High Seas

High Seas is a NeoForge mod that adds a physically simulated flooding and buoyancy system for large ships built with Create Aeronautics.

For best physical behavior, it is recommended to build vessels with a completely enclosed volume.

Instead of using simplified "boat physics", the mod simulates:

• Real buoyancy based on displaced water volume
• Material density
• Internal watertight compartments
• Progressive flooding
• Floodwater weight
• Drainage system
• Pressure-driven water propagation between compartments
• Ship trim and list during flooding

The system is designed primarily for large, realistic ships rather than vanilla boats.

Features

• Physical buoyancy simulation
• Material density support
• Internal compartment flooding
• Drainage system
• Dynamic stability changes
• Pressure-based flooding
• Flood weight affecting the ship's center of mass
