Worthington Tanks

I have a question concerning propane tanks and marine surveys for insurance.

My present propane tank is in the starboard cockpit lazarette. I am concerned about adequate ventilation and, as always, saving space. I would like to mount a new tank on my stern rail and a the best I have seen is a Worthington 6-lb vertical tank.

My question is: Will this "pass" a marine survey for insurance purposes?

Thanks in advance.

David

Re: Worthington Tanks

You don't have to have the propane tank mounted for a survey, mine wasn't. My propane locker is in the port side lazarette but it is currently being used as a tackle storage and we use the small camping propane canisters.

When I had my survey done this lazerette was just empty and the survey just stated that there was a locker available.

If you had a proper rail mounted holder....and wanted to ensure that it was notated on the survey...I don't see why it would hurt any.

Plus....talk to your surveyor, they will let you know and if it is a problem I am sure he/she will allow you to remove it before the survey is done.

Re: Worthington Tanks

The rules are fairly simple
If you mount the tank outside in the open it must not be above any openings into the boat including vents and windows.

All systems Must have a regulator, a shut off valve that can be remotely operated at the appliance (stove)
A gauge must be installed before the regulator. (to test for pressure leaks)
The supply line must have no breaks, meaning a single line run the whole length, no splices or other connections.

lockers must vent overboard, be air tight and top opening.
All common sense really and USCG requirements so its the law

See my article (as published in Cruising World) on propane systems here: Project Boat Zen - Maintaining your Propane system

Any questions let me know

Re: Worthington Tanks

oh and any surveyor who would allow to remove the tank prior to the survey so the system will "Pass" is not helping you any in fact they could be putting you in harms way. these rules are to protect YOU not the insurance company!

Below all vents? How an I supposed to accomplish that, I'd have to mount it below water off the stern? I under stood that outside the aft rail(above water) was ok? Proper fittings sensors etc included of course.

I'm on an alberg 30 if that helps, currently Re doing my propane system adding solenoid sensors etc.

Nobody said the tank had to be below all vents... you can't mount a tank directly above a vent or window. Propane is heavier than air, you don't want your tank leaking and most if the gas going down a vent into your quarter berth

Thanks,I misunderstood must not be above any openings then that makes life simpler again. Any min distance horizontally to openings lower than tank?
