We discussed this three months ago and I have been working on it since. The cooking fuel on our Frers 33 and on a friend’s Sabre 34 as well as a number of other boats manufactured in the 1980s was Compressed Natural Gas (CNG). We have a gas distributor in Nova Scotia (Heritage Gas) that supplies large CNG bottles to commercial customers where they do not have pipes to supply natural gas. They do not have a consumer refilling side.
I have found that since our boats were purchased in US (and built there) the CNG canisters we have are DOT certified (which is US only) and not CTC so have no Canadian certification. In order to have refilled they need to be certified in Canada and then we need to find a place to have them refilled. One option is to purchase new tanks the same way we do for propane. The reason I am sticking with CNG and not converting to propane is that I do not have a propane locker. CNG is lighter than air and does not require one. My only option for Propane would be to hang a tank off the pushpit, modify the gas lines to reach it and modify the oven to accept it. Refilling the tanks is a much more attractive option. I have purchased the boat CNG refill adaptor that Joe mentioned below. I also have an idea where I may be able to refill a tank and I have managed to find one Canadian certified tank. All of that was a three month long endeavor. I then had an idea. Surely it is possible in Canada to purchase a new tank of the correct specifications that is certified bot Canada and US. It must also be possible to have this filled as a normal course of business thru one of our regular gas and tank supply companies such as Praxair or Air Liquide. Does anyone on this list have experience with where to purchase these tanks with the appropriate valves and who would fill them? The alternative would be to drive to the nearest place that exchanges these tanks which I believe is Camden Maine. That is a 12 hour driove and involves transporting gas canisters over an International border … Thanks Mike Persistence Halifax, NS From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Della Barba, Joe via CnC-List Sent: Monday, March 21, 2016 3:10 PM To: 'cnc-list@cnc-list.com' Cc: Della Barba, Joe Subject: Re: Stus-List Stus-CNG tank refills The tanks is a modified SCUBA tank. 1100 PSI is about just under half full. They are usually about 2200-2400 when topped off. You need to go on FleaBay and look for an adapter to hook your tank up to the CNG station to fill it. They hold about $4 worth of gas. Your other choice is to find a marina that does CNG tank exchange for about $100!
