I've been giving a lot of thought about how to secure the Engel in its spot. It has ranged from wooden cleats to barrel bolts to some incredibly complex metal banding that hugged the refer and gave us the ability to use several over center latches to draw it tight. Wow! Keep it simple! If simple lashings would hold a Wharram cat together, they certainly should hold a 50 lb. refer in place. We will replace the handles on the Engel with a couple of folding pad eyes that will allow us to run some 1/4" line through the lashing blocks and D rings.
This shot shows just how big the foot print of the MT35 is. You can also see the holes in the main bulkhead that will help the refer "breath". As much space as it eats up, there is still plenty of room behind it for galley storage.
