Moisture around porthole windows - Misdirection - 11-10-2021

I've read about the boatdry system, never had a need for it.

I was able to reuse 5 out of 6 gaskets last time I did mine, but I knew #6 needed replaced before I started.

I also was told by the surveyor that the readings around port side portal forward was a little high. Seems like common issue. I'll look for the you tube vids and take a crack at it in the spring.

For the moisture around the anchor locker, you can drill a sparse matrix of 1/4” holes on the underside of the laminate without compromising the structure. Then over time (years) the area will dry out.

For the wet foam under the port light, I assume you mean the cabin trim not the hull laminate. Yes, you can let that dry out.

When rebedding the port light frames, I do NOT recommend using 3M 4000UV. Over time, it simply disappears. I’d probably now use 3M marine silicone after cleaning all surfaces with acetone.

I am wondering how much silicon I should use on the port hole frame when installing a new gasket? Does one put a small bead around the track jusr so it will stick or a larger bead spread around to cover the entire track's area?

I have the recommended Dow 732 silicon.

I bought some caulk/silicon remover spray at ACE Hardware that is to remove it in pieces rather than dissolve the old silicon. Anything work better?

When removing and cleaning up the old silicon, paint thinner worked really good.

I was very generous with the bead, and cleaned up the excess.

I just got new seals/screens from Tiara and they sent an entire tube (squeeze tube, not caulk gun size) for each porthole. So I’m presuming they want a good bit on each.

Did your kit have seals and screens or were the screens embedded in the seals?

My kit from GG Schmitt came with the gasket and screen as separate pieces.
