Before we left on this cruise, Laura canned quite a few pints of meat for use aboard, and it was great. Not heavily loaded with salt and other goop- just meat. She canned pint jars of chicken, roast and ground beef.
The only difficulty was the pints were just too much when used in various recipes, since we use no refrigeration, and thus are loathe to keep leftovers unless the temps are quite low
Of course, after 7 months aboard, all that was gone anyway.
So since we have been hanging around here in Boot Key for a while,, she decided to can more stuff aboard the boat.
We searched around Marathon, and found some 1/2 pint jars and bought two cases. She used the pressure cooker as a canner. It has 15psi when at pressure. 75 minutes of cooking and she could do 5 jars at a time.
So,, we now have 25 jars of various meats stowed in the meats locker ( she did 26 but we used one as a trial) and we're good to go. 1/2 pint jars seem to be perfect for the two of us for one meal. Plus she now knows it can be done aboard

The final product-she did ground beef, chicken, ground sausage and sliced link sausage.

and the equipment used-
