Thanks James and Kenny,
I did not used any other p.e. only inbox p.e. used for Sboat. Only its base from a 1/700 Pitroad kit.
My campaing build Heianmaru  needs some extra p.e. I had to stop on it for until I receive parts for gun platform floors and boom puleys. 
I could add more details on Sboat, like around fwd 20mm and its mount,  but I wanted to build as what kit offers. It can also be a good companion for a Uboat, in diorama. Hey, I will buy one more
