After a couple of weeks cruise up and down the NE coast I can now confirm from experience that the engine start battery is indeed isolated from the domestic stuff. After several nights at anchor, the engine start battery never dropped below about 13V whereas, after anchoring overnight with the anchor light and the Chartplotter on to provide the anchor alarm, the domestic battery was occasionally down as low as 10V.

Many thanks for all the good advice on this topic.
