Editing Joshua Pawlicki's Explanation of How It Works (section)

===''Hull''===
Simply put, a puncture in the hull of a ship in space will destroy it. The hull is designed to withstand internal pressure, and the lack of external pressure may cause it to implode on some designs. Some ships have failsafe systems that separate sections and rooms of the ships into miniature airlocks so that it is possible to, say, seal off the bridge when it's smashed and maintain atmospheric integrity and pressurization in the other chambers. Keep in mind that holes can be made from the inside, too. Some sections of hull can be safely punctured, however. Those that contain only wiring and materials that could normally survive in the vacuum of space will be fine.

A boat can usually take some punctures while in atmosphere, assuming the pressures are somewhat constant. Thus, people and cargo may be sucked out through the hole, but the hull will not implode.
