As an aside: US boats used lignum vitae wood for the shaft seals; they were shaped like truncated cones. I believe lignum vitae was also called ironwood. When in drydock the seals had to have water run on them to keep them from drying out.

I wonder what modern boats use? Some sort of exotic synthetic, I would think.
