Can’t rescue the third hostage

assassins-creed-3

I tried playing AC 3 and got to the part where I'm freeing the hostages for the first time.

What happens is I get outside of the fort wall. As soon as I sneak onto the boat and try to free the hostage near the edge of the ship, I get caught. If I assassinate the guard first, I get caught still in plain site.

Is there more than one option?

I can free the other two, the ones within the fort, not get caught, AND EVEN assassinate the guards without getting caught either, if I take a few tries. But I seem perplexed at the fact that I don't see a lot to sneak around on the boat.

I did this mission last night. After freeing the first two sets of of hostages (easy), you need to kill the captain on the docks (hide behind some of the stacks of crates on the docks and get him as he comes around the corner - whistle if you're impatient).

Once he's out of the way, you can climb on the boat. There is one more guard right by the hostage and you should be able to take him out the easily.
