As a professional. charter capt for 35 years, world wide, have found that some remedies work for one person , but not another . Some no mater what they do, nothing works.

But, as Breeze stated, in addition to the motion sickness remedy, there are other things that you can do .

1. Lay off the Booze the night before . Also, no over abundance of any liquid. Especially, coffee, tea, fruit juices especially, orange juice, or any other liquid acidic liquid. , .

2. Have a healthy breakfast , or meal before you go out sailing. A couple of cups of coffee and a pastry, donut, etc, is almost a guarantee for spending the passage feeding the fish.

3. Stay up top side, and do not go down below. Especially if blowing chunks . Lean over the stern or a down wind quarter, have some one grab tightly to the back of the sick persons belt. Secures them from toppling overboard and they know that they are not
not going to lose their balance . Have a wet towel for them to wipe off their face and what ever.

4. Absolutely, put them to work, at the helm, at the beginning, steering the vessel, also looking out at the horizon, or land . Give them a job to concentrate on.

5. Follow the directions of the particular medication, and take it well ahead . Waiting until the person feels queezy or uncomfortable is too late.

6. Do not sit around in the cockpit telling BARF stories or bragging about sea sickness experiences.

7. For shorter passages or trips of a couple of days, I used to recommend that the scopolomine patch be cut in half, to reduce any unwanted physical effects. That patch goes on the neck.

I have heard stories using all kinds of mal de mere prevention. with just about everything, from wristbands, to the patch, to ginger, to bonine, and nite nite dramamine , etc. Some times the work, and some times the do not work.

If, the motion sickness is a true condition, and nothing seems to stop it....THAT PERSON DOES NOT BELONG ON A BOAT, ESPECIALLY ON A WEEK OR TWO SAILING TRIP IN THE BVI. Not a good plan for everyone on board to be around a poor
retching soul,. That can make others on board sick as well. The fun light will be extinguished, period.
