Here are some tips:
– Take a homeopathic remedy like Travel-Med or a pharmacy medication like Sea Legs or Marzine (Note: any pharmacy meds need to be taken the night before travel)
– Eat an easy to digest breakfast (not muesli)
– Drink only half your normal cup of tea prior to leaving. Avoid coffee or alcohol
– Lean on something while at sea. Don’t try to balance yourself
– Look at the horizon not the movement of the boat
– Eat ginger snacks like gingernuts or crystalised ginger
– Drink very little until you are on the way home, sip ginger beer or ginger ale
– Keep busy with fishing or ask the skipper if you can drive the boat.
