These posts on heavy smoke from the stacks being a bug are pretty fun. As a U.S. Coast Guard Officer with 8 years of sea time, I can tell you that you would get a lot of smoke from the stacks any time you went ahead full with both MDEs. In fact a cutter I served on was reported as "on fire" while we were leaving our home port. Sorry that this "bug" is causing problems, but it is pretty realistic.
