What an interesting and useful thread this has been!
When I referred to a three stage charger in my reply to Nigel, I was
thinking of the shoreline scenario, leaving the boat permanently
connected whilst it's sitting in the marina.
On Sanity Again I *think* we've decided on a large output solar
array, not with any expectation that it will do all the charging we
need, but so that we can tie for a couple of days in the summer and
not have to run the engine, and be able to leave the boat to visit
relatives and so on without having to either find a shoreline
connection or else turn the fridge off.
I take the point that a good quality charge controller is essential,
as well as the Smart Gauge to help keep track of the state of the
batteries.
All the best
Bruce
