I will change the props to something more appropriate (off the Dunkerque).
The breadth of the ship is 102ft, the crane is mounted 12 feet off center and has a reach of 55 feet, so it should extend at least 15 feet outboard which should be enough.
I am happy with the way it looks too, even the big blocky funnel somehow looks 'right' on the design.
Most of the Netherlands major warships ended up in the East Indies guarding the exports that paid for the ships.
For Alvama I see I need to show the original drawing so that the 'twicks' can be seen more easily.
As can be seen I have changed quite a bit of the detail of the ship.
