The Maersk Alabama was attacked for the 2nd time. They now have on board security personnel armed with a Long Range Acoustical Device and guns.

Check out the article http://news.yahoo.com/s/ap/piracy

I understand the pirates frequently prefer to aproach from astern. Have you considerred mounting a small closed array off the fan tail, just below the rail?

Also give your look-outs infra-red gear for the night watches. Remote control IR cameras might be useful too and one or two crew members could monitor several angles.

Good luck!

Adjust your radar so it looks like someone threw salt on the screen....little dots. If you leave it in auto mode you are going to miss small targets. I pick up pangas in MX at about 6 miles. You just have to make sure the gain is up.

Agreed. The higher the radar, the more sea-surface reflection it suffers. (The higher the radar antenna, the more directly the signal hits the surface, and therefore the more noise in the return signal.) If the target is not beyond the horizion (at the antenna's height), the extra height hurts, not helps. I am not sure about the math, and part of the equation involves the height of the target, but I suspect that as little as 20' would be the best height for 8 mile detection. I also suspect that even a 25kw radar isn't enough to get a return on a small target beyond that range.

I have to ask the obvious, can't believe nobody has yet.

How does a group of thugs in a small skiff takeover a huge tanker or cargo ship????

Every non-military ship has boarding ladders welded to the hull - allows Pilots to come aboard or leave - a necessity for port calls. Even though those ladders at 10'+ off the water, they grapple on to them and hoist themselves up. Since they are armed and the crew is not, once on deck, the ship is theirs.

Cover the ladder steps with something so they cant get a hold of it. Or connect some high voltage to it

It still baffles my mind. Fire hoses, steamy hot water, boiling oil, bilge water, sewage, the list goes on and on. These guys are 40 feet below.

40' below, BUT with GUNS and shoulder rockets. Pooring sewage on them would be fun, but the gun fire coming back at ya wouldn't be.

Picture a supertanler full of something flammable.

Now picture an rpg. That's the big threat.

The real question is why don't these ships just form convoys and bring along an escort..... non-lethal and effective, at least for the ship owners. The escort can do what it needs to.

It may come down to that but the ships are coming through on varying schedules and heading to/from many ports up and down the coast and over to Asia and Australia. Having all those ships close together has hazards of it own. It's not like WWII when all shipping was organised and controlled by the governments of USA and UK. That convoy system took a long time to organise too.

If it were up to me I'd have the navy launch cruise missiles into those McMansions going up in the pirate home ports.

I can just hear it now, "Ah, well judge, we were about to take over a ship and takes it's Capt hostage for money and they just started shooting at our skiff!! Arest them!!"

It's going into a port that is the problem. Most countryies wont play nice with the capt, first officer and the rest of the crew.
Might think you are trying to over throw their country.

Even if civilian entities could buy them - and I doubt they could, since shipowners won't even spring for $100k/yr to hire three armed guards to do security, do you really expect them tp spend $1.4 million per gun and hire a technician to operate it?

On this season of Whale Wars the Japanese used an LRAD acoustic device to disable a prevent an attack. Looked preety damned effective to me.

Here is the answer to the OP. I just read it on panbo.com. Pretty slick adaptation.

These ships have very small crews. If the skiff is not detected before it gets close to the ship, the pirates can board. There are a number of ways the bad guys get on board, such as using the existing ladders, grappling hooks, etc. Our military trains extensively in boarding hostile vessels, we even have specialized forces such as USMC "Raiders", SEALS, etc. The pirates can and do use the same techniques that our military does.
Once on board, just a couple of guys with small arms can easily take down a large vessel with a small crew, especially if surprise is on the side of the pirates. Add a couple of explosive devices, and it's easy to understand how the bad guys take down very large vessels.
With early detection, the bad guys really do not stand a chance. A ship could easily be defended by it's crew from a small pirate force that is only armed with rifles and RPGs.

Uhmmm...if you worked for an ocean shipping company why are you asking about radar questions on the internet? Are you direclty in charge of making this expensive purchase and asking about how to do it by a bunch of strangers? I would assume the shipping company would have an electronics specialist that is directly in touch with Furuno or the like.
