Actually a 60 watt load is a lot for a non switching regulator to do.
You don't want a switching type on a boat as it interferers with the radios.

I think your best bet is :

I have used this in airplanes with good luck before.

NOTE! USE a BIG heat sink!! it will get hot. If it gets too hot the device
will auto shutdown.

The NTE933 is not a good choice for this application - the minimum
input/output differential (AKA dropout voltage) is 2.6 volts - on a
car or boat 12 volt system, this means that the NTE 993 regulator will
only be working as a voltage dropper, and not as a regulator.

I think that the only solution for the OP is a switching regulator
that can both buck and boost the input voltage.
