These ships are a pool of previous existing models.
Using nifscope I've modified dds files in order to reduce their number as much as possible.
Furthermore I've fixed the nifs where needed. Now every model works fine during each animated sequence.
All ships have shader and no-shader nif, and they use animations and xml reference of firaxis trireme.
The picture shows a whole fleet that I assembled using the above models and the galley ones, also varying the XML scale to obtain more differences among them.
