If you test a battery aboard a boat and it reads only 12.6, it is not
fully
charged.
Fully charged to "float phase" is over 13 volts for flooded batteries and
13.7
for gel cells.

With the float charger attached, agreed.
Remove the float charger for an hour or so and the voltage for a fully
charged flooded battery will be 12.6 volts.

Been that way for many, many years.
