How do solo sailors sleep at sea? Experts share their tips and advice

Once I was planning my first solo offshore sail on my Lagoon 410 Cushla, from Grenada to Bonaire, my greatest concern was not the chance of pirates off the coast of Trinidad, or the night-time squalls which may sneak up unseen within the commerce winds. Even the chance of falling overboard and watching the boat sail away as I drifted alone within the present wasn’t giving me stressed nights. The priority I used to be shedding sleep over was sleep, and the way I might guarantee I’d get sufficient sleep when stewarding the boat on the four-night passage.

I do know I don’t operate properly when affected by a scarcity of sleep. I get irritable and make unhealthy choices. Extra particularly, I wrestle to distil the related elements from every part occurring round me when making very important choices. My forward-planning goes out of the window and my actions change into reactions to the obvious and instant elements. It’s not psychological state to be in when the flawed choice may be pricey, trigger harm and generally be deadly.

Coincidentally, the Grenada Hash, an orienteering occasion held weekly across the island, was helpful coaching. Throughout the first weeks of taking part on the run, I discovered the mixture of being bodily drained and having to make navigation choices very irritating, however over time I developed the talent of dedicating bodily power and time to pondering and decision-making. Practising that psychological shift was very helpful when drained at sea.

Brief naps when solo crusing

I do discover it simple and helpful to nap, and on the recommendation of a good friend I downloaded an app referred to as Interval Timer onto the boat’s pill. It sounds common alarms all through the day. I set this to go off each 15, 30 or 45 minutes, relying on the circumstances, however importantly I let it run day and night time so at any time when I felt I might sleep I’d simply lie down, realizing I’d be woken throughout the given timeframe.

With clear skies, no visitors and much from land I set it to an extended interval, and shortened it when circumstances modified.

I attempted to make life simpler for myself and simplify processes I’d have to do once I knew I’d be drained by making checklists on post-it notes caught across the boat.

Gas your self correctly

Meals and water are necessary components for getting good sleep. My sleep is gentle and fitful on an empty abdomen, and my choice making can also be affected once I’m hungry or dehydrated. I made positive I had easy accessibility to water with bottles dotted across the boat in simple attain. I didn’t drink espresso, and as a substitute of brewing a cup of tea at any time when I felt sleepy, I’d simply take a nap.

I created a giant snack basket that lived within the companionway containing blended nuts, biscuits and fruit, and I saved chocolate within the fridge to present me an power hit at any time when I felt foggy or torpid. I additionally made a behavior of cooking meals upfront that might simply want reheating or could possibly be eaten chilly from the fridge.

Muddle-free sleep zone

Having a snug place to sleep additionally helped. I discover it tempting to share the mattress with no matter muddle I can’t be bothered to place away, however I put a mattress within the cockpit and saved it away from mess to take away distractions from sleep. Away from an web sign it was simple to withstand the temptation for display time when mendacity down.

An eye fixed masks additionally helped delay sleep at daybreak, and made it simpler to fall asleep in the midst of the day. I developed a Pavlovian response to the snugness of the masks which helped set off a deep sleep at any time when I grabbed it and put it on.

Energy is instrumental

In addition to holding your individual batteries charged, the boat batteries additionally have to have dependable cost. As the facility drains, the autopilot can change into unreliable, disconnecting at low voltage. Cushla, our 1998 Lagoon 410, has 1kW of photo voltaic panels and though we will, we’ve by no means wanted to cost the home batteries from the engines or shore energy. However in a single day passages are the hardest check of the system.

The sails can create shading on the panels for a number of hours of the day, and working the devices 24/7 is a major drain, particularly the radar which might draw three or 4 amps when working, and even attracts a few amps when in standby mode.

The boat has an AIS transponder, and offshore I felt fairly assured that different visitors would even be transmitting an AIS sign to fireplace my proximity alarm. Radar is beneficial for recognizing rain squalls at night time or when low cloud masks approaching rain.

I made the error of not studying easy methods to set the proximity alarm on my Raymarine C80 chart plotter upfront, and once I got here to do it for the primary time, I discovered it frustratingly unintuitive. Lesson realized; change into acquainted and practiced with the menu capabilities you have to earlier than setting off.

Don’t put issues off

If something was niggling on my thoughts it could cease me falling asleep so I’d make sure that to take care of something that would trigger me anxiousness; tidying the traces, checking the course heading, and a ultimate, gradual 360° sweep for visitors or climate. Choosing a climate window the place squalls can be much less probably and utilizing a modest sail plan that was simple to handle additionally decreased my anxieties.

