Great seamanship: Taken by the wind


Tom Cunliffe introduces and extract from Taken by the Wind
Memoirs of a 1970s pacific voyage, which reveals a time when sailors had to rely on their own pilotage skills for safe passage
 
From YachtingWorld by Tom Cunliffe



Mike Jacker is a retired orthopaedic surgeon living in Illinois.
Among many other activities he still sails his boat, now mainly on Lake Michigan, but he has a long memory.
In 1976, shortly after graduating from college, he and two friends set off in a Cal 30 production yacht from New Orleans for a year’s cruise in the South Pacific.

The unusual thing about his account of this voyage is that it was not written until 2020, looking back on a different age with all the wisdom of a life fully lived.

I sailed away into the blue myself at the same time, and I find his notes on the total lack of backup, no weather forecasting, no GPS and no communication with the outside world, ring absolutely true. Nobody sailing with all the benefits available in the modern world should forget that, just one lifetime ago, things were very different indeed.

We join Mike and his shipmates leaving Belize, bound on a tricky traverse to Panama…

Taken by the Wind extract


On 15 September 1976, we cast off Rhiannon’s dock lines and cleared the mud bar at the mouth of Haulover Creek.
We were officially destined for the Panama Canal Zone, conservatively estimating arrival within two weeks.
We had already learned from experience that potential calms, equipment failures, and headwinds precluded overly optimistic predictions for any passage.

In letters mailed from Belize to our families back home, we even added a few extra days to our estimates.
We never wanted relatives to believe that we might be overdue in port.
If we did not contact them when they expected, we feared that perhaps they might initiate some sort of search for us; we were already dealing with enough angst of our own without any added concerns about someone launching an unwarranted search.

We never filed any sort of float plan or formal itinerary. In most places we were travelling, no organised search agency or rescue authority even existed.
Louis, Clark, and I knew that we were always alone, dependent on our own ingenuity and the limited resources of our fragile little boat.

A quick glance at any map or nautical chart of the Western Caribbean immediately reveals the most prominent coastal feature.
The eastern point of land in Central America where the Coco River forms the border between Honduras and Nicaragua, is a cape known as Cabo Gracias a Dios.
When voyaging south­ward along the Central American coast, one must travel eastward against the prevailing contrary wind and current to pass this formidable promontory.

The name, meaning ‘Thanks to God’, is attributed to Christopher Columbus.
On his fourth voyage in 1502, coincidentally also during September, Columbus required 29 days of rough sailing to reach this cape from Trujillo on the northern Honduras coast.
He endured horrible storms and endless headwinds before finally turning south into fair weather.
The passage was so miserable, even for the great ‘Admiral of the Ocean Seas’, that he gave thanks to God for rounding this point of land. Louis, Clark, and I were not bold explorers, but we fully understood the reputation of Cabo Gracias a Dios and girded our loins for the impending battle.

Our course took us toward the south-east after passing the south end of Turneffe Island. Cabo Gracias a Dios lay some 325 miles away.
We remained well offshore of Glover Reef, attempting to make as much easting as possible.
We then continued south on a port tack in moderate south-east winds.
On the second evening I noted that ‘we saw a magnificent rainbow, a meteor that lit up the area as day… and several flying fish landed on the deck’.


Clark and Mike sailing in the Marquesas

Later that night we tacked back and forth, rail down, as we were struck by intermittent gusty squalls packing 35-knot winds.
Rhiannon punched into the steep waves.
Despite the slog, we only made 10 miles of easting all night. During that night, we spoke to a nearby freighter by radio.
They provided a favourable weather forecast for the next day.
This was welcome news, especially considering our disheartening progress.

The following day we reached the Bay Islands of Honduras: Roatan and Guanaja. In the distance, a rain squall including a waterspout was drifting away, leaving us in fair weather.
With our track leading directly toward the gap between the two verdant Bay Islands, we held our course, cautiously avoiding the shoals east of Roatan.

That morning the sailing was perfect!
The sea was absolutely calm, the air was warm, the skies were clear, and the islands looked magnificent.
We saw no other people or vessels, even as we later tacked toward the east, following the south shore of Guanaja.

