SkipperJer,
I have a Commander and can easily find the Bidge access 1, 2, and 3. I don't see an access hatch for #4. I have the model without the inboard...have an outboard in the well.

The batteries for my electrical system seem to be where access 4 is. I moved the batteries and don't see an access hatch. Do some Commanders not have that access point?

thanks, mike
