How long does it take for barnacles to
cling to the hull of a boat?I've looked at
a Whaler with some barnacles on the hull.
Could I scrap them off then buff the
remaining shells without damaging the
gelcoat? There is no bottom paint on
the hull.They said the boat only sat in the
water for 2 weeks.
Thanks,Ed Stone

Ed, I would also be curious about the answer. I noticed that even after two days in the water in a creek of the chesapeake bay I start seeing barnacles form - although they come off by rubbing quickly. I wondered as well if keeping a boat in the water for a weekend and then having the scrub the bottom to removed scum and starting barnacles is still better than painting. Or do people paint the bottem if the boat is kept in the water for any length of time. Paul

Hey Paul,
I did find out how to remove them.They sell
products to help remove them,but you can
use diluted muratic acid along with a
brush and scrapper.Do small areas at a
time and brush on the diluted acid and
then scrap them off with your scrapper.
(scrapper made out of a small piece of
plexi glass ground sharp on one end)
After completed polish or buff with a good
wax.(that is what I was told)
good luck,
Ed Stone

My experience has been that once the barnacle has attached itself, there will be a small pock mark in your gelcoat that only sanding will remove. My Montauk has a very rough bottom even though I have tried various ways to smooth it. Only real solution here is prevention.
