Modern warships hulls are welded, you can only see them if you are very close. On scale models this is too small . Keep it as it is. Only in 1940's and before you may see panel lines. Example: Hms Hood bow has panel lines, the Bismarck hull is clean, no panel lines because the hull is all welded, like modern warships.
However some hull details are important to 1:200 scale, try look for them, in case they are missing .
