Hey mates
I've been busy, just got back in here.... will try to answer as best I can.There seems to be a kinda senseless pecking here that is not seen on other sites where one fires at another to impress the group, often shooting himself in ones foot whilst doing it.Response sounds plausible and along with the laws of phiysics, if there is any leak ABYC wants it to vent out the bottom of the dedicated LPG locker, as opposed to CNG which is at the top corner of the dedicated locker.I do not make any of this stuff up, where is a motive?Here it is: Lockers used to contain LPG cylinders, cylinder valves, regualtaing equipment, and safety devices shall be designed to minimize the likelihood of use as a gear storage locker, and shall be,1.81.11) vapor tight to the hull interior, and1.8.1.22) located above the water line, and 1.8.1.3 constructed of, or lined with, corrosion resistant materials, and(BTW Hans C. and other yachts do have wooden LPG lockers on deck, okay)1.8.1.43) shall open only from the top with1.8.1.54) a gasketed cover that shall latch tightly, and1.8.1.64) shall be capable of being quickly and conveniently opened without tools.1.8.4 lockers shall be vented at the bottom by a dedicated vent, with a minimum diameter of any component in the vent system that shall not be less than 1/2 inch (12.5 mm) inside diameter.This is the ABYC standard manufacturers use, insurance companies, and when called into a court by the opposing attorneys in each case.Now go ahead kill the messenger....;-)I don't know of a link online for this, ABYC is non-profit, but much of thier income comes from classes and selling books and publications.
