Just to be sure the base is covered we run the "Marine Traffic" app on our IPhone 5 and IPad. Shows all AIS broadcast traffic with ability to get details and a track on the targets. App is free. There are some in app purchases we have not made.

"...Just to be sure the base is covered we run the "Marine Traffic" app on our IPhone 5 and IPad. Shows all AIS broadcast traffic..."

Caution with relying on internet apps for ais info.  It is my experience especially on the rivers that Marine Traffic does not show all traffic unless near a land based receiving relaying station.  Of course you must be connected to the internet to receive the info which can have a significant delay beyond the Class B versus A transmit protocol.  In many very rural areas there are no land stations to receive info.  There are ship tracking satellite subscription systems but require internet connections as well.

I can confirm that Marine Traffic (and its competitors) shows nothing
here in the Bahamas outside of Nassau and Freeport and perhaps a dozen
miles out. It never knew where we were when we were in the Exumas,
Eleuthera, or most of the Abacos (we have a full-power Class-A
transponder). If you follow our link, below, it shows us just leaving
Nassau, but we are already in the Berries.

A close relative has just died.  His will request cremation, ashes scattered at sea.

I will probably be the requested boat to perform the ceremony.

has anyone performed this ceremony, is there any protocol which is suggested?

I assume that the only coast guard or environmental issue is that it should be beyond 3 miles.  Any other?

Thanks in advance.

Yes, and after several inquiries to various government authorities could
not find any official approving authority but was candidly advised to just
do it. Ashes are sterlized by the incinerater. So honored  the deceased
persons instructions to be buried in the Patuxent River which he boated and
love.  It was very simple but poignant. Ceremony  is subjective to family's
wishes.

Be aware that the data shown by the free MarineTraffic.com website is
delayed by about six minutes.  Shipfinder.co is much closer to real
time. (I provide data to both sites, so I can compare the data I receive
with that shown on both sites.)

The AIS display websites depend on volunteers to gather their local data
and forward it to the website.

If you want real-time local AIS data, you need to have an on-board AIS
receiver.

Calypso was used to conduct a scattering of ashes at sea off San Diego in
1988.  The divorced parents of a suicide victim and a Navy chaplain were
aboard with me.  I proceeded to sea and turned off the engines at 3 miles
off Point Loma and lowered the flag to half mast.  The chaplain said the
words of the burial at sea service, and the ashes were scattered from the
down wind quarter.  A wreath was tossed into the water and the three of them
stood on the stern in silence for awhile watching it drift off.  After a
bit, when I considered a sufficient amount of time had elapsed with the
parents probably not knowing how to break from the service, I started the
engines and raised the flag to the masthead and slowly got underway.  In the
Navy, when we scatter a loved one's ashes at sea, the flag which flew at the
mast and a chart with an "X" marking the position of the service is mailed
to the family.
