Thanks for the info, I guess Ill just keep messing with it on and off until something happens :P
Edit: Well for whatever reason I can change the files now and I was messing around and changed the gc value to 4 and the boat is upside down

lol good stuff
Edit2: Hmm after testing some more I am definetly affecting the boat, but not in the same manner as before. The boat still looks as though it is on rails. Does your boat still look like its on a rail trimzeke especially when you leave the mass at 0?
Edit numero tres: I feel stupid now, but I forgot to change the sim.cfg file They made a HUGE difference. When I use a mass of 845 with the sim.cfg I get a dramatic effect, but along with the depth keeping problems. At best its around a depth difference of 8ft, but I think it increases with depth.
