How to Use the Ship Eez Sea Sickness Patch for Snorkeling
You’re dreaming of the vibrant reefs and incredible marine life of Kona, not a queasy stomach. The last thing anyone wants is for seasickness to crash the party. A Ship Eez sea sickness patch is one of our go-to recommendations—it's a simple, effective way to deliver medication through the skin for long-lasting relief, so your adventure is unforgettable for all the right reasons.
Your Guide to a Nausea-Free Snorkel Adventure
As guides for Kona Snorkel Trips, we've seen it all. And honestly, nothing dampens the excitement of a Hawaiian snorkel trip faster than that green-around-the-gills feeling. It's why so many travelers trust us—as the top rated & most reviewed snorkel company in Hawaii—not just for amazing tours, but for real, practical advice on how to have the absolute best time out on the water.
You don't have to take our word for it; see what our guests have to say:

So, Why Does Motion Sickness Happen Anyway?
It’s all about a sensory mismatch. Your brain gets confused when it receives conflicting signals from your eyes, inner ears, and body. On the boat, your eyes might be focused on the stable deck, but your inner ear is feeling the gentle rock and sway of the ocean. That's the conflict that can trigger nausea, dizziness, and that general feeling of ugh.
A Tip from Your Guide: Don't wait until you feel sick. Seriously. Prevention is a thousand times more effective than trying to cure seasickness once it’s started. Putting on a patch or taking something before you board is the single most important step you can take.
Finding the Right Remedy for You
Luckily, there are some great ways to keep seasickness at bay so you can focus on the amazing world under the waves. The right choice really comes down to your personal preference, how long you'll be on the water, and any medical considerations. The key is to be prepared.
For a really deep dive into all the options, you should check out our complete guide on how to avoid sea sickness.
Here are some of the most trusted remedies we see our guests use successfully:
- Ship-EEZ Seasickness Patch: This is a fantastic choice for multi-day relief. It's a transdermal patch that slowly releases medication, which is why it's a focus of this guide.
- Dramamine pills: A classic for a reason. These oral pills are fast-acting, but be aware they can make some people drowsy.
- Bonine pills: Another popular pill, often chosen because it’s marketed as being less drowsy than other options.
- Sea Band wristbands: A drug-free option that uses acupressure on your wrists to help with nausea.
- Ginger chews: A natural and tasty remedy. Ginger has long been known for its stomach-soothing properties.
In this guide, we're going to walk you through everything you need to know about the Ship Eez sea sickness patch, one of the best tools out there to make sure your snorkel tour is smooth sailing from start to finish.
Why Patches Are a Go-To for Modern Travelers
When you picture your trip to Hawaii, you're probably dreaming of snorkeling with turtles or swimming alongside majestic manta rays. The last thing you want is to be stuck on the boat feeling green around the gills.
That's exactly why the Ship Eez sea sickness patch has become a must-have for so many of our guests. It’s pretty much a "set it and forget it" solution to a problem that can ruin a perfect day on the water.
Instead of having to remember to swallow a pill every few hours, you just stick a small patch behind your ear. It works by sending a slow, steady stream of medicine (scopolamine) through your skin. This completely avoids that up-and-down feeling you can get with pills, giving you smooth, consistent protection from nausea.
The Power of Long-Lasting Relief
The biggest win for most people is how long they last. One little patch can keep you feeling great for up to 72 hours.
Think about it. That’s perfect for a Kona vacation where you might be doing our Captain Cook Snorkeling Tour one day and then heading out for the Manta Ray Night Snorkel the next. You put it on once, and you’re covered for the whole adventure.
This kind of discreet, long-lasting delivery system is becoming more common for all sorts of things—you can even find things like an ADHD patch for adults these days. It’s that same reliable convenience that makes it so amazing for preventing seasickness.
The numbers back this up, too. The global demand for scopolamine, the stuff inside the patch, was valued at USD 385 million in 2022. That huge number is tied directly to people like you getting back out there and traveling again, choosing easy and effective options.
