Re: M_Boats: Centerboard Pin Problem

27 Feb 2010


      John,
Just wondering if the pin is bonded to the board and rotates in a  
sleeve, or if the pin is supposed to be immobile, and the board  
rotates on the pin.
Thanks,
Tom Jenkins

I had the same problem for awhile with my M17.  I would check the  
pin when I stopped for gas and sometimes would find the pin hanging  
part way out.  It looked like when the boat was on the trailer the  
cb was being pushed up a bit into the trunk which took the weight  
off the pin which was then allowed to rattle loose with  
vibrations.  The first time I saw the problem was at a gas station   
halfway through a long trip.  For a stop-gap measure, I taped over  
both holes and it worked for the rest of that trip.  When back home  
I had  both sides epoxied and that seems to have stopped the problem.

Trailering my M15 up and down the East coast I became convinced  
that trailing
vibration is what moves the pin out.
I tried 5200 as well and did not check it after a long tow.  Lost  
the board
entirely 15 miles offshore (1/2 way to Nantucket from Hyannis, MA.   
It's a good
thing that the M15 sails reasonably well without the board.
It turns out my pin was not original and was slighty longer than  
the one from
the factory.  I ground mine down about1/8 inch and used epoxy to  
seal it.
I have not had a problem since.
Thanks

Good Advice Joe,
After spreading some 5200 over the hole and having it poke through,  
I put a
second coat on and only put the centerboard down sailing upwind.  
This seemed
to work until I noticed the pin hanging out after my trip to Havasu  
(6 hr.
drive + 3 days in the water).

I saw something not too long ago that cautioned keel/cb owners to  
never,
never anchor/moor with the cb in the down position for this reason.

Hi Gary!
I think in the San Juan's it was sitting in the slip/anchor/dock  
that
worked
it loose, but good point you bring up about the trailer to be  
honest I
don't
think I have inspected it prior to launching after a long drive.
At any rate I think I will probably grind out a little  
indentation and
fill
with some matt and glass as Sean did.

Jim:
Vince and Sharon Himsl had that pin problem on their M15 and  
knurled the
pin
and I think glued it in. I haven't had the problem but am  
wondering if one
might best lower the board down onto the trailer (and re-cleat)  
so that
the
board doesn't rattle around as much during the trailering. That  
should
reduce the motion that tends to work the pin out. I did calk over  
my pin
the
help assure it won't come out.

Another Option,

track. I found something on the Schaefer web site. I think the

a

I am not sure it is any less expensive than the Harken option but it

Tom,

When I relocated the mainsheet track, I put it about 18" back from  
the

companionway. That location has worked out real well.  If you do move

your mainsheet track very far, you'll need to also move the boom  
bail,

but that's easy enough to do. If your worried about drilling extra  
holes

in your boom, just take a look at Gary O's boom. :-)  I would also

recommend doing the epoxy plug thing when you put new holes in the
...
cockpit sole. That will keep moisture from getting into the wood  
core,
...
and also prevent the compression problem.

Hi Randy,

Thanks for the tips and cautions.  I did not know the track was

through-bolted, since I have never stuck my head up under the

hard enough to compress the wood.

I will have to get the boat on the water to experiment with the

location, but the water is still quite hard in our neck of the

woods.  It would be nice to be able to sneak between the sheet and

the tiller to tack without raising the latter (I now have less than
...

an inch clearance), so perhaps I will get two upgrades in one.

Hi Tom,
...
...
...
...
...
...
I can help with some information having done the same on our 1988
...
...
...
model. The cockpit floor is comprised of a
...
...
...
fiberglass-plywood-fiberglass sandwich. The top layer of
...
...
fiberglass is
...
...
...
as you can see in the cockpit floor with non-skid, and roughly
...
...
3/16
...
...
...
thick. If you were to crawl under your cockpit and look up at the
...
...
...
bottom of the floor you would also see fiberglass but this is mat
...
...
and
...
...
...
resin. Between the two is plywood. My guess is the total thickness
...
...
of
...
...
...
the sandwich is just less than 1".
...
...
...
...
...
...
Tightening the new track caused the top layer of non-skid
...
...
fiberglass
...
...
...
to separate from the plywood core on our boat (I heard of the
...
...
same
...
...
...
thing on one other boat). Jerry recommended a vacuum technique to
...
...
...
re-bond the two. Jerry made it sound easy but I concluded it was a
...
...
bit
...
...
...
over my head. The separated area formed a bubble in the forward
...
...
floor
...
...
...
of the cockpit. I drilled a small hole through the top layer and
...
...
by
...
...
...
tilting the boat a bit was able to manage a sufficient quantity
...
...
of
...
...
...
penetrating epoxy into the detached area. I then placed several
...
...
cinder
...
...
...
blocks on top the floor while it cured. Turned out OK! Lesson
...
...
learned
...
...
...
is to not over tighten the screws holding the track. They are
...
...
machine
...
...
...
thread and fender washer and locknut'd on the bottom side. Snub
...
...
with
...
...
...
some bedding compound and you are good-to-go!
...
...
...
...
...
...
Yes, the holes between the two tracks don't line up. Larry took
...
...
the
...
...
...
opportunity when mounting his new track to move the track forward
...
...
...
about 12 inches or so. This still allowed for a person to sit
...
...
forward
...
...
...
of the track but gave the helmsman more room to move between the
...
...
...
mainsheet and tiller. Because of the change in mechanical
...
...
advantage by
...
...
...
moving the mainsheet forward he also upgraded to a 4-to-1
...
...
purchase.
...
...
...
The windward sheeting setup is a nice package and has worked
...
...
great.
