1 tn BDAG 889 s.v. πρόφασις 2 states, “προφάσει ὡς under the pretext that, pretending that…Ac 27:30.” In other words, some of the sailors gave up hope that such efforts would work and instead attempted to escape while pretending to help.

Ac 27:41 is a semantic unit signifying a point (of land jutting out with water on both sides).” However, Greek had terms for a “sandbank” (θῖς [qis], ταινία [tainia]), a “reef” (ἑρμα [Jerma]), “strait” (στενόν [stenon]), “promontory” (ἀρωτήρον [arwthron]), and other nautical hazards, none of which are used by the author here. NEB here translates τόπον διθάλασσον (topon diqalasson) as “cross-currents,” a proposal close to that advanced by J. M. Gilchrist, “The Historicity of Paul’s Shipwreck,” JSNT 61 (1996): 29-51, who suggests the meaning is “a patch of cross-seas,” where the waves are set at an angle to the wind, a particular hazard for sailors. Thus the term most likely refers to some sort of adverse sea conditions rather than a topographical feature like a reef or sandbar.
