Here are some great 3D animations of the Ethan Allen prepared and for sale at a company called TurboSquid (click each photo for larger image).

Seeing a full profile from the bottom of the keel to the top of the canopy is striking. Notice how little of the vessel's bottom is below the waterline. In layman's terms, this boat appears top-heavy. This means that a knowledgeable boat owner / captain should have been aware that a stability problem might exist.
A question has been raised at the BoatDesign.net BBS as to whether these 3D graphics are an exact replication of the Ethan Allen. I have to agree. If you look at the GUNWALE (the upper edge of a boat's sides), towards the bow, it certainly appears that there is more upward curve than on the actual pictures of the Ethan Allen. Also, the windows do look taller than in the photographs. The origin and purpose of the 3-D graphics is unclear. However, I think the graphic does offer some idea of how high the center of gravity must have been on this boat and how slow the righting moment must have been as it heeled (tilted) to either side.
