I play on Noble and this happened twice last night. Gilgamesh had an island that I wanted with one city. He had about 12 destroyers in port and 3 infantry. My fleet of four ships and eight marines wiped out his entire fleet fo destroyers by doing an amphibious. He had declared war on me, but his entire fleet stayed in port.

Then I noticed that Hannibal had 18 destroyers in Carthage and one anti-air infantry guy. How can I pass that up? I declared war and made a surprise amphibious, taking out his entire fleet with a couple of marines.

The AI does not seem to know the difference between land and sea units defending a city and also doesn't deploy it's navy for some reason.

Hmmmm?
 
What difficulty? Because, in my experience, you're lucky when that happens. Nine times out of ten, those ships are running around causing all kinds of problems for you... The tenth time you get the satisfaction of blowing up an enormous fleet in port.
 
I'm also seeing a lot of problems with the AI keeping 30+ ships in a city with only one or two land defenders. While it does sometimes bring the ships out when land troops approach the city, more often than not it lets the whole lot be destroyed.

Difficulty level isn't of relevance to this kind of problem. The AI behaviour does not vary with difficulty, it's only the bonuses/penalties it receives that change.
 
Yeah my last game I played on Big and Small and all the major powers were on the same pangea continent, yet Hannibal had 40+ ships that sailed around my oceans, but other than lowering city defenses and blocking trade routes, he couldn't do anything. I dominated his forces on land and conquered him rather quickly because he overly concentrated his military production on his navy and ignored his land units. Since he was just south of me on land, I didn't even bother with a navy and my tanks rolled right up to his cities and conquered them.
 
I think that AI parks its ships when it's at pace time ... so provably you have done a civilization "pearl harbor" version.

My last game was totally different: AI did know how to use navy...

AI's are stupid. So if you want a challenge play humans! MP is the only way to play IMHO.
 
The AI will sometimes use cities as part of the pathfinding of a fleet. I killed a fleet of 20 trimeres this way - they were on the way to pillage my seafood when they decided to stop the night in one of their forts. The fort was unguarded and one of my knights charged in and burned all the trimeres while they slept.
 
The AI navaly has been more of a problem, destroyers coming in from the darkness and taking away my lead or tail ship.

The new ships available are good, and I've seen a semi decent naval invasion as well.

Wouldn't be the first time (even before BtS) where I have caught a navy at port.
 
I've only seen this happen when the AI thinks it's Navy is outmatched... so the ships are 'in hiding' while they wait on re-inforcements.
 
I must say I see ships huddling in ports all too often. Sure, if their ships are outgunned, they'd be lost if they left port. But when I'm hammering on their city and in all probability going to take it, it would be better to throw those ships at my superior navy in the off chance of doing some damage, or try to flee to another city. Because when my troopers march in, those ships are toast at no risk to me at all.

On the other hand, they usually go to great lenghts to take out privateers (though I've only ever seen the AI use them once, and it was a lone privateer bumbling around near my destroyers...). But the other day, playing an MP game vs a friend and a few AI's, he had a stack of 8-10 privateers blockading a couple cities. That AI had 50++ caravels around, circling and hovering the privateers but never attacking. That amount of caravels would be able to take out the privateers (3-4 to 1 is usually sufficient in my experience). So if he built them, in all likelihodd to counter the privateers, why not use them.

But I've learnt to avoid island-heavy maps now, the AI can't handle those near as well as more continentally oriented maps.
 
I had the same thing happen with privateers. I had about ten of them and the enemy had about 40 caravels circling them. I am assuming he got chemistry and changed his behavior because they all attacked suddenly one turn. He could have attacked at any time and been left with 30 caravels since 2 caravels can usually take out a privateer and mine were not stacked.

Unless you have a PA, a MP game is almost ridiculous. You can't possibly trust anyone. Only 1 civ can win a game unless PA is in effect, so what happens when no one has a PA? Are there any peaceful victories in MP? How can there be? If any 1 civ is close to a cultural victory, everyone would attack, no? Why would a human player sit by while a human rival builds his way to victory? A diplo victory? Come on now. Voting for another player is giving up your chances to win. I abstain at all times when I'm not up for election in the UN (single player). Same with space race. If you see one player building a bunch of space parts quickly, are you not going to go all out to stop him? Wouldn't everyone in the world?

I just don't get MP. Sure the military game is better, but how can you make any pacts with players when everyone is playing everyman for himself?
