BTW, how much pressure in the cng tank of a Hunter 40.5. It currently reads 1100 psi. Not sure how long it would last?
Doesn't matter what boat it's on.
"Nominal" pressure is 3000, Steve just reported in his last reply that it may have gone up to 3600, right?
1100 psi for a 3000 psi tank = ??? You could do the math, right? The pressure is linear to the amount left.
How long? Geez, how much do you use it?




Really. If you're living aboard compared to using the boat once a week and making a cup of coffee. Only you know that.
I keep track of when I last refilled/replaced. My experience is six months, average, over the past 17 years. When I use my boat weekly and anchor out for one or two nights.
When I go up to The Delta and live aboard, less. When the boat is hauled and things are being replaced and I'm not out sailing/cooking, more.
Good luck.