Why It's a Smart Choice
For a family heading out on one of our boats to a spot like Pawai Bay, knowing a patch offers three full days of relief means less time worrying and more time making memories. This isn't just us talking; the trend toward simple, hands-free solutions is clear.
Key Takeaway: The best part about a patch like Ship Eez is its sustained-release technology. It provides continuous protection, which is far better at preventing nausea from ever starting than trying to treat it once you already feel sick.
This long-acting, barely-noticeable delivery is a huge reason patches have become so popular. While they are a fantastic medicated option, it's good to know there are drug-free alternatives out there. If you're curious, we have a whole guide on how sea sickness bracelets work.
But for powerful, consistent prevention on your Kona adventures, the patch is tough to beat.
Getting the Most Out of Your Ship Eez Patch
Nothing bums us out more than seeing someone's incredible day on the water get sidelined by that queasy, green feeling. We've been there. You've planned this trip, you're excited to see the dolphins or snorkel with mantas, and then sea sickness creeps in. It’s the absolute worst.
That's why we're big fans of the Ship Eez sea sickness patch. It's a game-changer, but only if you use it right. Think of it as part of your pre-trip prep, just as important as charging your camera or packing your reef-safe sunscreen. Getting the details right is the secret to a carefree day focused on the magic of Kona's coastline, not on your stomach.
The single biggest mistake we see, time and time again, is people putting the patch on too late. You can't just slap it on as you’re boarding the boat and expect a miracle. The medicine needs time to do its thing.

The Golden Rule of Timing
Here's the most important piece of advice we can give you: the patch needs to be on your skin for at least four hours before we leave the harbor. Seriously. Set an alarm on your phone if you have to.
If you’re joining us for a morning tour, this means putting it on the second you wake up. For one of our afternoon trips or the legendary Manta Ray Night Snorkel, lunchtime is your target. This one simple step makes all the difference between a fantastic day and a miserable one.
How to Apply It Like a Pro
Getting the patch on correctly is just as important as the timing. You want it to stay put through all the swimming and snorkeling fun.
First, find the perfect spot—that little patch of clean, dry, hairless skin right behind one of your ears. That's the sweet spot for the medicine to absorb properly.
- Give that area a quick wash with soap and water and dry it completely. Any lotion, sunscreen, or even a little sweat can keep the patch from sticking.
- Once you’re prepped, pull the patch from its little pouch and press it on firmly. Hold it down for about 30 seconds to get a really good seal.
- Most importantly, wash your hands thoroughly right after. The last thing you want is to accidentally rub the medication in your eye. Ouch.
A Quick Word of Warning: Please, never cut a Ship Eez patch in half. We've heard of people doing this to get a smaller dose, but it’s really unsafe. It can release the medication unevenly and cause much stronger side effects. Also, make sure you apply it to healthy skin, not on any cuts, scars, or irritated spots.
What to Expect: Side Effects
While most people do great with the patch, it’s good to know about potential side effects. The active ingredient, scopolamine, can sometimes cause a few minor things:
- A bit of drowsiness
- Dry mouth (another great reason to stay hydrated!)
- Some temporary blurry vision
These are the most common and they typically fade away once you take the patch off.
The FDA has also noted a rare risk of hyperthermia (overheating) when using these patches, which is something to be mindful of in our warm Hawaiian climate. On our trips, we're always encouraging you to drink plenty of water—it’s key to feeling great out on the ocean. If you start to feel uncomfortably hot, dizzy, or out of it, just let one of our crew know. We'll have you remove the patch and cool down in the shade. Being prepared is the best way to ensure you have a safe and absolutely unforgettable adventure with us.
Comparing Your Seasickness Prevention Options
One of the biggest questions we get from guests before a trip is, "What's the best way to not get seasick?" It's a great question, because nothing ruins a beautiful day on the water faster than feeling green around the gills.
While we're big fans of the Ship Eez sea sickness patch for its long-lasting, set-it-and-forget-it convenience, it’s not your only option. Finding the right remedy is a personal thing, and what works wonders for one person might not be the best fit for another. It's all about what your body prefers and what your trip plans look like.
