On a certain boat (that shall remain nameless) the propane cylinder is installed in an
anchor locker. That arrangement in itself is not too great, it limits the size of a cylinder, exposes cylinder and regulator and hoses to water and potential damage by chain/anchor.
However, there really aren't any other enclosed areas to install a propane locker - ABYC does not permit them installed in cockpit lockers or engine room (and rightfully so), and there isn't anything else.
Would it be wise/allowed by rules/work well to install the tank outside, say on deck in some sort of a holder attached to stern pulpit? Am I missing anything in considering this?
