What should I watch out for at Johns Pass?

Foul ground reaches about six-tenths of a mile southwest from Stuart Island off the pass's south end — give that corner a wide berth.

What does Class 2 mean?

Class 2 is BoatRoutes' own 1-to-5 rating of how costly a timing or judgment mistake is here — it is not a NOAA scale. Class 2 means one thing to plan around (depth, a schedule, or mild current); getting it wrong costs time, not safety.
