[C38] Stanchions

This type of fitting is used by: C&C, Hunter, PDQ, Bayfield, and
Freedom yachts. I think the footprint is the entire toerail, which is
significantly stronger than our pad fastened to a plywood deck.... If
I was to worry about strength, it would be the shear force exerted on
the bolts if the toerail stanchion base is not a good fit with our
toerail... I would weld the stanchion to the base rather than rely on
the throughbolt. I can also comment on the strength of at least the C&C
toerail as I have raced these boats and that means bounced a time or two
off the lines and stanchions! Have crewed Hunters as well, but don't
remember the stanchion design.
I think my next step will be to contact Garhauer as they are reputed to
have first made our toerail. I also could easily fabricate my own bases
that would incorporate Ander's ideas.
But, will it look pretty?
