I didn't like the location of the propane lockers and wanted more room below. I removed the lockers and sealed off the holes. Both sides will get a 10" access port and I'll build a storage compartment on the port side. the starboard side hatch will give me access to the autopilot equipment and storage.
The tanks will be stored aft above the coaming in brackets that will be part of the radar arch.
These pictures show the sealing off of the locker openings.

In brackets at the arch is definitely a safer location Mine are in the lazarette which is not terrible-but your working reminds me to go through the locker and make sure the drain is clear and all openings are sealed up.
