I read that a SeaRey that had landed with the gear down in the water had the Battery Tray pull off the Hull and break the leg of the Pilot. I figured with 2 batteries, I better add more fiberglass to the tray attachment. Now I have to come up with a way to tie down 2 batteries and keep them together in ruff water.
Added fiberglass on top and underneath the Plywood
Got 2 more straps to hold the 2nd battery and tie the 2 batteries together
