On Badger, we carried our kero in 20l containers in lockers in the lazarette. A small hand pump was fitted and I used to pump up the kero into a jug to transfer to the cooker and lamps. A similar system would work well with alcohol, especially if you are buying it already in 20l containers. But they would have to be jerricans, rather than pails. In later years we found that it was difficult to buy kero anywhere, particularly good quality stuff, so were pleased that we had this bulk storage. Equally, if you were sailing in the Islands, you might find it worth stocking up with alcohol in advance. For the sake of interest, I use about 2.5l alcohol per week, cooking for myself - I do a lot of 'real' cooking rather than just 'hotting up' food.
While I agree with David that alcohol is a great fuel for voyagers, I cannot, alas, say that the cookers available are equally great. Other people seem to get on OK with the Origo, although David has found it slow, but the 'gimbals' for the stove are apparently useless. The Maxie is a faster cooker, but the burners corrode and it, too, has useless gimbals. I have managed to obtain a pressure alcohol cooker for SibLim (and am working on getting another, for spares), but as far as I can tell, the burners are no longer made. I find this very strange as these are surely the ultimate cooker: fast and clean using an easy-to-stow liquid fuel. Admittedly, you can apparently get a spectacular fire if you don't light them correctly, but lighting one is not exactly rocket science.