Paradise islands

This was our first taste of enjoying an idyllic paradise all to ourselves.
Our thoughts turned in awe to the feats of the early European explorers who, amazingly, had sailed through these same waters, without even a chart.
We had no clue of the tourist playground that this virgin region would become in the following decades.
I noted in my journal that if severe weather were to crop up over the following days, we knew of a place where we could easily return to seek shelter.

After passing the Bay Islands, we continued to tack eastwards, experiencing rain squalls alternating with calms.
On the short-wave receiver we were able to pick up the Caribbean weather forecast from Miami relayed through a repeater on Swan Island.
Thankfully, there were no storms predicted for the following three days.

On September 18, during one of several rain squalls, Clark suddenly called out, “What was that?!… I just saw a huge dorsal fin.” Louis and I wore eye-glasses, so could see little through our rain-covered lenses and even less with our glasses removed.
Nonetheless, I also soon spotted our visitors. It was a pod of small black whales.
Their smooth, sleek backs repeatedly broke the surface as close as 10ft from our starboard beam. Although we could not identify them at the time, these most likely were pilot whales.


Rhiannon at Bora Bora

They disappeared as quickly as they’d arrived.
We sighted no other whales during our time in the Caribbean.
In 1976, populations of the great whales had become alarmingly small, as most species had been decimated by the whaling factory ships prowling the oceans at that time.

Unlike whales, dolphins were more abundant in the 1970s than they are today.
Over-fishing had not yet critically depleted their food sources.
Dolphins have always been man’s greatest companions at sea.
They consistently thrilled us whenever they arrived.

Sometimes solitary but usually in groups, dolphins loved to play around the bow wave, dive beneath the keel, and perform acrobatics while keeping pace alongside the boat.
I was always delighted by the random appearance of dolphins during my night watches.
Frequently, I would be alerted unexpectedly to their presence by the characteristic breathy ‘puh-heee’ sound of a dolphin exhaling and inhaling as it broke the surface.
Soon others would join the first one, cheering me through my night watch.
Often, the lively underwater chatter of a pod would reverberate loudly through Rhiannon’s resonant hull, waking the off watch as well.

During this passage, I became acutely aware of the pelagic birds, the flying fish, and the leaping tunas, as well as the playful cetaceans that entered our world.
In truth we were the strangers invading their world, aliens to the sea.
But, occasionally, other members of the land-based world also paid us a visit.
Fishing boats frequently appeared and disappeared over the horizon as we neared coasts.
Aircraft contrails occasionally crossed the sky.


Rhiannon in the Panama Canal

However, to me, the most notable visitors were the ones who, like us, were most removed from their own element.
I easily empathised with the shore birds that had been lost or blown off course, ending up at sea.

I imagine that those birds, not accustomed to long overwater migration, would often meet death in the waves as soon as they became exhausted.
A few were lucky and found Rhiannon, the witch, transporting her own ‘three birds’.

Off the coast of Honduras, just beyond sight of land, on September 18, two small land birds came aboard.
One was a finch, and the other a smaller yellow-throated bird.
They walked over Clark as he lounged in the cockpit and took turns exploring the cabin.
As we tacked back toward the coast, they swiftly departed the moment land was in sight.
These visits aboard our floating home were always magically uplifting.

Storms avoided


Fortunately, we never met the fierce storms and daunting conditions described by Christopher Columbus.
However, consistent east winds forced us to tack back and forth repeatedly.
All afternoon on September 19, we could see a headland that we had hoped was the fabled cape.
But as we drew near, the contours of the coast and alignment of the shore informed us instead that this was Cabo Falso, the ‘false cape’ that had given Columbus false hope of having reached the true eastern promontory.

Beyond Cabo Falso, with 21 miles left to Gracias a Dios, we tacked to within 100 yards of the beach just before sunset.
A lone man was walking at water’s edge along the calm seashore.
Even though we’d been sailing for four days and were so close to the Honduran coast, we did not land.
As darkness fell, we cautiously came about onto starboard tack to head back offshore.
As long as the wind blew, we needed to continue toward Panama without stopping.

