Same here, even when using https://www.nauticed.org/images/basicsailtrim/degreesoff.jpg as a guide to pass it, I cannot get it to accept me as a human.

The captcha seems easy for a program to overcome though, so maybe it's meant to stop humans and allow robots?

you just need to know that there are 360 degree in a circle. now do:

- count the segment dividers and divide 360 by that amount, let’s call this X.

- count at which divider the pointer is pointing, multiply that by X and be good.

The compass is not always oriented so that North is up.

The interface is barebones. You need to understand a compass to use it, I can solve the captcha but not figure out the controls.
