Well, I found the "entrenching tool" and even got through the spider cave to be able to swim out to that wrecked ship. What the hell do I do from there? I don't see anything around or aboard the damn vessel. There's a hole in its aft with a gold bar at the bottum. But I don't see anything else. What do I do once I get to the ship?? Someone please help me

I looked at both cranes. I couldn't find any arming device. Please, please go into more detail. Is it the crane with water surrounding it? Or is it the crane with a big crate next to it?

On the Ship near the crane is a little box ...Inside the box is an arming device .. take it swim back to shore and use it in the torpedo .... From there on ... Hammer around

what are the things you have to do after you open the door to the captians cabin?

You can pick up something to help with the crane or a med kit and a treasure are below you.
