Carry the fuel or fix the ATC.
Understandable sentiment bm330, but the sad truth is that nothing will change until we cause pain and headaches for the bean counters.
Clearly, the many hour delay waiting for a 10 min ferry causes you much more pain than carrying the fuel, but what causes more pain for the accountants? Is it the occasional cost of a ULH diversion, or the cost of the extra fuel?
Not being a bean counter, I don't know the answer to that. My semi-educated guess (reinforced by the DFO's comments) would be the extra fuel on a ULH. On a regional, a diversion would probably be more of a headache (read "cost") than the extra fuel. Medium haul (Aust/M.E./India), who knows.
I suggest you adopt the "punish the bean counter" fuel policy.
