Yep..I made a Ship that I could stand on(Qeynos)..I guess just try gender 0 or 1... Maybe 2 works too but had already deleted that one by the time I figured out that its not super solid. Its possble to slip through walls and the hull.
But one can stand on the deck. Oh.. my class type was 2 but Im sure 1 will work. I just used an experiment button I made an just changed the race.
But I guess a ship can cast spells on itself if one wants it to. I will try it for my ghost ship idea. I dont think I can stand on that one(Timorous Deep) but thats OK.
I will try to spawn something on one and see what happens. I wonder if npcs can ride?

I'd assume they can if a player character can. Though I'm not sure, thx though. Not having ships just bothers me lol.

Spawn a ship race 72 and set the gender to zero, it works..and I think it works in any zone.
