I'm going to be putting the batteries under the cockpit floor on #66. A hatch (already purchased) in the cockpit floor will give access.

This is perhaps a bit higher and futher aft than some would find comfortable, but I'm rebuilding the whole interior--although not to the extent that Ebb is going to--so I'll be able to compensate for it.

More importantly, there is some significant unused space here, and I'll be needing the current battery location for the cooler.
