I made up medical kits for hundreds of voyagers in the 30 some years I was in practice. I strongly advise any voyager to first contact their own physician, and discuss their plans, have appropiate tests done, before leaving, proper immunizations, and have the appropiate prescriptions for the drugs aboard. Drugs aboard need to be specifically taylored for the perticular crew of that vessel. I have always wondered how a pharmacy can legally dispense medications without a physicians prescription? It can be dangerous as well as illegal. Also giving medication to both crew and other voyagers is frought with some danger, because of adverse reactions. Also know what the medical problems of the crew are. I know of several deaths on voyaging pleasure vessels where crew members have died at sea, because they should not have been making the voyage, and the skipper had no idea what medical problems were involved. I have given out lists of what a comprehensive medical kit should contain many times in the past on the various forums. An excellent book, which should be aboard all voyager's vessels is "The ships Medicine Chest and Medical Aid at Sea" Fortunately the 2003, (most recent edition) is available on line free: http://www.fas.org/irp/doddir/milmed/ships.pdf This is a publication of the US public health service. Other books I find to be of help are: Paul Gill: "The Onboard Medical Guide: First Aid and Emergency Medicine Afloat ". :Wilderness Medicine, Beyond First Aid". AMA first aid book or American Red Cross First Aid book. Merc Manual, PDR or "The Pill Book" Paul Auerbach, Wilderness Medicine (Wilderness Medicine: Management of Wilderness and Environmental Emergencies) Carl Weil has a good blog on wilderness medicine: http://blog.wildernessmedicine.com/ Finally The Society of Wilderness Medicine is a group dedicated to improvement of medical care for people who are in remote areas. http://www.wms.org/ Although this is mostly for first responders, it would be very wise for at least two people aboard the vessel to have first responder capability. The minimum would be CPR and advanced first aid. Better yet is a EMT course. Bob Austin
