Any one of them could be cause for concern especially stacked on top of a sick kid. These folks made the decision to bail and call for help. Under the circumstances I think it was the right thing to do. Even if the skipper couldn't figure out how to fix the engine problem by himself, something I doubt, now that he has the CG guys are on board with the additional brain power if it could be fixed it would be. Sometime you just can't fix things. That's why I have a sailboat and not a powerboat. More options.
