Sea sickness.....
They say the only real cure for sea sickness (Mal de mer) is to sit under an apple tree… on land… that doesn’t move!
Most people who spend time at sea will suffer from sea sickness at some point. Some actually suffer the reverse of ‘land sickness’ too! We all have a story about that one time when…! Humans have fought against sea sickness for all time. Ancient Greeks called it the ‘plague of the sea’ and famous sufferers include Admiral Horatio Nelson and Christopher Columbus. Charles Darwin once wrote ‘The misery I endured from sea sickness is far, far beyond what I ever guessed’ and ‘if it were not for sea sickness, the whole world would be sailors.
Symptoms include: nausea, vomiting, dehydration, headache, dizziness, muscle spasms, drowsiness, lethargy, excess saliva, sweating and burping.
So what causes this debilitating, incapacitating infliction for which there is no cure?
In simple terms, it’s what happens when your inner ear balance system reacts to the unfamiliar motion of being on water. It’s the same reaction that causes car, or any other kind of motion sickness. The movement of the vessel you’re on causes the fluid in your inner ear to slosh around and this stresses the part of your brain that handles balance. The signals the brain receives are telling it that the things you see, such as walls and furniture should be still. But, on a boat, everything is moving constantly, including you. The air, the sea and everything on the boat is moving. This confuses the brain and nausea sets in.
Battling through sea sickness can be helped by pharmaceuticals, psychology or nature. For the lucky ones, it will often disappear after a couple of days as your brain adjusts to the ever-moving environment and your ‘sea legs’ develop.
Our instructor Rachel and her rowing partner Lin, decided not to take any medication for their Atlantic row. Both suffered sea sickness in the first 36 hours with nausea and vomiting. They did find that lying down or rowing were fine, it was just anything in between that caused a problem! But it passed quickly and they were fine for the rest of the voyage. Interestingly, Rachel now suffers from mild land sickness and often feels dizzy and a little nauseous after even a short time on the water.
In addition to the inner ear, other factors that can contribute to sea sickness include blood flow, heart rhythm, hydration, sinuses and psychological factors such as excitement, nerves and fear.
Mind over matter can work for some. One sailing instructor is reported to tell students that if they hold a potato in their left hand they won’t get sea sick! Bizarrely it works for most and if you’ve ever had sea sickness, you’ll most likely give anything a try!
Some common triggers for sea sickness include:
- Hydration. Avoid alcohol and stay hydrated. Even if you vomit repeatedly, try to drink in between as it can ease the nausea and you will absorb some.
- Food. An empty stomach, or eating spicy, fatty or acidic food mean that your stomach is more likely to react badly to any nausea. Vomiting with something in your stomach is much better than vomiting on an empty stomach.
- Fear. Even in difficult conditions, try to stay calm. Anticipation of being sick can bring it on and being ill just adds to the problems.
- Temperature. Extreme cold or heat can cause nausea. Try to adjust your layers according to the temperature and be ready for temperature changes.
- Fatigue. Make sure you and your crew are well rested before departure. Plan shifts to allow for illness.
Sea Sickness Remedies
- There are many drugs available that can address the issue so it’s best to speak to a Doctor or Pharmacist to find the right one for you. But , it’s worth remembering that many drugs suppress the symptoms of sea sickness, so while they are ideal for a day sail, may not be as effective if you’re at sea for longer as symptoms can still happen if you stop taking them.
- There are also lots of non-medical remedies such as acupressure wrist bands, patches, and sea glasses that might be worth a try.
- Avoid dehydration and muscle spasms by staying hydrated before and during your voyage. Avoid alcohol if possible. Have drinks handy at all times including bottles of water in the cockpit.
- Eat. Even if you vomit it back up - it’s better to have something in your stomach. Ginger is recommended - ginger biscuits, ginger snaps, ginger tea, raw ginger, ginger sweets or ginger ale. Peppermint can help, or even a small amount of toothpaste on the tongue can ease the nausea. Rachel recommends tinned fruit in syrup on the basis that it goes down (and up!) easily and the glucose in the syrup helps keep energy levels up. Eat things that will taste the same on the way back up and not leave a yukky taste in your mouth, for example, an apple versus tuna or dairy products which could add to the nausea.
- Try to avoid strong smells such as diesel, the head, the galley.
