The modular ship system will include several different ships and their modules.
Currently the 20m Ship (like Jamaca Sloop) is in Work
All modules fit to the respective ship,
The equipment is usable for all ships.
All modular ship parts will also be compartible with all following ship types.
If you don't like the modular design, please note that you also would need the textures if it were one single mesh.
It is, after all, a thirty-meter long ship and the textures are used as sparingly as possible.
The drawcalls could not be reduced at all without a massive loose of texture quality.
The whole system is very carefully thought out and optimized.
