The rules can't account for everything.  This tactic however, while rarely used, is valid.  Any ship can carry many more men for a very short time than it can support over a longer period.  The limits of life support and food and water supplies make this evident.<br/><br/>But some ships in the Napolianic Wars for example, would load up on all the marines from a half a dozen other ships before making a specific boarding action or cutting out expedition.<br/><br/>In game terms, I suggest TGT can just give our boarding action a bonus...