It's no surprise that a whole industry has popped up to keep you feeling good on the water. That market is expected to reach a staggering USD 525 million by 2031, with scopolamine patches like Ship Eez leading the way. You can dig into the numbers in this motion sickness market research if you're curious!

Medicated vs. Natural Approaches
Your first real decision point is whether you want to go with a medicated or a non-medicated route.
Medicated Crew: This group includes the Ship-EEZ Seasickness Patch and classic oral tablets like Dramamine or Bonine. These use active ingredients to interrupt the confused signals between your inner ear and your brain that cause nausea.
Natural Navigators: If you'd rather skip the medicine, options like Sea-Band wristbands and ginger chews are surprisingly effective for many people. Sea-Bands use acupressure on a specific point on your wrist, while ginger is a classic, natural stomach-soother.
Medicated options are often the heavy hitters, but don't discount the natural stuff, especially if you're only prone to mild queasiness. We dive even deeper in our guide to the best sea sickness medication.
Breaking Down the Choices
Choosing what's right for you often comes down to a simple trade-off between power, duration, and potential side effects. To make it easier, we've put together a quick guide comparing the most popular choices.
Seasickness Remedy Comparison Guide
| Remedy | Type | How It Works | Pros | Cons |
|---|---|---|---|---|
| Ship-EEZ Patch | Medicated (Patch) | Scopolamine blocks nausea signals to the brain. | Set-it-and-forget-it for up to 3 days; very effective. | Needs to be applied hours in advance; potential dry mouth or drowsiness. |
| Dramamine/Bonine | Medicated (Oral) | Antihistamines block nausea signals. | Fast-acting and widely available. | Can cause significant drowsiness; needs to be retaken for longer trips. |
| Sea-Band | Non-Medicated (Wristband) | Acupressure on the Nei-Kuan point. | Drug-free; no side effects; reusable. | Effectiveness can vary from person to person; may not be enough for severe motion sickness. |
| Ginger Chews | Non-Medicated (Edible) | Naturally soothes the stomach. | All-natural; easy to take; can help with existing mild nausea. | Effect is short-lived; works best for mild cases. |
As you can see, the Ship Eez sea sickness patch really shines with its 72-hour duration. It’s perfect if you're planning a full weekend of Hawaiian adventures, letting you cover multiple snorkel trips with just one application.
A Guide's Perspective: We often see guests who love the patch because it’s one less thing to worry about. With pills like Dramamine, you have to time it right before the trip, and the drowsiness can be a real drag for some folks, making them miss half the fun.
On the flip side, a drug-free wearable like a Sea-Band is a fantastic choice if you want to avoid medication entirely, and you can use it again and again. And sometimes, for those who just have a few pre-boat jitters, a couple of ginger chews is all it takes to settle the stomach.
Ultimately, you know your body best. Think about how prone you are to motion sickness, how long you'll be on the boat, and your comfort level with potential side effects. A little bit of prep with the right remedy for you ensures your focus stays on the incredible marine life, not on a queasy stomach.
What We've Learned After Years on the Water
Putting on a Ship Eez sea sickness patch is a great first step, but we’ve picked up a few other tricks over the years that can make a huge difference. These are the little things we share with our guests—simple, practical adjustments that work with your patch or pill to keep your stomach happy.
After all, you’re here to enjoy the incredible Kona coastline on your way to the snorkel spot, not to feel miserable. These are our go-to tips for making sure you have the best possible day out on the water.

This advice comes straight from our crew, who live and breathe these waters on amazing adventures like our Captain Cook Snorkeling Tour. It’s an experience you really don’t want to miss.
Check AvailabilitySimple Strategies We Swear By
It all starts before you even step on the boat. We see it all the time—someone has a huge, greasy breakfast and regrets it the moment we hit the first swell. Keep it light! Toast, fruit, and yogurt are your friends. Stay hydrated with plenty of water, but maybe skip that extra-large coffee or pre-boat cocktail. Both can dry you out and make things worse.
