How did you get on? Did you manage to write down all the characteristics?
You were looking at a Safe Water Mark
| Safe Water Mark | Characteristics |
| Colour | Red and white vertical stripes |
| Buoy Shape | Spherical; pillar or spar with spherical topmark |
| Topmark (if any) | Single red sphere |
| Light Colour (when fitted) | White |
| Light Rhythm (when fitted) | Isophase, occulting, one long flash every 10 seconds or Morse “A” |
Morse code for letter ‘A’ is dot dash
If you managed to get all that - well done.
