ruise ships built in the Aker yards in Finland have at least 4" thick
teak decks. (I've seen photos). They probably sand them down every
year with a floor sander. Never have to replace them during the life
of the ship with that much thickness.

US battleships were built with four inch thick teak decks.In the case
of the cruise ships, I had thought the teak was supposed to be good
for the life of the ship. If they never sanded it, it would last
forever, and not just forever for all practical purposes.
