Looking back in time and considering all a wooden ship must do to survive a voyage at sea, it seems like the risk of Fire is practically insurmountable.
Surging waves, raging storms, and fires lit by whale oil aboard a ship constructed of pure kindling. While I know that lamps were tied down and secured, and surely the lights would need to be put out in a raging storm, but surely unforeseen circumstances were pretty common on an ocean voyage, especially at night.
Perhaps it's a ridiculous question since the knowledge would've sunk with the ship, but do we have any estimation of approximately what percentage wooden ships might have been lost to a Navy due to fire mishaps in times of peace?
