**Explanation:**

- **Tragedy Degree: 2**
  - The story contains some elements of tension and worry due to the storm, and Marina's anxiety about the ships in the tempest, but these elements are not profoundly tragic. The story resolves peacefully, emphasizing hope and resilience rather than delving deeply into tragedy.
  
- **Comedy Degree: 4**
  - While not strictly comedic, the story has light-hearted and uplifting elements, especially towards the end. The finding of the note in the bottle from a saved sailor adds a positive and somewhat delightful closure, but it does not have strong comedic aspects throughout the narrative.