I felt exhausted as I lastly pulled in to the moorings of Bonaire, however not as drained as I assumed I’d be. The satisfaction of self-reliance, finishing 440 miles solo, and the reference to the ocean I skilled alone offshore are all highlights of my time as a solo skipper, and the sail will stay a formative expertise.

Jean-Luc Van Den Heede’s solo sailor sleep recommendation

Jean-Luc Van Den Heede holds the report for the quickest westward circumnavigation, crusing it solo, quicker than any crewed boat. He’s 77.

‘I at all times attempt to sleep sufficient. I sleep for 90mins and wake to verify every part’s okay, and if there’s a job to do, I do it. Or I’m going again to sleep. ‘In 1991 researchers measured my sleep cycle with 16 electrodes over two days. Folks checked out me humorous going round city with wires on my head.

‘However that’s how they got here up with the 90-minute determine. I do it even when I’ve crew. It actually works for me.

‘I can wake instantly and be capable of do something in two seconds. It’s a attribute of mine, but it surely’s developed over time crusing alone. It wasn’t like that at first once I began my first solo navigation. Now I can sleep at any time. In three to 5 minutes I’m sleeping, even at three within the afternoon. I simply shut my eyes, empty my head and that’s it.

‘In lengthy races just like the Golden Globe Race it’s good to have relaxation, and good sleep. At all times make sure your thoughts is okay. The principle drawback on the GGR, was when the wind shifts, the boat modifications heading.

‘In the event you’re cruising offshore, in the present day with AIS alarm and a windspeed alarm, you’ll be able to sleep a very long time. 4 hours isn’t any drawback. However if you happen to’re near shore, it’s a must to be awake due to fishermen and crusing boats with out AIS.

‘It’s necessary to remain optimistic. In the event you’re afraid of one thing you can’t sleep. It’s higher to be in fine condition on the finish of the storm or low stress, so it’s necessary to have relaxation earlier than, and to not be drained when the wind is powerful. I attempt to sleep in the beginning of storm, and to be in fine condition when it’s within the ultimate section.’

Laura Dekker sailed around the globe solo aged simply 14. She now teaches younger individuals ocean crusing and private improvement.

‘I’m at all times very aware of each motion I tackle board; each sound, each motion – something unusual. I strive to not bounce to conclusions earlier than trying out all of the elements.

‘If I’m very sleep disadvantaged my mind form of fogs up and issues undergo my thoughts a lot slower then regular. However I do take heed to nonetheless undergo the entire course of earlier than making a call and never simply bounce forward as a result of it’s taking too lengthy.

‘I sleep once I can, it doesn’t matter what time of the day or how lengthy it might be, together with plenty of 10-minute naps. I’ll at all times put relaxation and sleep forward of something “enjoyable” I’ll have had in thoughts, so it goes forward of studying or taking part in music, for instance.

‘By no means assume “Oh I’ll sleep later,” if you happen to can sleep now. Issues change in a short time at sea and there’s an opportunity it’s possible you’ll not be capable of sleep for a very long time.

‘Set a number of alarms for which it’s a must to get off the bed to show off. It’s simply too simple to sleep via or go to sleep once more.

‘There’s typically solely a have to verify round rapidly in between naps, so sleep for 30 minutes, get up, verify the horizon, course and sails. At night time, shine a torch round your rigging – this takes about 10 minutes, then sleep one other half-hour.

‘The longest I ever slept in a single stretch is one hour, that’s with clear visibility on open sea. Large ships journey between 15-20 knots. Visibility at sea when it’s good isn’t any extra then 10 miles, so in concept, in half-hour you’ll be able to go from not seeing it to being run over. Higher to get up extra typically and verify rapidly then return to sleep. Near shore this drawback will get worse as there are sometimes little boats with minimal lights that may solely be seen from a mile.’

What the scientists say

Whenever you’re asleep you cycle via 4 phases of sleep. Three non-REM phases (N1, N2 and N3) and REM sleep. The primary one, N1 is nodding off, the second is getting ready you for deep sleep, and N3 is the place the mind, bones and muscle groups absolutely loosen up and do their therapeutic and get reset for the subsequent interval of wakefulness.

In N3 you might be hardest to wake and might even sleep via loud noises or the boat jolting. In case you are woken from N3, it’s possible you’ll really feel foggy for as much as half an hour. REM sleep is a lighter stage of sleep but it surely’s while you dream. Your physique immobilises itself so that you don’t bodily act out these desires.

Throughout an uninterrupted night time’s sleep most individuals cycle via the 4 phases each 90-110 minutes.

Analysis printed in 2007 confirmed being sleep-deprived results in riskier choice making and a extra blasé angle to issues going flawed.
