These aren't mine, but here's a link to some great Pirate and Privateering Games put on by Battlefield Hobbies:

I believe most of the vessels seen in the games are scratchbuilt by the Battlefield Hobbies crew.
Please feel free to share your photos and links to great looking pirate/privateer era games, and/or any vessels used in them.
