Kind words Rick. Thank you. 

The guy who fabbed the tank said he has installed tanks both ways with success so I am not terribly worried about it.

Your concepts and implementations are smart.  Looking good Koz!

The piers are 4 inch squares of left over Coosa from the transom laminated together with a layer of mat in between each layer. I used 4 pieces of 1708 on each vertical plane of the pier after I bedded the piers in thickened resin. The "horns" ar to keep the tank from moving forward. They are mostly gassed in. I'm not finished. Probably will give another layer of 1708 or 2 all around. Where the tank's dog ears (?) mount to the stringers I have added 3 more layers of 1708 or will. There will be a total of at least 5 layers of 1708 plus multiple layers of mat. Should be pretty stout

I have a 2003 Aquasport Osprey 205 that has developed a sound under the console in the hull that is amplified when going over waves. It sounds like a creaking/rubbing sound. We have checked out all the access ports, the T Top mounting screws, and have visually inspected what we could in hatches and under the floor but don’t see anything obvious. It is hard to really see anything even with a horoscope camera. Obviously trying to rule out anything structural and am guessing will need to cut into the floor to gain better visual? Just looking for any suggestions on what to look for or what it possibly might be. Has anyone experienced this before? Might it be a cracked stringer? I have tried to move the fuel tank and shake the t top and console but they seem sturdy.
