The only time a charge is levied by the USCG is when the situation is proven to be a hoax ... an intentional false alarm. Even here the USCG does not actually levy a fine, rather presses charges which must then go thru the courts. USCG has 'standard rates' for resources (this is Government .. it is in a regulation!) and the charges will include a cost figured at X hours H-65 Dolphin helo at $YYY, etc.
With regard to a pass' on a cruise falling off and assessed a charge for the recovery ... my OPINION is: I suspect on a cruise, if you, a passenger, go over the side and are quickly recovered your fine is being put off the ship at the next port ...... no do-overs, do not pass go - do not collect $200 - bye bye. It is the discretion of the Master to put anyone off the ship at any time ... it is in the contract you sign. cuz IMO there is virtually no way to
accidentally fall off a cruise ship. For example ... has there been a single case of a CHILD falling off a ship? Not that I can recall, altho without meaning to be cruel there HAVE been cases a 'inattentive parents' resulting in other 'incidents' injurious to children. While there is an exception to every rule, IMO stupidity and or alcohol is in play in 99.9% of the MOB cases. In my years on ships much smaller and much more dangerous than a cruise ship I had ONE man overboard: this happened in port when a crew member sat on a life line - which is
proscribed because it is dangerous to do - the line was equipped with a quick release device which was improperly fastened and
let go and the member fell over the side .... with no physical injury & to the applause of the many who saw him go! But I digress ....
***********
every country I'm familiar with requires their licensed mariners (read Captain/Master) to 'render assistance' until released by competent authority. In other words, for something in the Bahamas all ships in the area would respond to a MOB alert, until USCG was on scene and released them .... sometimes USCG assigns search areas! Depends on the case .... Bahamas almost ALWAYS immediately requests assistance of USCG for 'significant SAR' in their waters which is provided as long as assets are available. This is a 'fee' paid by the US for allowing US "assets" to be "forward deployed" in the Bahamas for other US missions
Google OPBAT ......
"U.S. and The Bahamas has permitted establishment of a significant interdiction and investigation infrastructure involving U.S. aircraft, ships, and personnel. Supported by INL, Operation Bahamas and Turks and Caicos (OPBAT) is a combined effort by The Bahamas and Turks and Caicos Islands police and the Drug Enforcement Administration (DEA) to intercept loads of cocaine and conduct investigations. OPBAT employs U.S. Coast Guard and Army helicopters assigned to joint interdiction bases in Nassau, George Town, Great Inagua, and elsewhere. INL is assisting Bahamian security forces to develop a more effective maritime end-game capability. "
