It'd be worth mentioning that the mechanism has a directional requirement. It only appears to work correctly if it shoots you west (I think it's west, whatever 1 for the f value in the f3 display). The boat doesn't load correctly any of the other 3 possible directions. Considering you have one...
Not sure if you see it, but I'm talking about the weird slow-mo/glitchy distortion that appears on this video and Jesus on the Mainline.
