320 image pano, how to stitch?

Ok a client asked for a very detailed panorama of my home town, so i went up into a mountain and took the photos with PLENTY of overlap, it came out to be about 64 photos per row, 5 rows, at 200mm I’ve checked them and the overlap seems to be plenty, one major thing is that there is a lot of ocean, some of the photos with no visible parts to lay down control points.
I want to see if its possible to save me the hassle of doing the CP manually, I have tried several programs with different results, none acceptable.
Autopano yields HORRIBLE results, even with the highest settings.
Panorama factory does not seem to support multi rows (does it?)
PTgui on fully auto seems to work very bad also 
Autostitch seems to be better option; can anyone recommend good settings for this? (I have no idea how to set it up for an optimal stitch)
Or any other ideas on how to stitch these images? Preferably automatic 
Even if it’s row by row, the major problem seems to be the ocean part.
Thanks
Shanti

I would try PTGui NOT on fully auto. If there are images with no features for control points, then you need at least some manual intervention somewhere along the line, whatever you use. I would use the Image Parameters tab to arrange the images in their approximate positions, using the Fill Yaw button and setting the pitch of all the images in a row to the same value. Then proceed in stages, optimizing a row at a time to begin with. You should be able to link pitch and roll parameters, as these will be the same for all the images in a row (if using a pano head, of course). Leave floating images until the end and interpolate their y,p,r values from their neighbours. You might also consider stitching with Nona to output cropped tiff files for enblend.

As John suggested, you can use Nona to output cropped tiff files and to blend one row at the time using enblend line command parameters or enblendGUI, then to blend rows vertically.

I am a bit surprised that the ocean is a problem, usually water or clouds are quite easy, anyway, check if you have any control points on those photos - none of the points is good, so just delete them (for the ocean only of course), then you can generate a pano and open it in photoshop and then just correct the errors using stamp tool - any thing you copy will be fine - it is the ocean, also you can generate a stitched pano and layers together and then just correct some errors
the bottom line is that everything on the ocean had moved before you took another photo - so you do not have any good control points at all, sorry, in this case automatic setting will probably not work at all, if you want it good - DIY
