WesWorld

Hi, boys.

I have drawn a copy of ship which name derfflinger.

I think It is a good desgin drawing for myself.

~0`.

Please give me suggestion if you have ...

oh,oh,oh.

Looks nice.

Please use the proper folder for posting non-Wesworld designs.

I like her.

But isn't the bridge kind of low.

Well done. Nice drawings.

Some minor points:
- turrets seem lacking height
- bridge is too low
- RF on forward main mast will be prone to vibrations
- ...

I don't think that the turrets are lacking in hight.
But You do have point with the range finder.It probably has limited usefulness being on the mast.
At first I believed it is a enclosed spotter room/box

oh,oh,

New derfflinger data is following list as this:
