"I will definitely need wood or
diesel. Just trying to understand the practicalities between the two."
An
oil fueled
diesel heater or range like a
Dickinson can be turned on in October and turned off in May after the
water warms.
A wood
stove may or may not be large enough to accept fuel that will go 8-12 hours so you are trapped on board , or the fire goes out.
The heat output is about the same, near 20,000 BTU for an
oil range which will keep you warm as it cooks or bakes .And a hot beverage is always a delight.

AS it takes time to light the oil fired ranges and for them to come to temperature , live aboard's use them all winter and simply plop a 2 burner stove (propane or kerosene) on top for warm
weather use.
No electric required if fuel is gravity fed.
