Design: AS-SPB2-Crystalclad [3, 5, 3]
The Crystalclad is based heavily off of our existing steamships. The most notable change is that it's now almost entirely made out of crystal, featuring our most ambitious design yet. The crystal hull is smooth and sloping, dictated by a complicated curve formula that occupies the majority of the crystalworks circuit for the design, but allows the ship to cut through water just as easily as our existing ships. Because of the difficulty combining crystal with wood or steel, the majority of the ship is just smooth crystal with the occasional eyehole to mount hammocks, furniture, ropes, equipment, and the two steam engines that power the ship itself. This has a tendency to make the floors slick, especially when wet.
The steam engine setup is pretty much just copied from the SPB1 Fog-O-War, being two steam engines hooked up to a four-blade paddle on the rear. The armament has been upgraded, allowing either three HC1-E's or a single HA1 to be mounted above-deck. Because shooting beyond line of sight is less helpful on the high seas and requires three apprentices to fire, the Crystalclad design instead features three HC1-E's that can all be fired by a single apprentice by themselves, as the higher firerate is more beneficial despite the decreased lethality of the individual cannons. Thanks to the increased number of apprentices we have at our disposal, each ship features two apprentices; one to operate the steam engines, and the second to fire off the cannons.
It is relatively wide-berthed, allowing a decent amount of troops or cargo to be transported much in the way our current longships do. The crystal is slightly heavier than wood (but not as heavy as steel), and though it is now fire resistant the ship is no faster than the Fog-O-War.
The steam engines generate a fair bit of vibration, which is a significant problem. After a few days, microfractures begin appearing in the steam engine mounting and require magical maintenance to prevent cracking. Even more problematic is the fact that being made of crystal changes the center of gravity on the ship, and rolling seas have a tendency to capsize the ship.
Over all, the ship should be more resilient to damage without sacrificing speed, and has a higher damage output to boot. The fact that the ship is primarily made out of crystal means it's merely Expensive.
