The deck armour seems rather thin....

The deck armour seems rather thin....

Would you even call that armor?

LOL My error, sorry, I'm so used in entering armor in inches that I didn't realize I was putting...a quarter of a milimiter of "armor" there


updated now, changed secondary battery and belt, and added some true deck armor

It´s a decent design with little I would change.... Well, maybe her draught is a little bit deep given the shallow waters along dutch coasts (homewaters)...
