ShipCrafter makes sinking a design problem before it is a combat problem

Before ShipCrafter asks whether your vessel wins a battle, it asks whether the vessel you built belongs above the water. The developer’s description ties buoyancy to weight and submerged volume, and says the editor displays density and center of mass. Those readouts put a physical consequence beside the urge to add another part.

An imagined redesign makes the distinction useful: adding equipment changes the construction you are evaluating, so its military purpose is only one question to ask. You also need to inspect what you have built as a floating body. The listing does not supply a rule of thumb that makes every heavier or larger design better.

Adjustable ballasts extend the same subject to advertised submarine designs. They are a particularly clear reason to investigate these tools: controlling immersion is part of construction, not merely an accident suffered during combat. ShipCrafter’s promise is not that your elaborate ship will work. It is that the editor gives you physical properties to reason about before finding out.
