Okay, you asked for it....
1) Porthole and spacer. The P323 cabin wall thickness is 1/4"-1/2", so a teak spacer is required. And before I get flamed, this is layer 1 of about 6 of the varnish on the spacer! Also note that the teak spacers needed to be trimmed to fit, as there is not sufficient height for them to be installed otherwise. Easy job - some measuring, a few minutes with a plane.
2) As in other projects, there is a void between the liner and the deck, which IMHO needs to be filled. I opted for fiberglass cloth and thickened epoxy.
3) This gives you some idea of how they look installed
4) And an exterior view. I expect the exterior to go green fairly quickly; I intend to keep the interior shiny.
