Medically Reviewed. Strategies to Prevent Motion Sickness Here are some ways you can reduce the risk of becoming seasick: Be well rested before setting sail. Missing sleep and feeling exhausted make you more susceptible to factors that can cause motion sickness.
Wind down before your trip. Talk to you doctor about which medications are best for you, as you may be limited by other medications you are taking. Antihistamines can cause drowsiness and dry mouth and eyes. Because antihistamines block messages to the part of the brain that controls nausea and vomiting, taking a medication such as Dramamine works best if you take it before you get motion sickness.
So for best results, take the pill before you board the ship, if you're going on a short trip. Get fresh air. If you are feeling seasick, it is often helpful to go out on an open deck or balcony and look toward the horizon.
Doing so helps your eyes "see" the motion, which will then send signals to the brain more in alignment with what the inner ear is "telling" the brain, Bradberry says. Fresh air, especially wind blowing in your face, tends to help. It also helps to focus on something other than the boat's motion, so try to keep active while aboard the ship. Request a cabin mid ship and near the water line. You might also want to request a room with a window or portal so that you can easily look out on the horizon.
Have a bite. The best foods are light and bland, such as saltine crackers, plain bread, or pretzels. Having some food in your stomach is better than having an empty stomach, but be careful not to eat too much. However, pitch can be a challenge, and just as for heave, the pitch is reduced as the boats get larger.
But luckily, the effects from pitching can easily be countered by where you position yourself onboard. As a captain, I was very conscious about where I placed the guests onboard. Pitching is something you per definition experience in the bow — or at the stern of the boat, depending on the vessel type and cruising speed. This is where you have the most significant movements, and this is where you see the largest acceleration up or down. So, if you make sure that your guests stay midships, you rarely have any problems.
This is also why you usually find the owner's cabin positioned in the center of the boat. So, if you want to avoid getting seasick, stay away from the bow or stern in heavy sea. Heavy rolls also increase the risk of fall injury for the guests and crew. To avoid seasickness and the risk of injuries for its passengers, cruise ships have been using stabilizers for a long time.
Over the last decades, stabilization technology has become a "must-have" on superyachts and yachts down to approximately 60 feet. There are many options to choose from on the market — and they work very differently, so make sure you do your research before you decide which technology to put on your yacht. This might very well be the most important part of the boat's options list in addition to air-conditioning perhaps.
There are different systems designed to reduce roll onboard a yacht left: gyro, right: vector fin. They work differently, and it is very important that you choose the one best suited to your usage of the boat. When a boat is rolling from side-to-side, the rapid and constant acceleration of the head from side-to-side has a significant risk of making most people seasick. How much, and how the boat will roll, depends on the length and size of the waves and the overall stability of the boat.
Luckily for boaters, this rolling effect is something we can almost eliminate with today's technology, and compared to the cost of a yacht, it's a relatively small additional cost. The graph shows how a boat's roll angle can be significantly larger than the actual wave angle. This is a consequence of the boat building up a rolling momentum as it rolls, and this is also why if you can , you should always choose stabilizers on board a yacht.
This rotation is called yaw. For comparison, in a car that follows a road that just keeps on turning, this "yaw" effect is what often makes passengers carsick, but as boats rarely need to follow the turns in the same way as a car, the effect is usually a lesser source of seasickness. We do have some advantages at sea! Worth mentioning regards yaw though, is that a side-effect of some of the stabilization systems on the market is that they create a bit of additional yaw.
The yaw effect is considerably more significant on flat fins than on Vector fins. In either case, this side effect, when it comes to eliminating seasickness, is compensated by the stabilizer's ability to reduce roll and dramatically increase overall comfort and safety onboard.
As mentioned at the beginning of the article, it is repeated accelerations that make us seasick. Hence the yacht's constant movement forward or backward does not make us seasick. Sway is uncomfortable, and you might have experienced it before on trains riding on uneven tracks. The sideways movement of the train has an impact on overall comfort and can contribute to motion sickness. Onboard a yacht with fin stabilizers that generate too much sideways movement, you can experience a touch of sway.
How much the stabilizers will move the boat sideways when they counter the roll from the waves depends on the shape, size, and positioning of the fins on the hull. Flat fins, notably positioned towards the center of the boat, creates a significant sideways force. My colleague, Ronny Skauen, has written an in-depth article about the various stabilization systems for yachts and what you should consider when selecting yours. You can read the full article here. In short, there are a few different systems that dominate the market today, and we will look at the pros and cons of the most popular systems below:.
On a yacht without stabilizers, rolling make the balance center of a person's head move fast from side to side. On a stabilized yacht, the movements will typically be reduced by more than 80 percent.
Since the rolling cycle will be the same, the acceleration, which is what makes us seasick, nearly disappears. If you mostly use your boat at anchor, you can safely choose any of the three dominant systems on the market today. They will act a bit differently, but in principle, you will probably be quite happy with their performance, and seasickness at anchor will be a problem of the past. Like everywhere else in the world, however, there is no "perfect" system.
Flat fins have a reputation for causing some forward movement of the yacht in very light wind or current conditions, Vector Fins have the same challenge although less because of their curved shape. Gyro's are less efficient than fins when cruising. Some manufacturers of flat fins have countered the swimming effect by their ability to turn the fins backwards hence swimming away from the anchor , but generally speaking, this challenge was more of a problem on older systems.
Today the algorithms controlling the fins have become more advanced, and fins no longer "swim the boat" the way they used to.
The Vector fins generate much more stabilizing forces than flat fins — and because of their shape, they have significantly fewer side effects. That is why they are trusted by some of the world's leading yacht producers today for stabilization at any speed.
If you use your boat a lot for cruising, there are big differences in the various stabilization systems available on the market today. Here, you really need to pay attention to what kind of system you're putting into your boat. You need to know that where gyro stabilizers are restricted by only having a constant force available to stabilize the boat, the stabilizing forces of fin stabilizers increase immensely as the speed of the boat increases.
If you have a good understanding of physics, you will know that the forces vary by the square of the speed. Hence, at speed there can be huge differences between the stabilizing forces of a fin system and a gyro.
If you have read this far, you probably understand that I am biased in this discussion. I have the privilege of working for the world's leading manufacturer of fin stabilizers for yachts and have a personal interest in promoting the Vector fins. What is a rogue wave? What do leeward and windward mean? Here are a few tips to help ease the symptoms of seasickness: Maintain your fluid intake. Seasickness and related medications cause dehydration and headaches.
Drink water, low-acidity juices like apple and carrot, or clear soup, and avoid milk and coffee. Keep moving.
