Update take 2:
Since I'm doing some work to reinforce some stress cracks to the hull floor as well as put in my new pod seat I've noticed that the floor of my searider is a composite sandwich of gelcoat, fibreglass, some kind of fiber core, then fiberglass (from the top down). I was drilling some holes and noticed that there is in fact a core of some sort but its not wood. Its almost like a fibreglass packing that hasn't soaked resin or something. I have yet to call Avon but I think I'm forced to now out of curiosity as well as concern for water intrusion.
I also noticed that the bolt plugs are just that, plugs. There aren't fixed stainless steel bolts under each plug. I assume this hull was cast and to conserve on bolts Avon only put SS bolts under the plugs they were going to mount the drivers center console too. So now I am going to revert back to using self tapping screws and Silkaflex to mount the pod to the floor. Maybe for the consumer version of the Searider they put SS bolts under each plug but not on mine. Just an FYI.
I will try to post some pics later.
