Hi Ronald,
As you don't provide any pics then I have to assume you are referring to the two gunports at the stern, under the gallery. Therefore, Stage 25, Section on
'Cutting the stern gunports', step 2 clearly says 'Draw two lines at right angles to the first two, positioning them
24 mm from the edge of the gallery support at the point where you drew the first lines. (See attached pic). If these are not the ports you are referring to then you'll need to give a little more clarity....
If you are referring to the last gunport on each side of the ship then Stage 23, step 6 says 'The gun port closest to the stern comes midway between frames 29 and 30. Make sure that you keep its sides parallel to the frames'. (See 2nd attached pic)
You should follow the measurements given in the instructions otherwise your stern gun ports will not look right.
Hope this helps...
Regards
Alan
