Going to vomit?
Maintain medications and decide whether you need more, or different, medications.
To avoid going overboard don’t lean over the lifelines; use a two-litre plastic container with tight-fitting lid that you can use on deck and below.
Most people feel much better afterwards, but make sure you keep up your fluid-electrolyte intake. Take small sips, stay hydrated, and keep your blood sugar level up.
Repeated vomiting causes dehydration quickly, along with hypothermia (even in the tropics), anxiety, confusion, depression and shock. Once in shock, an enema or IV is the next step to rehydration and your survival.
After departure, coastal wave refraction and associated choppiness should be followed by more regular ocean swells, so do not be initially discouraged by seasickness. In almost all cases sailors recover from seasickness within 1-4 days if they follow the above advice.
Remember it’s your responsibility to do everything you can to get over, or help your crew get over, seasickness as quickly as possible. No one wants to be a liability onboard. Those who come through seasickness appreciate that managing it well is key to unlocking the pleasures of cruising under sail.
