I was told by a CG testing officer that for the purposes of logging
Merchant Marine hours they felt it was breaking the law to stand watch
more than 12 hours in every 24. So, I'd guess you're pretty safe
legally (in the USA) if your single handed voyages last 12 hours or
less. In practice I know a lot of folks who sail all over the world,
check in and out of countries and even log into national radio watches
without getting into any kind of legal trouble.