- If you start to feel nauseous, distract yourself. Take the wheel or carry out a task that requires concentration. Stay on deck in the fresh air if possible, and focusing on the horizon can help your brain to figure it out. Standing or lying are better positions than sitting.
- Lie flat in the centre of the boat where movement is reduced. Avoid the bow. Sleeping on the floor instead of a bunk can reduce motion.
- Try to sleep and rest when you can, even if you don’t feel tired. Sleeping onboard the night before departure can help your brain to figure out the motion.
- Try the trick with the potato in your left hand! Mind over matter can work and it will give the rest of the crew something to laugh about!
- If fear is a factor, try not to let it take over. Trust your skipper and crew, the boat and yourself. Reassure yourself that things can work out well. Research before setting off can help.
- Focus on the positives. The things you love about being out at sea and the things that make it enjoyable for you.
- Plan shifts and allow for illness. Think about the skill mix of those onboard and shortening shifts if necessary.
- Prepare meals in advance if it’s likely to be rough, so you can grab food on the go and minimise time below deck.
- Challenge yourself with a goal, such as trying to make every watch, to provide a sense of achievement even if you’re feeling rotten.
- Use something solid to provide balance, keep your legs shoulder width apart and offset the boat movement with your body - like using a hula hoop.
- If you know you’re prone to sea sickness, accept it might happen and focus on the things you know will help and how you’re going to fight through it to calm your nerves and fear.
Finally, if you are going to be sick, make sure you head to the down wind side!!!
In basic first aid classes, there is great emphasis on not moving a patient under any circumstances. But is this always right? Our Paramedic friends tell us about times they have arrived on scene to find an elderly faller virtually held down onto the icy ground they slipped on because they think it’s best. Or a care home resident who is unharmed, wriggling around but just unable to get themselves off the floor. Of course, if the person is ill or injured, care must be taken to prevent the condition from worsening, but certainly in our maritime environment there may be times when we MUST move a patient for both their and our safety and wellbeing. We may even need to move them into a safe space (such as lowering from height) before we can assess them and work out the potential injuries and associated risks. But how do you know when to move them? Or how to move them safely? Here are some situations where moving the patient might be essential: Immediate danger – if the patient is in immediate danger, and if it’s safe for you to help, they should be moved away in some manner. This could be due to fire, an unstable structure, in the water, an otherwise unsafe location. Cardiac Arrest – the patient must be on or moved to a hard, flat surface in order for compressions to be effective. Ideally with a bit of space for a team to work around them. To prevent further harm – if the patient is in a position where they could worsen, or something life threatening could develop, you may need to move, or at least reposition them. This could be due to vomiting, choking on blood, unable to maintain their own airway and could be as simple as sitting them up or rolling them over. Self-extricate – if the patient is able to self-extricate, they should do so. There has been a lot of recent research into this area and old techniques challenged and changed. For instance, in a road traffic collision, if the patient can get out of the car themselves, they should. You can find out more here: https://phemcast.co.uk/2022/09/15/extrication/ Worsening conditions – if the weather and environment change, then you may need to move your patient. For illness or injury, keeping someone warm is important, if not vital. Even in a tropical climate, a trauma patient can cool more rapidly than you think and those rain squalls may pass quickly but do a lot of soggy damage in a short time.
At the time of writing, the Caribbean superyacht season is in full swing and the Mediterranean season is looming just around the corner in a few months time. It can be a stressful time for any crew, from the most senior to the most junior - and we could all do with a little help to manage stress and our response to it. We’ve written a number of blogs about mental health and things you can do to help manage your own stress and mental health, and when to seek help. We’ve listed them at the end of this blog. But did you know that we can also offer a one day, onboard training session, for the whole crew? Stress Happens! is run in conjunction with the super experienced team at Impact Crew, so you benefit from a business, leadership and team perspective, together with the medical and wellness input. Stress Happens! was developed in response to feedback from superyacht crews and has been running for 4 years. It can be delivered in one day and is suitable for crew at any level. It’s also delivered onboard, making it easy to facilitate the whole crew to attend. The aim is to focus on mental wellbeing and stress, providing tools and techniques to help you to manage your own stress, helping others to manage their stress and knowing where to turn for help if it’s needed.
