Building the Drawbridge
Love the draw bridge. Can I make 2 suggestion?
1. Line inside with Kevlar to prevent splinters from taking out your crew (this was a problem on the old wooden ships) and to prevent bullets from getting through should an attack undermind or weaken a single area.
2. Protect the hinges, they are exposed to the enemy and to the weather. Frame them in with brick and mortar to prevent access to them.
