bilge heater question

[jrcinnh]

At the risk of looking stupid...

Is there any reason to consider a bilge heater in addition to normal winterization? In my climate, with the possibilty of power failure, I would never skip fully winterizing. But I do have access to power all winter, would a bilge heater buy me anything?

I can’t see the embedded picture; guess I will just have to use my imagination on this one..
