Interested in a discussion oriented towards people who are looking to
live aboard, of ways to safely heat a cruising sailboat at dockside.

The boat I sail on (50ft. LOA) has small central heating radiators, just
like the ones you have at home, with a hot fresh water system, heated from
an Eberspacher hot water heater (very tiny). The system is fully
programmable, and although we don't live aboard in the winter, she's as warm
as toast when we are working on her. Keeping the heat on 2 hrs and off
4hrs, night and day, seems to cost very little, and the batteries are kept
charged by the marina's supply thru an auto charger.

So far, no problems. This is the 4th year since installation.
