I have a sketch already
traced, and even have a spare copy. Should I send it to you in care of Bob at
Nor’Sea, or would you prefer another address?

About a month ago I inquired on
this list if there was an interest in a new centerboard for the "old" M-17,
and got quite a bit of interest; looks like enuff to ppursue the
matter.
Interest was divided between a bronze board and a lead-filled
glass board. There is no bronze foundery around here and after a quick
search the closest one is in the Los Angeles area, which would mean shipping
the boaards to here (Sacramento), where I would grind and drill them, then
ship them to the customer. The cost would be in excess of a thousand
dollars, which seems like a lot to me. A glass board with a cast lead
core would be lighter (120 lbs???) and there is no good, simple way I can
think of to mold in the tang which stops the board from overdropping so it
would have to be supported from the hoisting line, which PROBABLY wouldn't
be a problem considering the lesser weight of the board. The good side
is that the board should be less than half the cost of a bronze
one.
Something to consider is that several (many?) of the older 17's
have a problem of swelling cb trunks, probably due to water getting in and
causing rust. I could help this problem by making the board about 3/4"
thick instead of the original 7/8". Owners of boats not having this
problem- hopefullly the great majority- could shim the boards around the
pivot hole (a simple matter).
If I do this project
it will be either in mid-summer, when I am finished with the 23 project at
Nor' Sea, or next fall sometime. Also, I need an accurate paper
pattern of a board as I have no good measurements. The original
foundry pattern disappeared during the bankruptcy of the iron foundry that
had made the boards for many years. So if one of you pulls your cb in
the next few months, please lay it on paper (newspaper is fine) and trace
around it with a marker pen, not forgetting the pivot
hole.
