That's a tough shot. The foreground has nothing useful, and the ship in the distance is so far off that it's not offering much in the way of parallax for a 3d track. I don't think there's any hope for an automatic solve on this one, but you might be able to create a more usable tracking plate by creating some tracking markers and doing some semi-manual animation of them to get something that Boujou is able to track.

I think I would start by doing a 2d stabilize to get rid of the rocking and rotation, then maybe try a few planar tracks, or possibly point tracks with frequent pattern evaluation—probably every frame—and a large pattern sample. Then I'd attach some new objects to the x-axis motion of those trackers (because you don't want the y-axis motion from the waves, just the lateral motion of the camera). Then I would reverse the stabilize and render it out as a new clip for tracking. Theoretically, that should create some points in the fore- and mid-ground that can be used to solve the camera.

I've never used Boujou, so I don't know if it has tools that could simplify a track like this or not, but I'm fairly sure that PFTrack and the Foundry's CameraTracker would both have a very hard time with it. And I have no idea if the process I described above will work, or if it's complete lunacy, but maybe it's a place to start.
