Testing of the Hull Crawler continues in Port Canaveral, Florida. The crawler (I’m starting to refer to the crawler as Clyde because it just needs a name and I name everything including my iRobot vacuum) has been fit with grooming brushes and the crew is hard at work testing – tuning – retesting to get Clyde functioning as a grooming solution.
Down where the water is warmer.

Can’t quite tell what’s going on with this video but Clyde is grooming a hull and you’ll see the swath of clean blue hull appear.
