We seem to average around 1.2 mpg with KAMD43's cruising around 22-24kn, but we are very heavily loaded. Best we ever got was 1.4 to the gallon. Anyway, at 1.2 mpg it comes out to around 80 l/h like Jez said.
-------------------- The nicest thing about not planning is that failure comes as a complete surprise, and is not preceded by a period of worry and doubt.
