I say helicopter in Israeli commandos armed only with water pistols and video cameras and zip ties onto every boat the minute it passes inside the International Boundary. Physically restrain the captain and crew (using the threat of being squirted in the face with a water pistol) and direct the ships to off load their cargo in Ashdod. Have the international media film every step of the unloading of the cargo and its transport into Gaza, along with the "activists" on board. Maybe drop them off at the new shopping mall in Gaza City to peddle their wares there.
