Here's a sketch I did a few months ago that I never scanned in. It's a sketch of an authentically restored full sized ship of the boat made famous by the Boston Tea party of 1773. The ships actually much smaller than I had imagined.
This tourist spot allows people to board the board and experience throwing in wooden crate boxes into the sea. The boxes are made out of something light so they float and then the staff members would pull it back onto the boat for the next set of people to push it off.
I didn't board the ship but had fun sketching this and watching the people on this beautiful day.
