Thank you for your very detailed, patient and clear explanations. I'm impressed, and happy to learn so many things !
I still have a few comments :

Yes, IMO no light should come from the bottom to create the AO map of a ship. I think that this is not realistic, because in reality you don't have any sun light coming from the bottom, but only very little light reflection by the sea. So, the solution (to avoid "undue" shadow on the cabin) would be to create the AO map on the cabin without the ship's deck occluding the light.

No, because in game the hull will receive as much sun light as the cabin, so the difference of illumination will be noticeable between hull and cabin (more "AO shadows" on cabin).

In game, the sail will be set as an optional equipment, so it will be rarely seen. The plan that this model is based on also features a mainsail, but that was used very rarely (probably in case of emergencies as noted by kapuhy) and I decided not to include it in my model.

Ok, I was suspecting something like that. I think it's a good idea to set the sail as an optional element.
