That a little boat should wait on him (ina ploiarion proskarterh autwi). The boat was to keep close (note present tense subjunctive of proskarterew) to the shore in constant readiness and move as Jesus did. Whether he needed it or not is not told, but it was there at hand. Lest they should throng him (ina mh qlibwsin auton). Press or crush him. Jesus stayed with the crowds for they needed him. Present subjunctive again.
