There is really no specific way.
If you know where the
boat is moored you can call the harbor master and leave a message for the owner, or send a letter.
All depends on the willingness of the vessel to be found. If they have an
ais transponder you can see where they are, but you still need to do the legwork to contact them.
When I take off on the
boat I make it a point to not broadcast my whereabouts, it's more peaceful that way.
