lazarette

Good afternoon all! New member of the forum and new owner of a 1991 Hunter 27. I was wondering if anyone had any insight on accessing the lazarette on this series H27? The aft hatches are relatively small accessing this space. Is there an easier way of geting to the fuel tank and batteries...

It just occurred to me that a nice aftermarket part for the C30 Mk1 would be an aft lazarette door with a raised seat for the helmsman. It would add extra space in the lazarette while providing a seat. I assume nothing like this is out there, but what is everyone else doing for a helmsman seat? -P
