Adds tables to allow for damage (and combat) to vessels. Each vessel uses a D6 to track damage (starting with "6" and decreasing as damage occurs). Adds "flotsam" (deliberately created "Log" hex) to hazards of journey. Due to the nature of "combat" - vessels pushed on Sand Bar were allowed to change facing if "pushed" onto them (rationale: Captain would react to the collision and maneuver to advantage).
