Probably not - you have no way of cooling the fuel to the temp required to keep it liquid. It was our only choice - besides leaving the biz. When the liquid becomes gas it expands to 600x. CNG is more likely = 3600psi and can be quick filled. But you need to have a ready source at the marina - I can't see a tanker truck dispensing it. The alternatives are no better - barrels of DEF and/or scrubbers on the stacks.
