Sorry to revive an old thread
(and sorry to gunshot, as my initial PM was not very well worded)
Here's the relevant federal statutes -
18 USC 2277
a) Whoever brings, carries, or possesses any dangerous weapon,
instrument, or device, or any dynamite, nitroglycerin, or other
explosive article or compound on board of any vessel documented
under the laws of the United States, or any vessel purchased,
requisitioned, chartered, or taken over by the United States
pursuant to the provisions of Act June 6, 1941, ch. 174, 55 Stat.
242, as amended, without previously obtaining the permission of the
owner or the master of such vessel; or
Whoever brings, carries, or possesses any such weapon or
explosive on board of any vessel in the possession and under the
control of the United States or which has been seized and forfeited
by the United States or upon which a guard has been placed by the
United States pursuant to the provisions of section 191 of Title
50, without previously obtaining the permission of the captain of
the port in which such vessel is located, shall be fined under this
title or imprisoned not more than one year, or both.
It appears that guns are only illegal under federal law if you do not have permission of the owner/master of the vessel.
So, 18USC2277 basically gives the owner's wish the force of law. If a gun is discovered on board by the Coast Guard, one of the elements the boarding officer must obtain in order to arrest is directly asking the owner of the vessel (Metro Louisville in this case), "does this person have your permission to carry a gun on board?"
So, my question is, can Metro Louisville (owner of Belle/Spirit) deny permission to carry a gun on board without be in violation of KRS 65.870? Is denying permission to carry on board any different than denying guns into the Zoo or any other city building under KRS 65.870? The ultimate decision on criminality of guns on board Belle is whether or not the owner (Metro Louisville) gives or denies permission. 18USC2277 merely gives that owner's decision the force of law.
This is curious because it appears that there are other passenger ferries that allow guns on board based on state law permission (ie CCW permit) - For example, Washington State ferry allows CCW on board based on state laws, which is essentially "owner's permission" under federal statutes 18USC2277.
