安全港船舶公司的总经理弗兰克·科瓦尔克斯告诉每日邮报网站说：“保持船只直立需要满足3个条件：非常低的重心、船舱的浮力和船舱的水密性。船舱里必须有足量的空气来保持船只漂浮，而且千万不能有水进入船舱。”

To ensure that the boat maintains its high buoyancy at all times, its air inlets close automatically.

为了确保船始终保持高浮力，船的进气口会自动关闭。

The low center of gravity not only makes the Thunder Child harder to flip over, but in the off chance that a strong wave does manage this feat, when underwater, the center of gravity shifts to the very top of the boat, making it extremely unstable and able to flip back to its normal position.

船的低重心不仅让“雷之子”不容易翻过来，而且即使运气不好一个大浪把船打翻了，船在水下的重心也可以转移到船的顶部，让船变得非常不稳定，从而能够翻回到正常的位置。

To prove that describing the Thunder Child as impossible to capsize wasn’t just a bombastic claim, the Irish company recently staged a demonstration where they used a crane to flip the boat over to 180 degrees while on water, not once, but twice. The first time the boat was empty, and the second time with a small crew. In both instances, it returned to its correct position almost instantly.

为了证明“雷之子”不会倾覆不是夸大其词，这家爱尔兰公司最近还做了一次展示，让起重机把水上的船180度大翻转，而且是两次。第一次船是空的，第二次有几个人在上面。两次船都是几乎立刻回到了正位。
