As FLS's representative on what ships are and are not being accepted for the game, I believe we've already responded clearly: the Santissima Trinidad is not appropriate for PotBS. As others have mentioned, one can always build a model of her, but we would rather see the community's efforts go towards ships we can actually use.
Since I've already responded to the original suggestion, and since this thread seems to be edging toward a flame war (not that I believe it's intentional), I'm going to close this thread.
Again, we're looking for ships with fewer than 50 guns, which were built and used in European-controlled waters between 1660-1740. The 3DSC will gladly consider and provide advice on projects that fit within these criteria. Larger ships, or ships outside of this time frame, are simply "for fun."
