From Fred (a bad mutha-SHUT YO MOUTH) on the subject of Meerschaum and forum member:
"The term 'Navy', as used in the tobacco industry, started back in the days of
wind driven ships. Sailors preferred Plugs and Rope cuts of the blends they
smoked, since they were able to carry them on their person, not having to rely
on finding a hiding place for them, and they could carry more tobacco with these
cuts as well. The term is still in use today, but the definition has become fuzzy
with the broad use of the term by blenders. It can now mean: Rope, Plug, Flake,
Spun Cut and Coin cut, with about any blend type known. The use of Rum to keep
Sailor's tobacco from drying out resulted in the Cavendish process used today
by blenders, who have more resource available to them than just wrapping the tobacco
up in a bit of sail cloth"
