the supermarket in las palmas
(hiperdino?) sells the 6liter mineral water jugs,but buy them when you find them as they do run out with so many boats provisioning
at the same time.
we also carried 200l in 25liter containers in the cockpit
for showers and refilling the main tanks with the dinghy
when on anchor
is also set up with a permernantly rigged rain catcher making it just a case of putting a hose in an empty container during squalls.
turning off the pressurised system is a must,i once on a delivery
where a hose came off and emptied the main tank into the bilge
overnight!,the automatic bilge pump
dumped all 1000 liters overboard
without us noticing!
ideally salt water
showers on deck
,with a cup full of fresh to rinse off keeps the crew happy.
a salt water
foot pump at the galley
makes short work of the dishes.
a hand pump for fresh water for cooking and boiling the kettle will ensure water usage is minimised.
wet wipes are great for freshening up if the weather
also if you like wine which is expensive in the carib you can buy the 1liter bricks of table wine in las palmas
for about 80 cents a liter,worth stocking up!
