The "Crusier" version had a wider deck house, and a small dog house forward like the Tom Cat. I tried to find a photo on the internet, but couldn't. I may have some photos I took when I was in AK--not sure which computer they are on. I'll try and look thru my photos.
You could make one out of plywood. The Ameracat 31 had a similar small trunk cabin forward made for one boat which had a pilot house and seating for diving. They put a bunk down there, just like the Tom Cat.
For the current boat you could cut our the foredeck and raise it--with a step up for the entire deck (our of plywood), then cut an opening to the bunk area in the center. Looking at the photos of the fishing boat, there is at least a foot, to 18" of height above the current deck (but you have been aboard these boats and know the fishing boats better than I do) There is probably room in the hulls to put in quarter bunks, and maybe even a head (?).
Run the boat down un its own bottom and fish along the way! (Start at the end of the season--have a phantom buyer--so the Boss doesn't know!) Be a great trip, and you would have a great boat--next winter put the raised fore deck on it an you have a killer boat!
