Error when running polar diagram scripts for sailboat

[JeroenSmets]

Hello,
When I am running the sailboat scenario 1 I get an error that I attached as a picture. Also, the sailboat does not move as theoretically expected. I replaced the usv_base_ctrl and navigation scripts with respectively the sailboat_polar_diagram_control and sail_polar_diagram scripts.

Hello @JeroenSmets,

i remember getting these error messages but the experiment finished and i got the polar diagram in the end.. the polar diagram for this sailboat is in figure 10 of this paper https://www.mdpi.com/1424-8220/19/5/1068/htm

Hello Davi,

The problem is that the sailboat doesn't move when I run the sail_polar_diagram as navigation and the sailboat_polar_diagram_control as base control. So the simulation scenario will not end. Any ideas why this could be?

Kind regards
