I was looking thorough regulatory filings on a company which owns some
tugboats in Freeport in the Bahamas and read that these tugboats have a
life expectancy of 5 years. That seems a bit short, esepcially after all
the hassle I've got in this newsgroup over using exterior grade plywood
with a life expectancy of maybe 10 years.

My 65 foot wooden tugboat, the F.L. Fulton, is 60 years old and doing
just fine.

As a working tugboat it is, however, very much noncompetitive.
