Stantions, Stern Railing and angle of the dangle

[Blue Stocking]

For the deck wedges I cut the base plate shape + 1/4" all 4 sides from a piece of 5/8" kitchen cutting board, taped it to the deck, and poured slightly thickened epoxy into the mold. It will self-level if not too thick. Use slow hardener to limit the exothermic reaction.
No leaks on a boat that is normally described as a "Cheoy Leaky"

I'd feel safe at that rail, Mark

Looks like your boat lives in a good neighborhood

Blue Stocking, so your using the cutting board material as a mold to hold the epoxy in shape as it finds its level, sets up and then remove the cutting board mold?

Yes--I actually made 4 molds to save time. The self levelling takes care of the changing deck curvature. Work it a bit to help it level flow.
Depending on ambient temperature, you may have to play with the amount of powder in the resin.
On my first attempt I added too much microballoons, and the mix swelled and mis-shaped.
Duct tape held the molds down tight enough to stop thickened resin leakage.
I then countersunk the wedge top, inserted the bolts thru the plate, and made a collar around the bolt on the baseplate with sealer. 3M 101.
When you pull down on the bolts, the sealer compresses into a "O"ring, which is forgiving of movement forces on the stanchion.

Me too.

That photo was taken before shipment while in Baijiao, Zhuhai, upriver from Hong Kong. Boat is presently in Vallejo, CA marina:
