[Rhodes22-list] Biological Centerboard Fouling/Jamming - A SeriousIssue?

[Ben Schultz]

I had Velvet Elvis pulled out of the water for new paint this summer.  It
had sat in brackish water that tends to grow a whole lot of slime on
whatever's in it for a week or two -- especially in summer.

I hadn't ever had it out of the water in the (almost) four years since Elton
left it with me.  I expected a real mess under there, but there was just the
smallest layer of slime, which the pressure washer took right off.  It
almost looked like it didn't need new paint.

I've got to think that it would take a really, really long time to get
enough fouling to jam the centerboard.  However, if the boat just sits in
its slip and never gets sailed, maybe that would speed up the rate that the
crud builds up.

Anybody sailing this weekend?  I think I'm going, weather permitting.

Thanks for bringing this up Roger. You might recall that my centerboard was 
stuck in the trunk last summer, and it took quite a bit of effort to scrape 
out all of the fouling mass in order to get it to lower. Most of the 
fouling organisms were gooseneck barnacles (Balanus sp.), oyster spat 
(Crassostrea virginica), and Bryozoans. This fouling resulted under the 
previous owners watch, so I cannot comment on the time it took to achieve 
the condition. I was unaware of it as the boat sat on a trailer during it's 
overhaul, and the centerboard was not able to be accessed from the outside. 
I never did pull off the CB Cap.

Within the next several weeks (time permitting) I plan to lay the boat over 
in the clear water near the island and assess the condition again. I will 
take some pictures with the Nikonos and post them (if it's possible to get 
a view in there), along with any commentary. I haven't done any maintenance 
to this area since July, and don't plan to haul the boat till deep winter 
(maybe around March) in order to bottom paint. Currently the CB is 
partially down, I have not exercised it in awhile (other than plowing over 
a few shoals).
