Ch. 1183Warship Designer
Joseph proposed using iron ribs to strengthen a Steam Warship’s defenses, and Sane explained how sacrificial Zinc anodes could prevent the iron from rusting. The discovery led Sane to suggest further iron components, until Joseph learned that the ship’s supposedly Copper bottom plating was actually Brass.
- Sane told Joseph that iron armor thick enough to stop cannonballs would weigh too much for a Fourth-rate Ship, and Joseph asked how much additional load the new ship could carry.
- Joseph realized iron ribs could reinforce much of the hull and learned from Sane that replacing the wooden ribs would add about 15 tons.
- Sane warned that seawater would corrode iron ribs, and Joseph proposed attaching Zinc Sacrificial Anodes to protect them.
- Sane embraced the idea and suggested replacing the Intercostal Beams and ship-bottom Rivets with iron to improve defenses and speed construction.
- Joseph discovered that the Rivets and the ship’s supposedly Copper bottom plating were both made of Brass.
