Waterlogged structure

I have a problem with making pirate ship.

Every block in this structure below water level that can be waterlogged (every chest, fence, ladder, iron bars, trapdoors, and every other waterloggable blocks i used) is waterlogged, i tried fixing it for hours and i can't fix it.

Please help i spend 2 months making pirate things for my mod and i really need this ships not flooded!
