Have just read a fascinating article on fuel cells for marine small boat use. It seems the way to go for the future. One difficulty at the moment is the restricted availability of the methanol fuel cartridges.
Does anyone have any personal experience? Or any views/comment?

Hi Tony,
I am sorry for your troubles and thank you for sharing this information. It may help to convey to the manufacturer that you are going public with your frustrations, but it also may not. You underscore a position I take when thinking through equipment for offshore venturing vessels to never be an early adapter: let offshore equipment have 5-10 years of use.
Let us know how things unfold.
