The Israeli response to any closing on the Gaza coastline is, however, likely to be primarily influenced by the need to ensure that such events do not occur again. A start would be removing these 50-ish boats from that rotation.
Whatever tactics the Israeli Navy employs, their biggest challenge is likely to be the number of vessels sailing with the Global Sumud Flotilla, which could overwhelm the number of patrol boats the Israelis have available to interdict them.
The Sumud Selfie Flotilla could potentially aid Hamas and the Houthis then. The latest from the flotilla is that they expect to set off from Tunis on Sunday, September 7. They are expected to reach the Israeli coast and Gaza around mid-month.

The Gaza Flottilla has announced that they are planning to break the blockade.

According to the San Remo Manual which handles armed conflict at sea, the
ships must be inspected and this can be done on international waters.
The alternative is to redirect the flottila to an Israeli harbour for inspection. If the cargo does not contain any contraband, then the cargo should be forwarded to Gaza by the Israelis so as not to violate the blockade.

The inspection of cargo on international waters was determined legal by the Palmer commission in 2010.

The reason is that the blockade is legal due to the indiscriminate rocket attacks on Israeli cities.

The objective of the flottila is to
* feel good about themselves
* make morons scream about Israeli war crimes.
* make morons feel good about themselves.
* get a tasty sandwich at the expense of Israeli taxpayers.
As far as I understand, no one in the selfie flotilla to Gaza incident in June showed any interest in the cargo after they were sent home…so is this really about aid? I could also “what about” actual genocides taking place right now and this latest flotilla but why bother?

The Israeli Navy operates seven Shaldag Class high-speed patrol boats and 18 Super Dvora Class fast patrol boats for coastal patrol duties, and may have to call on helicopters and their 15 larger Sa'ar Class missile boats. Some of Sa'ar Class boats are in the Red Sea, covering the threat from the Houthis. Others are needed for high-priority tasks off the Lebanese and Gaza coasts. Hence the Global Sumud Flotilla is likely to impact ongoing Israeli operations in Gaza if it comes within range.Greta cloned herself. Now there's are 4 flotilla.
