[C38] Keel & Toe Rail

[Don Strong]

Mark:
Chuck's solution to the toe rail is very cool. I will use it on my toe rail.
Last haul out I had weeping from several spots on the keel. The yard 
suggested grinding away the spots, filling, then faring them. They said 
that the infiltration would spread. I had them do the work; they charged 
about 1 boat unit for the job. I am three years into this bottom job, 
and the diver does not indicate any problem down there. Of course, next 
haul out will reveal all.
