Madoka had spent her time building the boat being a helpful little thing. In a way this was exactly what she was made for. She loved building, she loved tools... and even if this was not what she usually did, she felt at home.
Rushing around with tools, crawling into places other people where to tall for... Madoka was comfortable.
She had a smile for all of the other workers, but mostly she was concentrated. While she was ready to rush to help anybody with a problem, for the most part she focused on building.
It was fairly obvious that she was fully ready to continue doing so for the entire night, too.
