Acts 27:14

14-17. (14) "But not long after, a tempestuous wind, called Euroclydon, struck, against her, (15) and the ship being seized by it, and unable to face the wind, we gave up and were driven by it. (16) And running under the lee of an island called Clauda, with difficulty we were able to secure the boat. (17) When they had taken it up, they used helps, undergirding the ship. And fearing lest they should fall into the Syrtis, they lowered the sail, and so were driven." It was just as they were rounding Cape Matala, and expected to be borne by the southern wind directly to Phoenix, that they were whirled away by this tempest. The direction from Crete to Clauda is south-west; the wind, therefore, must have been from the north-east. This is indicated by the name Euroclydon, which Bloomfield translates "the wave-stirring easter." Such a wind, varying from north-east to south-east, is said still to prevail in those seas.

While passing under the lee of Clauda, the island checked the violence of the storm, and enabled them to take some precautions which were impossible in the open sea. The first of these was to "secure the boat," which had thus far drifted astern, and was likely to be dashed in pieces. The second was to undergird the ship, a process called frapping in modern style, which consists in passing heavy cables under the hull, and fastening them securely on the deck, to prevent the timbers from parting under the force of the waves. The third precaution was to lower the sails, so as to prevent the vessel being driven too rapidly before the wind.
