Design 

Aquarius is a tug boat from the 90's. It's excellent and free model was created by Jason Simpson and is available there:http://www.simpsonslipways.com/vehicle-simulator.html

This add-on  provides optimization for using this model in VSNG and 2 repaints. 

Features:
- new lighting including anchor and source lights (lights.cfg)
- adjusted mooring lines and anchor chains (cables.x)
- adjusted hook and cable positions in corrected elements.cfg file
- 4 spotlights
- adjusted bump files
- 2 repaints [yellow and white] called AKOA-Y and AKOA-W

Simply copy the files into the folder of the original vessel or create several renamed copies to have a small flotilla where each tug is numbered from 1 to 4 (for each version).
