means of defence it was not unusual for these peaceful craft to be provided with turrets of great height, from which heavy missiles could be dropped on to the attacking pirate. In the bows, in the stern and amidships these erections could easily be placed and as quickly removed. And as a further aid oars would be got out in an endeavour to accelerate the ship's speed. For whilst the pirate relied primarily on oars, the trader relied principally on sail power. Therefore in fine settled weather, with a smooth sea, the low-lying piratical craft was at its best. It could be manœuvred quickly, it could dart in and out of little bays, it could shelter close in to the shore under the lee of a friendly reef, and it was, because of its low freeboard, not easy to discern at any great distance, unless the sea was literally smooth. But all through history this type of vessel has been shown to be at a disadvantage as soon as it comes on to blow and the unruffled surface gives way to high crest and deep furrows.
It is as impossible to explain the growth of piracy as it is to define precisely the call of the sea. A man is born with a bias in favour of the sea or he is not: there is no possibility of putting that instinct into him if already he has not been endowed with that attitude. So also we know from our own personal experience, every one of us, that whilst some of our own friends fret and waste in sedentary pursuits, yet from the time they take to the sea or become explorers or colonisers they find their true métier. The call of the sea is the call of adventure in a specialised form. It has been said, with no little truth, that many of the yachtsmen of to-day, if they had been living in other ages, would have gone afloat as pirates or privateers. And so, if we want to find an explanation for the amazing historical fact that for century after century, in spite of all the efforts which many
