Sanding to "get the blue out".
Started using the second Stinger Wet-Dry Vac .
Sanded the port side from the stern forward to the midships jackstand and a bit farther forward on the keel.
This portion of the hull is done but for under the two jackstands.

Used up another Ridgid R26011 . Double action failed so that the sander switched to single action, spinning at high speed, only. Able to remove a lot of material, but demanding to handle and easy to gouge the hull. This one was obtained under warranty on 2022-03-01.
