Sargasso weed. Someone checks the keel with the endoscope. Keel, rudder shots. Sailing fast through weed. Slomo. Closeup of weed. Alex, below, explains about weed on the foils. Nipper and Trystan can look to see what's on the foils. Tricky when it's dark. The boat hook is handy as well. You can half wipe out, and it will get the weed off.
