For a personal project, I find myself needing to know what ships of the medieval Chola Navy looked like - my particular interest rests with the Thirisadai and Vajara classes. My own searches on the topic have come up empty, for the most part. Accordingly, I am asking you to assist in this search, in the hopes that you might have better luck finding good sources than I have.

To be useful, pictures of these ships should show them from the side, front, back or top. A view of the ship from beneath is unlikely but would be nice. Colour images are preferred, but black and white is acceptable as long as there is enough detail. Photographs are probably more than we could hope for, but don't ignore the possibility.

If you choose to help with this, thank you. If you do not, it is not your project and you had no obligation to do so.
