This post is in response to the questions regarding good on board water. An article we wrote a few years ago and published in the AGLCA Great Loop Link newsletter titled "Potable Water For Long Range Cruisers" will explain how to obtain "bottled water" quality water on your vessel at a nominal cost and make purchase of bottled water while doing the Great Loop Cruise unnecessary. See the ARTICLES section of our website listed below: We learned however at the Atlantic City Boat Show that the lesser expensive Nature Pure unit has been discontinued and that in the future only the Sea Gull unit will be available (they will continue to manufacture filters for the Nature Pure). Also when filling the house water tanks from known "city" water which is chlorinated, don't use charcoal filters which will remove the disinfectants from the city water, but do keep them in line when filling from untreated well water.