In this month's blog, as aching hearts aren’t just related to Valentines Day, we’re taking a look at chest pain! Chest pain is a common reason for calls for an ambulance or to shoreside, and frequently it’s not actually due to cardiac (heart) issues. But you will often hear Paramedics tell their patients that they have done the right thing; they would genuinely prefer to get to a patient and find the chest pain is a minor issue, than it being cardiac, and too late! Last year, we wrote this blog about 20 causes of chest pain (plus a bonus one!). Some of the conditions described are acute (sudden onset), some are chronic (long term), some need urgent attention, others not so much. But we should always take chest pain seriously and make sure a full assessment is done at the earliest opportunity to rule out anything life threatening. Typical symptoms of cardiac chest pain and/or a heart attack are:

From Flu jabs to far flung destinations… Vaccinations are a hotly debated topic across the globe, particularly after COVID-19 and the rapid response to the need for a vaccination to help reduce the burden on the health services in different countries. While the majority of healthcare workers and the general population support the ‘prevention is better than cure’ line of thinking, and therefore vaccinations, there are others who are determinedly against vaccinations for any disease, whatever the risk of mortality and death may be. In the UK, the BCG (Bacillus Calmette-Guerin) vaccination used to be given to all children in their teenage years to protect against tuberculosis. The vaccine has been so successful that TB is virtually eradicated now, and the majority of cases are due to migration. Now it’s only given to those deemed at high risk - babies and children at high risk, those travelling to high risk regions and adults coming into the UK from high risk countries. Depending on your country of origin, you should receive a range of vaccinations as a child or young adult. This will most likely include diphtheria, tetanus, polio and whooping cough, hepatitis and HIB (Influenza type B). Then MMR (measles, mumps and rubella), the pneumococcal vaccine (meningitis, pneumonia and sepsis) and HPV (Human Papilloma Virus) with a variety of boosters along the way. At the other end of the scale, the over 65s can receive vaccines for shingles, pneumococcal vaccine and respiratory syncytial virus along with flu and covid vaccines.
Reflection is an essential part of medicine and our regular followers will know that every year, we like to take a look back and assess where we started and how far we’ve come over the last 12 months. So, please join us on our whirlwind recap of 2024 as we get ready for a fabulous 2025… In 2024 we increased the number of STCW training clients to 4 organisations in 6 locations. We delivered STCW training at all levels to over 250 students. We delivered bespoke training to over 75 students onboard Superyachts and cruise ships. We delivered first aid at work or oxygen training to over 40 students, on land and on ships.
Welcome to our December blog, which is all about the recovery position and how to manage an unconscious casualty who is breathing normally. Unconsciousness is a medical emergency as the person is very vulnerable and may not be able to manage their own airway effectively. We also need to think about the cause of unconsciousness. Is it a simple fainting episode due to illness? Is it a massive hemorrhage causing hypovolemic shock? Or is it due to some kind of external factor or injury? This blog looks at how to manage an unconscious casualty. So, if we have a casualty who is unconscious, but who is breathing normally for themselves, and we’re not suspecting a serious injury, the recovery position is the best position to use while monitoring them. The recovery position keeps their airway open and makes sure that vomit or liquid won’t cause them to choke.
All the guest blogs! When we started adding blogs to our website back in early 2021, we did a little feature on each of our instructors of the time. They’re quite a fascinating bunch and the series proved quite popular amongst our followers. In addition to our amazing instructors, we work with some utterly incredible human beings all over the world, and the idea of sharing their stories grew and developed into what eventually became a monthly guest blog. It’s been interesting to find out more about how medical care at sea or in remote locations features in their work, and to discover a few fun facts along the way. This month, we thought that it might be a fun idea to give you a chance to go back into the archives and review all the guest blogs over the last few years! Maybe even let us know which your favourite one is?
