So back to the original game plan. Bevel each hole, where possible, 12:1 and lay up multiple layers of glass with some 404. Will 410 afterwards. Still considering the sleeve method.

Oh and I will remove that "Back Plate Spacer" to inspect the screw holes and fill with epoxy.

The biggest issue will be low crawling into the back to set up a backer so the epoxy will not free-flow. AND the weather. Suppose to snow/rain for a week.

Hmmm... here's an idea... What size is your bolting? There is braided fiberglass tubing that you could sleeve the holes with. That would have the best chance of bonding to the hull and creating a seal. Go slightly oversized on the id, wax your bolts, fill the holes with thickened epoxy, and support the rudder during assembly to get everything aligned properly.

Sounds easy 😄

McMaster is great if you need it tomorrow and don't have time to search for another source, But they are very expensive.

I am searching for fiberglass tubing for a different project and found this source: https://mgs4u.com/product/1-od-round-tube/

They offer similar pultruded fiberglass tubing, 1" OD x 3/4" ID in pre-cut lengths of 6", 23-1/4", 48-1/2", and 93". Shipping on the 6" or 23-1/4" pieces should be more reasonable, even to Alaska. The 23-1/4" piece is $6.30 and for reference, they offer shipping to Anchorage is $17.95.

Yes so much better with S/H. I need to head down and measure. The 6" version may be the ticket. Now for the weather to warm up to above freezing. Thanks for the research. It's one less thing to do.

NOW to purchase 1000-ft of Line to replace ALL of the running rigging. $190 to ship 4 (300-ft) spools to Alaska. Not too bad.

Today I THREW some 404 slop over the holes as a temporary solution to keep rain out. Will not get to the actual fix till spring.

I also had a coworker fly his drone to get some mast head views. Looks like my main had a "rub spot" that will need attention also this spring.
