A big freighter with rocket launchers will defeat a fishing boat with rocket launchers.

Suggestion. Stay on land..you'll live longer.  Answer this question, what's easier to hit? A container ship that has a few million sq ft of FLAT reflective surface area and huge heat sources...near the bridge as a rule...or a small fishing boat with a few hundred sq ft.of surface area that can maneuver faster and present a smaller target?

Even though the problem sounds big,  ships are attacked at a rate of  1 per 3000 transits based on industry numbers. When they do attack the success rate is very low

That being said shipping companies are perfectly happy not to spend the money for security. They already said as much. Its cheaper to pay a ransom occasionally than hire security and outfit ships with deterrent capability.

It also takes more fuel to steam closer to the Arabian peninsular where the US ships are.

The upside is that they can charge extra for freight that must ship through the Suez.

And no this isn't me hating on the shipping companies. Its simply business.
