Legs home
The Reef is 1 leg home; the Abyss is 2. Coastal Waters is zero, on purpose — a broke, bare sloop must always be able to reach port.
Each leg rolls the zone's own spawn table at 50% of its normal rate. The freed probability goes entirely to calm water — a leg is quieter than a chosen sail, and that is all it is.
Why it matters
A career that could reach port in one action could top off hull between every fight and win almost everything. Pricing the way home is what makes every other survival mechanic mean something.
