Britain, is an island. Surrounded by a cold and unforgiving sea. For centuries it protected us from attack. But to prosper and thrive, we would need to do more than hide behind her salt water shield. Britain needed brave men, willing to venture out into the unknown and she needed good boats to take them there. I've spent my life at sea. Now I'm going to take passage on six boats that together, tell the story of modern Britain. Built for exploration, war, fishing, industry and our very survival. These are the boats which built Britain, and changed the way we live - forever.教官对楚翔的思想有极大感应，知道楚翔不是敷衍他，于是只能闭嘴不再言语，而这时候T4久攻不下改变了战略，它们分出一部分兵力开始固定位置对楚翔射击，如此一来楚翔的处境更危险了，各种垃圾被T4抛掷后威力惊人，一不小心就被一个轮胎打在胸口，楚翔倒飞出去十几米才收住身体，后背上的教官撞在墙上差点没把胸腔挤碎。
