Hi John
Thanks for the reply.
The boat only has a single battery installed at the moment.
As part of the fridge install I want to add a second battery.
I wanted to add it in the same way Bavaria would have done had it been a factory fitting.

Were both batteries installed under the starboard seat?
Were they installed fore and aft?

Do you know where I can get the battery retaining fixings from?
