Basically, I got tired of repeating this in PMs and I decided to make this thread. Also, it's a nice feature for lots of mods. Asrite, sailing.
First of all, you're going to need to get the ships and ship scenes in game. You can download them here:

Alls you have to do is take the file in Textures (longship.dds) and extract it to your Module's Textures folder. Then take the file from the Resources folder ("sail.brf") and put it in your mod's Resource folder, and then of course put the two files in the SceneObj folder (scn_sea_b and scn_sea_land) into your mod's SceneObj folder. With that done, open up your module.ini and add the following line:
load_mod_resource = sail
And then make sure that "scan_module_textures" is set to 1. (It should be.)
