Re: false keel

Thank you for the advise. It gives me confidence to continue. I decided to have a look at the plugged hole through the starboard side of the keel (The one to the left of the peel ply in a previous image). As I sanded off the bottom paint the plug began to leak around its edge. A little poking, hamme...

Re: false keel

The newly discovered holes/dowels derailed my glassing plans. Since I'm a peel ply virgin I went with plan B and did a peel ply test. My layup schedule is to level the bottom, glass over the rudder shoe area, add the 1 inch thick bottom layer you suggested, glass my way up the sides and finally glas...

Re: false keel

The rebuild begins with some thickened epoxy and peel ply over the grooves in the lower gudgeon resin block to prep it for glass. You can see in the image three plugged holes approximately 1/4 inch in diameter. They were drilled through the keel by the previous owner and filled with wooden dowels. I...

Re: false keel

The good news is that sanding the bottom roving with 120 grit removed what I thought were cracks. It seems the "cracks" were print-through from the cracks in the resin just removed.

Re: false keel

Thanks. I will rebuild as you suggest with thickened resin. The old resin layer does not seem to have been thickened. Perhaps the new thickened resin layer can also be strengthened by mixing in some chopped glass to prevent it from cracking.

Re: false keel

While prepping the bilge for glassing where the the rudder shoe pierced the hull, the bottom of the bilge needed to be sanded. Under the top two layers of mat was an inch thick layer of cracked resin. Chunks could easily be popped of with a screw driver. Underneath was the actual bottom. So, my boat...

Re: false keel

In the previous image, the dark bands in the resin below stern tube opening indicate delamination. I got a new toy and continued to remove this damaged resin. Finally I ended up removing it all. The fact that you can see woven roving most of the way around the stern tube opening indicates that the t...

Re: false keel

I decided to go ahead and grind out the stern tube bore voids (and delamination) since they essentially drain to the bilge. You can see the roven woving on the starboard side of the stern tube and in the image without the tube where the glass just popped off indicating that the starboard side of the...

Re: false keel

By the way, some of the voids in the stern tube bore had water in them. FYI here is the die grinder I used to remove the stern tube. The flapper drum began its life with a two inch diameter but prior use has worn it into this spherical shape. This shape was good for enlarging the 1.5 inch ID of the ...

Re: false keel

I ended up replacing the stern tube. I used a router and a 60 grit flap sanding drum on a die grinder to remove the old tube, after first cutting off the exposed portions with a multitool. Since the stern tube is perpendicular to the deadwood, I freehanded a router to remove the first inch of the tu...

Re: false keel

Thanks for the reply. The stern tube is solid glass. Is was turned down on the inboard end to accept a dripless seal, making it look like two pieces. Yes I plan to reuse the yanmar inboard. I will post a shot of the exterior portion of the stern tube when I get back to take boat.

Re: false keel

Anyone know if these cracks are serious? They are on the starboard bilge wall and bottom of the bilge but not the port side. They seem to be superficial since they don't continue though the taper I ground in the glass on top of the ballast. PXL_20210705_000409294 (1).jpg PXL_20210705_003728866 (1) (...

Re: false keel

As I was grinding a taper in the glass joint where the surface of the false bilge was glassed to the starborad side of the boat, I noticed that a screwdriver slid easily under the glass. A little pressure popped off a big chunk revealing the same roven mat as lower down in the bilge. PXL_20210701_21...

Hi Ron. Here are the pictures. I measured the thickness to be approximately 4 inches from the rudder shaft groove to the interior and the same from the bottom of the keel to the interior. The hole I put in my keel lets you see the inside and outside at the same time. Not good for keeping water out o...

Re: false keel

Hi Ron. If your new rudder shoe bolts up through the bottom of the keel, like on an Alberg 30, you are in luck! This area is very strong and three to four inches thick at least it is on my Triton. My rudder shoe bolts on from the side of the keel and I removed most of the glass under the shoe making...

For the past few days, fresh water has been seeping from the foam around the lead ballast into the aft end of the keel where I want to glass. Any ideas on how to speed up the drying process?

Re: false keel

Thanks for the comments. Glassing over the resin globs sounds right. However I had to figure out a way to prep them as they were covered by what I call peanut brittle. The peanut brittle is formed when the foam adhears to the resin. You can pry it off with a screw driver but it's tough. The resin gl...

Re: false keel

By the way, the foam smells strongly of diesel which must have entered the false bilge through its many surface cracks. The top of which seems to be pure resin. I am leaning towards removing the false bilge entirely, glassing as necessary to strengthen the shoe area, not filling the space with anyth...

Re: false keel

The ballast lifting u-bolts protrude through the glass in the forward bilge. So my Triton is definitely internally ballasted. I suspect the foam was factory installed during layup since I can't see any tabbing on the false bilge bottom.
