Does a firemast count as a regular mast?
No, a firemast is not the same as a standard mast. It has no cannon (it cannot shoot), it does not count for ramming, boarding, or terrain rolls, it cannot be removed when the ship is hit or would have a mast removed/replaced, and it does not block lines of fire. The exception to this is that a ship with only firemasts may still be given move actions normally, even though it has no standard masts remaining.
