pull the plastic up. I knew the only way to empty the cockpit was to slice the plastic and let the water drain into the self bailing cockpit. I couldn't imagine the weight of that water. I climbed up onto the boat to find a place to make a cut. I was so upset, that it hadnt occured to me that the trailer tongue which was up on a block made this a very unstable situation. When I stepped onto the boat, my added weight tipped the scale. The water started to rush aft, and the boat crashed aft end into the parking lot, with an unbelievably powerful force. The boat was bow up at a huge angle, which frightened the heck out of me to see. I had fallen down into the water as well. I got up, got out of the boat and somehow got her back down again. I think I may have just moved forward, I'm not sure anymore because I was so upset. I had just assumed that my prized boat that I took such good care of was going to be smashed, a total loss. I felt devastated. I was on the ground, and walked aft to see the trajedy. Here's the happy ending: Not only was she in one piece, there was not the slightest crack, chip in the gelcoat. Nothing. I kept running my hand on the point of impact. Not the slightest damage could I detect. It landed right on the tip of the aft part of the keel, so I assumed it would be less stout than other parts of the hull. I was wrong. I realized at that moment how strong this boat actually is.The other huge gift from above: not one drop of water ever went below, which would have been a disaster. Now I keep her in the driveway of my current home, under a covered frame, so I don't have to worry again. *Miracles DO happen.* On Tue, Apr 16, 2019, 1:56 PM Alex Conley <conley.alex(a)gmail.com <mailto:conley.alex@gmail.com>> wrote: > Thanks Jerry- knowing the hump is separate from the keel cavity eliminates > all my worries.

Furler again
by Henry Rodriguez 23 Apr '19

23 Apr '19

I finally ordered a new jib furler for my M17 Monita. I ordered the Schaefer Snapfurl CF 500 from Judy at Hydesailsdirect.com. The price on the website is $768, which is very close to Defender’s. For comparison, the CDI FF2 is $617 at Sailrite.com. I emailed Judy with some questions and she said her price was actually much cheaper at $593 but she was not allowed to advertise the lower price. I asked her if this was a one-off or if the $175 discount was available to all sailors. She said anyone can order it at this price from her but you have to email or call her first. If you just order from the site you will be charged the full $768. There is a $54 shipping charge, and it comes directly from Schaefer. My final cost, including shipping was $647. I am having a new tanbark 150 with foam luff built. I will convert either the 110 or 135 for roller furling. Suggestions? I have also added a removable Solent stay for use with the storm jib. I will be offering the “old” tanbark 150 and 135 (or 110, depending on which I decide to keep) for sale on the msog site. The sails are 4 years old but have only been used for parts of two seasons. Monita did not hit the water last year. It was Chiquita’s turn for the lake mooring. Henry -- Sent from Gmail Mobile on Windows 10 phone

Trim Ballast
by Henry Rodriguez 22 Apr '19

22 Apr '19

Jerry, My M17 #310 has a platform for a holding tank under the forward part of the V-berth. I removed the holding tank when I first got the boat 5 years ago. Is there any advantage, from a “trim” standpoint, to moving the house battery to this location? That would get its weight forward by a couple of feet, maybe offsetting my own considerable “ballast” in the cockpit. Henry Monita -- Sent from Gmail Mobile on Windows 10 phone

I realized at that moment how strong this boat actually is.The other huge gift from above: not one drop of water ever went below, which would have been a disaster. Now I keep her in the driveway of my current home, under a covered frame, so I don't have to worry again. *Miracles DO happen.* On Tue, Apr 16, 2019, 1:56 PM Alex Conley <conley.alex(a)gmail.com <mailto:conley.alex@gmail.com>> wrote: > Thanks Jerry- knowing the hump is separate from the keel cavity eliminates > all my worries.

M23 cushions

Thanks to all for input. I did get custom ones made out of sunbrella, will try to post a photo in the photo area. As for fastening, right now I had the seamster sew a piece of fabric that extends into the port and stbd lazarettes which grab the cushion and prevents from slipping in extreme heeling. It seems to work well. Best all. Theo
