Yellow/brown spots all over the boat

Merrymeeting · 06-06-2016, 07:58 PM

Believe it or not, insect and spider egg casings. They are amazingly durable and annoying!

No, I know what spider droppings and egg casings look like. This is more like ever water spot on the boat turned into a brown/yellow stain.

It's definitely not an insect byproduct of any type.

This mystery was solved once before. Ballistic (or Artillery) Fungus.....perhaps some yellow by collecting pollen. Don't park near bark mulch. Some interesting YouTube slow motion vids of it in action if you search.

I would NOT use acetone on fiberglass. Try Mr. Clean Magic Eraser. If it doesn't work on that problem, you can always use it on boat upholstery.

It DOES Work. I use it at home on my latex painted walls and enamel trim. Can't explain why it works. Try It.

Thanks for this link, I'll have to check and see, I don't see any wood chips near my dock and my boat is about 80 or more feet from shore as the dock juts out into the water.

It's possible the wind too it, but these don't look like black spots, more like a yellow/brownish tiny splotch, as a water drop may make.

I'll try to take a picture the next time I'm on the boat.

Luckily a bleach solution seemed to clean remove it from the raw (un waxed) gel coat. I think it would wash off from waxed gel coat.

I asked here thinking that others may have experienced this last weekend. I hope it doesn't return this weekend!

Are the spots totally flat? If you close your eyes and rub your finger over them, can you feel them?

Rich · 06-08-2016, 08:09 AM

If I remember, they feel no different than a water spot would feel, maybe a bit of a sensation of roughness, but nothing protruding.

I have to get a picture so you can see it. I'll try to get a shot on top of my radar arch, I hadn't cleaned that area yet.

Yes, I had the same spots on my boat as well as many other friends of mine. Your not the only one. They are very tiny and its not from the yellow pollen I don't think because they are a different color, brownish orange and theres been yellow pollen every year and never seen these spots before. I am not using 50/50 bleach as that would still be alot of work and would undo the expensive professional detailing I paid for this spring. Will see what happens.

Just got this link from the UNH Extension Service. As someone mentioned in an earlier post, most likely some type of bark mulch fungus.
