That's a good Idea, much eaiser than trying to glass it in. Thanks for that idea Robbin.

I do not remember having to take it out to drop the board but if you epoxy the holes you could use a good bit of silica additive to make removing the epoxy by drilling out easier. But I see no reason not to epoxy it in. Robbin Jim Ellsworth wrote:
Ok another issue:
This started during my San Juan trip in June. When I pulled the boat out at the end of my 15 day trip the centerboard pin was almost all the way out. I have tried putting a coat of 5200 over the holes but the pin keeps pushing through the 5200. I know Sean ground out around the pin area and glassed over the holes. Has anyone else had this issue and how did you solve it.
Thanks!

Another Option,
I want to have an adjustable traveler also but don't want to change the track. I found something on the Schaefer web site. I think the track is a Schaefer 1" and on their web site I found a Spinnaker Pole Slider Towable/lined part #17-78. This is a car that would fit on the existing tract with a ring to connect the mainsheet and two u rings on either side to put a single or double block so you can run your lines from an eye strap then through the blocks and to a cam cleat mounted to the cockpit seat wall. I am not sure it is any less expensive than the Harken option but it could be done without drilling more holes in the cockpit floor.

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 cockpit. I'm surprised the glass separated from the plywood by squeezing too tightly on the bolts; you must have cranked them down
hard enough to compress the wood. I will have to get the boat on the water to experiment with the track 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. Tom Jenkins M17 #626

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.

I am plotting installation of a Harken windward sheeting car

on my 2004 M17, in place of the factory T track and slide. Anybody
know
what the present track is screwed into, so I will know what to expect when
I install the 7/8" CB track? Additionally, the new track is bolted on
3-15/16"
centers (obviously 10 centimeters), but I measured my old track
at 4"
centers. Is the old track metric as well, and my measurement faulty? (My boat is many miles away at the moment, so I can't remeasure). Thanks in advance for any insights and assistance.
