It has been a while but I spent my time well. The rough stern master is finished, in the picture below I have indicated all the parts of the stern assembly.
The towed Array Pod is provided with hatch openings
Picture below, all the leading edges of the control surfaces of the rudders and planes are provided with a radius. The clearance between the control surfaces and the body is 0.5 mmm.
All the different parts were test fitted without remark.
