Also, from Dragged Aboard by Don Casey,
The best place for propane tanks is on deck
. If you want them out of sight, the locker you put them in must be vapor tight and separated from the boat's interior
. It must open only above deck
and have a drain at the bottom to let leaking gas escape over the side. Be sure the drain outlet is not located near any other hull
opening and that it is always above the water
, even when the boat is heeled. Aluminum
tanks are more suitable for the marine environment
. As a rule
of thumb, expect to use about 1 pound of propane per person per week cooking
three meals a day. So a full 10-pound tank should last a crew of two at least 5 weeks.
How big does the tank need to be?
A general rule
is that a person will consume 1lb. of propane per week for cooking
meals. 10lb. of propane will operate an average stove burner for 43 hours. That translates into three meals a day for eight people for eight days or two people for about 40-50 days. Propane water heaters use about 0.5 pounds per hour of operation. Tanks are available in either rust free aluminum
or powder-coated steel
. The American Boat and Yacht Council (ABYC) is the world's most highly respected boating
industry technical organization, and sets voluntary standards for boat construction and safety
in important areas like ventilation, electricity and plumbing
. While not mandatory, we recommend that you follow ABYC guidelines so your installations are safe and because the systems should work better. The initials ABYC refers to either the group itself, or the standards that the group establishes.
ABYC Requirements for Onboard LPG Systems
- Propane Lockers: isolated, vapor-tight and above the waterline with ventilation directly overboard
- Tanks: made of corrosion-resistant materials with overfill protection devices (OPDs)
- Pressure Gauges: installed in-line to detect system leaks
- Solenoid Valves: required for remote shut-off if the tank valve is not within reach of the appliance
- Supply Hoses: corrosion-resistant flexible tubing must provide a continuous connection to the appliance
- Dedicated Vent: located at the bottom of the locker with a minimum 1/2" dia.
- Warning Sign: with safety instructions located in the immediate vicinity of the cylinder
