Coaming #coaming questions #coaming

 

Hi All
what is the easiest way to remove the rivets from a coaming without breaking it?

Thanks,?

Andy
 

Depending on the age of the boat, the coaming is attached with rivnuts, screws that go into a rivet-like base. If there's no screw slots, you have regular rivets, which can be carefully drilled-out. I use a spade bit or a conical bit and press lightly to erode just enough of the center of the rivet to detach it from the shank.

Hi Andy,
Why are you removing the coaming? I removed mine when I painted the deck and wished I hadn’t! I was able to reattach it once I ordered the proper rivets, but rivnuts (which I had on my boat) couldn’t be reattached, nor could screws and nuts because the floatation blocks are in the way of the majority of the holes.
 

I don't know Andy's reasons but for me, the coaming had a small chunk missing from the previous owner dropping the mast on it in transport, and the front side of it had been improperly glassed originally - glass mat very visible - and looked un-finished and looked really ugly that way, so I just unscrewed it. The rivnut bases stay in place when you unscrew the screws - at least, they did on mine. The screws were a little tight from dirt, not so much corrosion, since this was a freshwater boat and the original hardware was stainless. Took some penetrating oil and patience to get some out. Worth it, though. The coaming is an expensive part to replace and to ship. I filled the missing chunk with marine tex and filled in the rough glass front with Bondo filler, sanded then spray painted it with a rattle-can of Rustoleum that was a perfect match to the footwell color. Went back into place with screws and some sealant just to make extra sure, and it looked a hundred times better.

Hi All
part of coaming had become dislodged ?from the boat and I wanted to fix it by replacing the rivets ?

Thank you for the help?
 

Yes. The Rustoleum colors are a perfect match for everyone that I've painted. It really makes the boat stand out when you take the time to do it right.

Depends on whether you have the pop rivets or rivet nuts with machine screws. Pop rivets drilled out with a 1/4 inch steel bit. Machine screws as mark mentioned.?
