FG patches in forward portion of hull ???

On the internet, I am looking at the chain locker area of a C-22, and I note a series of patches in the fiberglass just below the hull/deck joint.

The patches are located in a position that they seem as if they are part of the backing for the rub rail.

My question is, "is this factory work?" It seems different than the hull penetrations and backing for the stantions and the windlass.

Can anyone tell me what I am looking at?

Thanks!
 
I think what you are seeing is the "coverage" of the joint rivets. I believe they are where the deck and hull come together, and also hold the rubrail in place. Those, (if I am looking at what you are), are factory. I know I have the same thing in my boat, and have seen that in others.

I believe Harvey is right. Those small lumps cover the back of the rivets that hold the rub rail on. On my older boat the rivets where exposed on the inside and appear to have been covered with 5200 or similar. Without the covering the rivets would leak. The hull/deck joint is fiberglassed together in the normal manner.
 
Thanks, guys.

It just struck me as strange that the rivets are covered with an unfinished FG glop, whereas the thru-cabin fittings (presumably for the stanchions and windlass) are backed with stainless hardware.

It had not occurred to me that the hull-deck joint overlaps, and rivets are fastening more than just the rubrail to the hull.

Got it now, and am feeling much smarter.

Thanks! :thup
 
The hull to deck joint is glassed on the inside, before the rub rail is put in place or the interior finish is applied. After the rub rail is put in place, and the rivets are set--the inside of the rivet is covered with some material, and then finish applied. These rivets are not structural, as they are in some boat where there is a "shoe box" overlap of the hull to deck joint. The glassed joint is far stronger than a boat where there are rivets holding the hull to deck joint.

So the rivets are only holding the rub rail extrusion in place, as you first surmised. There is no need for a backing plate, since this is not structural.
