Ted, wonderful to see you continuing on, even with your situation. Keep up with the PT and get home soon! My prayers are with you. Merry Christmas! RobI'm not sure on the height of the upper deck at the stern. Parts 11D and 12D are replacements I made as my cute little OCD wife tossed the original parts thinking they were trash. I rand the deck parallel to the one below and used 21mm as a height based on the height shown on detail T14 (see second photo).View attachment 565707View attachment 565708