We’ve taken a look at the 2023 Casualty Summary Report from the Maritime Authority of the Cayman Islands (MACI) to see what kind of incidents and trends their data shows us, even with relatively small data sets, and how this may be able to transfer to our own risk assessments and actual practice. You can find the report here: Cayman Maritime Report 2023 The first thing we noted was the authors note that the data is split out into incidents. This means that one incident may include a number of events. So a collision and any resulting injury is one incident, but is reported as two events, or more, if more than one person is injured. It made us wonder whether this method of reporting by an authority represents how incidents are reported onboard and whether it should be a consideration? Of course, for any set of statistics presented at the moment, we also have to consider the COVID-19 pandemic and the impact this has on trends including that period. While essential shipping continued, the cruise and superyacht sectors reduced activity and staffing, often to a skeleton crew while anchored somewhere. So this will be reflected in the historic data sets that we analyse from 2019 to 2021 and may not accurately reflect increases and decreases during and since then. In some situations, we may need to look further back for accurate data. We also need to consider whether increases in incidents and events is also down to increased reporting - suggesting an improvement in the awareness of reporting requirements and greater engagement from the industry and individual sectors - this can only be a good development. Since 2020, the type of injury has been recorded in 8 different categories, with hand and foot injuries topping the leaderboard, closely followed by head, body, and back injuries. So if you were looking to run drills, or practise medical skills, these would be the key areas to cover. Only one death was an occupational accident, and is being investigated here: MAIB Investigations (search for case #9229607). It relates to a fall down a ventilation shaft on a bulk carrier in a Greek shipyard. The full report was still pending at the time of writing. Merchant ships are heavily regulated by a number of authorities, and the requirements for personal protective equipment and safe systems of work are enforced and applied to reduce accidents and incidents onboard. This has led to a lower reporting of incidents than in the commercial yacht sector. Could there be room for improvement here in this area? We certainly think so. Many of the hand and foot injuries reported can be career ending or life changing, but are preventable. Follow up has shown that there is a link here with injuries being sustained when inappropriate or no PPE was used. The supply and use of appropriate PPE is mandatory on vessels subject to the MLC and it’s worth remembering that some PPE can be produced in styles and designs compatible with the aesthetics of a yacht if required! On a much wider scale, a lack of transparency and standardisation globally can affect the collection of data and the issue of under reporting. While the MACI figures may be accurate, we need other accurate figures to compare them to, in order to build a bigger picture across the world as we have in aviation. From December 2024, the Maritime Labour Convention (MLC) will be enforcing an amendment so that seafarer deaths will be recorded and reported annually. The MACI and Cayman Islands Shipping Registry produces a number of safety flyers that are publicly available HERE that may be useful. In summary, analysing data can sometimes result in more questions than answers. But even this can lead to interesting and important developments that result in improved safety and reduced incidents and accidents onboard. Key points to take from this report are: Use the correct PPE for the task. Employ approved systems of work and risk assessments for the task. Reporting is key for safety in the future of our industry. Enjoy a night ashore, but don’t over do the cocktails! As always, if you’d like any input on medical training onboard or ashore, or drills that you can run yourselves, please just get in touch.

Welcome to our latest guest blog where we’ve been chatting to James Griffiths, General Manager of Ocean Operations for Scenic Group and finding out more about what happens behind the scenes in order to keep a fleet of luxury expedition ships running. Here’s what James told us… As General Manager of Ocean Operations, I’m responsible for the operations of our fleet which includes four ships in service with around 850 colleagues. I currently live in Mumbles, near Swansea in the UK, but due to the nature of my work I spend a significant amount of time living in Croatia. Prior to this role, I spent many years working at sea and worked up through the ranks to Captain and over the last 15 years, my main focus has been on polar expedition travel. I hold a master mariner certificate of competency in addition to a degree in engineering and a post graduate diploma in law. Part of my job is to work with our medical service provider (Red Square Medical) to ensure that our ships are offering medical services that are appropriate for their deployment, and this can often be to some of the most extreme and remote locations around the world. It’s extremely varied, though during the COVID-19 pandemic, I came ashore when our operations paused for a significant period of time. I was fortunate enough to be given the opportunity to lead the restart of our Ocean Operations, which included setting up everything from a company to manage the ships, to selecting our crewing, medical, helicopter and submarine partners and providers, amongst many other things. Our areas of operation, and the nature of our cruises (expedition), plus having aircraft and submersibles onboard some, do mean additional elements involved in the management of these ships. You could say that this current position is more of a happy coincidence than one that I actually planned for! In some ways this is a great positive - I do think it’s possible to plan a little too much and then be disappointed if things don’t go quite the way you had imagined. But there’s no danger of that here!
