Martha asked fer help. Someone's gotta report back?

Do these small boats really keep logs?
As to the legal questions - it depends
. on local law. on Federal (US) law. etc. Common carriers are not strictly liable in all jurisdictions. In some cases federal common law will allow waivers of ordinary negligence but not wanton and wilful misconduct. a small dive boat may not be a common carrier. it may or not be subject to fed law depending on its size or where it operates. and so on.
