Lots of us have rudders that are less than perfectly water tight. Many people 
either drill a hole in the bottom so it can drain,
and patch it every spring, or install a permanent drain plug. The main worry is 
to not let the water freeze in there.

There is a C&C 38 at a marina here that was discovered upon haul out to have 
dropped one half of the rudder skin in the water. The
exact time or place that this occurred is unknown, and the boat has sat for 
over a year now while the owner contemplates his next
move. Water freezing over the winter is suspected to have played a role, but 
the particular nature of the damage is due to the
fact that the rudder construction included two half skins that were glued 
together. The rudder on my 27 seems to be constructed in
the same fashion, and water drips out of a crack in the seam every fall. The 
water eventually stops dripping, so I figure that it
is self draining, but I have often wondered if it wouldn't be better to "skin" 
the rudder seam with fibreglass matt and try to
fair it smooth afterward. Seeing that 38 sitting there with half a rudder has 
made me think more seriously about preventative
measures but I have not done anything about it so far.

Subject: Stus-List Rudder Damage and possible blister


Upon haul out a week ago I noticed a prior repair that was made to the
rudder but has now given way. I don't know how I missed it on purchase
but there was brand new bottom paint which must have concealed it
enough. In any case it is now mine to deal with. It seemed to weep water
for a few days and had the copper (or what looks like it) from the VC17
coming out. Most likely this is rust though.I have a link to the photos.

Using Google I found a few hits with some similar repairs and horror
stories. I am ASSuming that it is fiberglass over foam. The foam is
probably soaked and I was considering drilling some small holes near the
bottom to see what drains out. I guess the real concern is not fixing
the area it is what damage may have occurred from water being in there
and corroding the post.

In addition I found 2 other small areas that look like they were
repaired on the hull but now the repair looks to have degraded. I don't
have enough experience to know what a blister looks like but there is a
picture of this too.

I have hammered all around the areas of both the rudder and the hull and
everything seems sound. I think the rudder is toast. What may be my
options for this. And of course the blister.
