On the hull are a lot of details, every opening in the bullwark will have a 1,5 mm braas wire around it just like the topside of the bullwark.
The brass wire around the openings is providing a nice finish and also reinforce the bullwark.
At the inside of the bullwark there will be the supports, made out of 0,4 mm pcb board, soldered to the deck. This will reinforce the bullwark also.
On the bow the fender is mounted on a structure made with 1,5mm pcb board and the 12 mm fender mounted to this.
