1. Fresh fruit.
2. 16-ton weight.

[Soothesayer]

Awesome. Large vessels are also high off water level so it will cause quite a bit of damage.

Killing with firearms is more fun and reliable. Sinking a boat with a cannonball in open ocean will probably result in killing the pirate anyway so why fool around and pretend there is something wrong with using firearms?

[Hodar]

Why not simply use the firehose to spray them with some flammable liquid, then toss a match.

You are not ‘armed’ in the conventional sense. Gasoline flushes out nicely with water, as does Diesel. Both float on water, stick nicely to skin, wood and fiberglass. And everyone is allegic to fire.

[Soothesayer]

You can also try dropping chunks of old ham and dog feces. Somalis are muzzies.

[GOP_Party_Animal]

Kinda hard when they are shooting at you.

[SeminoleSoldier]

Burning oil too.

[JimRed]

Good idea, since it is very difficult to keep boiling oil close at hand!

Maybe containers of an acid or corrosive...

[DesertSapper]

Mount M2 .50cal mg’s strategically around the boat. Those .50BMG rounds will make swiss cheese out of nearly anything.

Throw sticks of Right Guard at them.

"...We encourage merchant fleets to experiment with these techniques in advance to make sure they will work. (That is, an encounter with pirates is not the first time they should be tried. As an example, the crew should experiment on empty skiffs similar to those used by pirates to see what will work.)"

Change that to "manned skiffs" and we finally have a use for Gitmo prisoners. :>)

[Jane Austen]

Use pork and pork fat.

[1010RD]

Does anyone know the maritime law that allowed armed merchant marine during WW2?

Why can’t that just be re-instituted and limit the anti-self defense laws currently blocking them for each port of call?

[BlueStateBlues]

Sea Turtles

[AngelesCrestHighway]

Discharge the boats sewage on their heads?....

[nmh]

Good grief!

USE GUNS.

Use whatever you have to eliminate them permanently.

[Tahoe3002]

Maybe the ship’s captain could give out rewards to the crewmen for most pirate boats sunk?

Five boats and you get to be an ACE!!!! They could paint little motorboat symbols just outside the ships bridge.
Maybe some international competition? Come on, let’s be creative.

[AngelesCrestHighway]

Drop granades in their boats?

[2harddrive]

Molotov cocktails, made with 1 to 5 gallon glass bottles of gasoline would work GREAT, too!

[Labyrinthos]

Surplus bowling balls.