Where you sit on the boat really matters. The ride is always smoothest in the middle of the boat, on the lowest deck. We try to steer folks away from the very front (the bow) or the back (the stern), where the bouncing and rocking are much more noticeable.
It's no surprise that motion sickness remedies are a big deal. The market for scopolamine patches, like Ship Eez, hit USD 419 million in 2023. Their long-lasting, non-drowsy relief is exactly what snorkelers and boaters are looking for. It's solid proof that these patches are a reliable choice, and you can see more data on why they are a go-to for travelers.
Pro Tip: Find a spot on the horizon and just lock your eyes onto it. This helps your brain match what you're seeing (a stable point) with what your body is feeling (the boat's motion). Trust us, staring down at your phone or trying to read a book is the fastest way to feel queasy.

Common Questions About the Ship Eez Patch
Even after you've decided to give them a try, it's totally normal to have a few last-minute questions about something like a sea sickness patch. We want you to feel 100% confident and ready for your day on the water with us. So, we’ve put together the questions we hear most often from our guests about using the Ship Eez sea sickness patch.
Can I Go Swimming or Snorkeling with the Patch On?
Absolutely! The Ship-EEZ Seasickness Patch is designed to be waterproof, which is exactly why it’s such a great choice for a day of snorkeling. The adhesive is made to stay put while you’re exploring Kona's incredible reefs.
The real trick is all in the application. You have to put it on a clean, dry, and hairless patch of skin behind your ear at least four hours before you get on the boat. This gives it the time it needs to really stick. Once you’re out of the water, just gently pat the area dry—no need to rub it.
What Are the Most Common Side Effects?
Most people find the side effects from scopolamine patches to be pretty mild, if they notice them at all. The big ones we hear about are:
- Dry mouth: This is super common. Just think of it as a helpful reminder to stay hydrated and keep sipping water throughout your trip!
- Drowsiness: Some people definitely feel a little sleepy. It’s a good idea to test one out on a lazy day at home first to see how it affects you before you commit to using it on your big adventure day.
- Blurred vision: This one is less common and almost always temporary.
These effects usually disappear pretty quickly after you take the patch off. It's worth knowing that, in very rare cases, more serious side effects can occur. In a warm climate like Hawaii, there’s a slight risk of hyperthermia (overheating). If you start to feel really unwell, take the patch off and talk to a doctor. For the vast majority of people, though, a nausea-free day is well worth the minor inconvenience of a dry mouth.
How Soon Should I Apply the Patch Before My Manta Ray Snorkel?
This is the big one. Timing is everything. You have to apply the patch 4 to 8 hours before your tour. We can't stress this enough—it's not a suggestion, it's essential. The medicine needs that much time to absorb through your skin and actually start working.
Take our famous Manta Ray Night Snorkel for example. Those tours usually leave in the late afternoon. The perfect plan? Stick your patch on right after lunch. Slapping it on in the car on the way to the harbor is one of the biggest mistakes we see people make, and it pretty much guarantees the patch won't have time to do its job.
Is the Ship Eez Patch Safe for Everyone?
That’s a really important question, and the honest answer is no. Scopolamine patches aren't typically recommended for children, for starters.
It is crucial to consult your doctor before using a scopolamine patch if you are pregnant, breastfeeding, or have certain pre-existing medical conditions like glaucoma or issues with your bladder or intestines. Your doctor can provide personalized advice based on your health history.
For families with kids or anyone who'd rather skip the medication, there are some fantastic alternatives. We see a lot of guests have great success with non-medicated options like Sea-Band wristbands or natural remedies like ginger chews. We go into a lot more detail in our article on seasickness and pregnancy. At the end of the day, always put your safety first and check with a medical professional.
Here at Kona Snorkel Trips, our entire goal is to make sure you have an unforgettable, comfortable, and safe adventure. Being prepared for seasickness is a huge part of that. If you still have questions, just ask! Our crew is always happy to help.
