Viewing the keel bulb
WEBSITE: http://www.teachertube.com Rich Wilson shows the keel bulb of Great American III. The keel fin and bulb are mounted on the bottom of the boat to keep it upright in the water. The keel fin plus the keel bulb at the fins base weigh 3715 kg. The reason that we can see the keel bulb in this video is not just because boat is heeling but also because the keel is hinged on bottom of boat and is angled in the video about 40 degrees from the vertical of the boat.
