Two related issues:

 

1)      I found an uncharted rock at low tide this summer so am now having a
mast out/keel off repair by a reputable yard near Sidney, BC. Since my draft
is slightly more than the 2 meters Canadian Hydrographic set as their
minimum for charting obstructions I guess they are off the hook.

2)      However – the keel has shown minor weeping from a spot on the port
side corresponding to about the lower end of a keel bolt - seen at haul outs
since purchase  about 6 years ago. At least two surveyors have seen it and
ignored it. Usually there is a teaspoon or two of water and a bit of rust
seeps out over 24 hours or so. This time there are two spots.  While
removing the keel (as per #1 above) light grinding over the area shows a
fine vertical crack a couple of inches long and a couple more smaller cracks
on other spots further back in line with bolts.  On this thin keel the aft
bolt is only about ½” diameter. I had been told earlier at a Rendevous that
the trickle, etc could be caused by impurities in the scrap lead used by
Mars originally. At purchase and since then there has been noted a very
slight cant to starboard over the whole keel (maybe ¾” at most) again noted
but ignored at surveys.

The yard is telling me several things and I am interested to know if anyone
else with this keel has seen similar issues. Among the suggestions I have
heard by the yard so far: do light grinding of the area then prep and patch
with mat/epoxy to seal; or do the patch and also an overlay of fibreglass to
give more strength (neither of which would be guaranteed); or consider a new
keel(!). They seem certain the cracking is stress on the keel compounded by
annual hauling at our Club marine railway for yearly bottom prep, etc;
they’ve also indicated they would contact Mars for advice. My concern is
that none of the suggestions sound like a final solution if they are correct
in the analysis and reasoning.  There are also concerns re crevice corrosion
in the long term in any event.

 

So: If anyone has heard of and or dealt similar issues I’d appreciate
feedback. I hope to contact Rob at Southshore as he had the original
information that scrap lead used in that era was the culprit and essentially
a cosmetic issue.

 

Thanks folks. List advice is a great asset.
