Propane box
Is this good practice or are there real regulations? I wonder why a box is needed for a bomb proof steel pressure container anyway. The real risk is the hosing and other downstream attachments.

Real regulations.
ABYC A-1 is attached, section A 1.12 addresses your question directly. The USCG adopts ABYC A-1 in 46 CFR §184.240(a) making the provisions federal law.

The box is as much for controlling gas leaks as protecting the tank

What Joe said.
Propane is very similar to gasoline in that vapors are heavier than air meaning in the event of leakage they'll settle into an explosive pool in the bilge and the energy is only slightly less but comparable to gasoline. Propane storage tank pressures can range between roughly 30 to 200 PSI. Typical on board regulators are single stage that reduce the tank pressure to less than 1/2 PSI.

Another thing - you cannot use a propane box INSIDE a boat. We got a propane job where the owner wanted a box inside the boat. We warned him, but did as requested. I did say we needed a surveyor to sign off to keep us from getting sued if he blew himself up.
The surveyor said no way no how and we then built a teak and stainless mount to keep the tanks on the stern rail overhanging the water. We got nice aluminum 10 pound bottles and it ended up looking OK. |

minimal propane storage
A la one of Don Casey's books, I built a pvc tube with a sealed capped bottom end and a removable pvc top lid. It perfectly holds three one lb canisters stacked. It attaches to the stern rail, and has a 1/4" hole in the bottom of the outboard edge to vent fumes.
