In case your wondering the chainplates attach to wires that hold up the mast so they are pretty important. :) The one pictured here was on the stern.The previous owner Mike replaced the chainplate and pretty much painted the bottom of the boat by himself. From the sounds of it the paint was pretty noxious so I did not miss out much by not being there to inhale fumes.
Here is a picture of the boat up on the stands in the work area.

Thats Mike up on the boat doing something.
Here are a couple of videos of the travel lift moving the boat out of the work area and into the water.
Here is a picture of the interior from the cockpit.
