Can't add boats

[patrick-5546]

Will not fix this for Raye, but might look into this for the new project

Description

rostopic pub /new_boats ... doesn't work anymore

Relevant Code

• python/MOCK_AIS.py

Initial Thoughts

• I think it stopped working properly since Added feature to change number of boats during runtime #239
  • I was able to get it to work by removing these changes
