Minimum Hull Size?

Hey All,<br /><br />Was just reading through some of the Dragon articles, and they had some ships that were HS: 2 that had a Laser Cannon installed, and in the KH book, it's listed as MHS: 5.<br /><br />Did I miss something? Did I put Deuterium in my Ion Drive instead of Hydrogen?  No, wait, It's that cloud of space wasps I flew through.  I'm still picking those off of my windshield.<br />