We then faced our greatest navigational dilemma thus far.
The sky had become overcast, and the wind had backed slightly to the north-east at about 15 knots.
This wind was perfect for a night rounding of the Cape.

However, there were no lighthouses, buoys, or other aids to navigation.
The charts indicated multiple areas of shoal water inshore, as well as many small reefs and islets, called Miskito Cays, extending well offshore from the Cape.
A cloudy sky prohibited celestial navigation.

Coastal piloting without any visible landmarks on shore would have been impossible in the dark.
We knew that dead reckoning using the compass would surely be helpful.
But strong, uncharted currents of uncertain direction precluded safe rounding of the Cape using only the compass and sumlog.
Unfortunately, the nearest radio beacons were scores of miles away.

Therefore, we carefully studied the charts to consider our alternatives.
One plan would involve sailing far offshore, bypassing all the hazards near the coast. But that would add a full day to our trip.


The sailing attire of the time protects against squalls
 
Following the contours

Just then I saw another possible way forward.
I ran my idea past Louis and Clark. A contour line on the chart denoting a depth of four fathoms (24ft, or 7m) described a broad, meandering arc that rounded the entire Cape while threading between all the obstacles.
The north-east wind would enable us to navigate the entire passage, sailing on a comfortable reach. We all agreed this would be our plan.
Next, we confirmed that our depth sounder was functioning properly.
Just in case the depth sounder might fail, we readied our lead line as a backup.

The flashing red dot on the face of the circular depth sounder indicated we were in 50ft of water.
We eased the sails, falling off toward shore.
Slowly, the bottom rose toward Rhiannon’s keel as we met the shallow water.
At just under 25ft, we intercepted the imaginary four-fathom contour line and adjusted our course.

For the next four hours, all three of us remained vigilant on deck.
We passed several unlit fishing stakes but otherwise kept well clear of hazards, as we walked a virtual tightrope between the prominent point and the treacherous reefs.
Once we had successfully passed Cabo Gracias a Dios, feeling immense relief, we set our course offshore, toward Panama. Louis, Clark, and I had accomplished in days what had taken Columbus weeks.

ArcticInfo ‒ A digital service for safer seaborne voyages in the Arctic


From Framsenteret by Anders Røeggen // BarentsWatch and Anne Grethe Nilsen // Norwegian Coastal Administration

ArcticInfo provides important information on sailing conditions in the Arctic, supporting decisions for safer navigation in Arctic waters.
Map-based and accessible to all, ArcticInfo covers large areas off the coasts of Norway, Iceland, Russia, Canada, and Greenland, plus the Barents and North Seas.

Low temperatures and extreme weather conditions, limited daylight over long periods of time, limited communication and infrastructure, poor charts, and large distances are some of the challenges that navigators face in Arctic waters.
On top of this, there are almost always very limited resources nearby if accidents occur.
To strengthen maritime safety and protect the environment, the Norwegian Coastal Administration has gathered voyage-related information in one place: ArcticInfo, available via BarentsWatch.

Users must register to get full access to the service, though much information is available without registration.
Registered users can edit data about their own vessel, such as maximum speed, ice class, gross tonnage, rescue capacity, communication capabilities, helicopter deck, and a doctor/nurse onboard.
 
 
 The actual framework of the service is the map, which shows a number of layers of data that the user has easily accessible.

ArcticInfo provides information about icebergs around Greenland, icing, ice concentration from the Meteorological Institute in Denmark and Norway (drift ice and solid ice), storm warnings for Norway, Canada, Iceland, and Russia.
Weather stations and ship information based on AIS (Automatic Identification System) from the Norwegian Coastal Administration are included.

“We want to offer a regularly improved service that can support navigators in making well deliberated and safe choices along the way,” explains Jon Leon Ervik, Head of the Department for Navigation Technology and Pilotage Management at the Norwegian Coastal Administration.

Maps showing the ice edge, wind, current and temperature, depth curves, quay conditions, and Norwegian maritime borders are included in the service.
You will find an option to send your voyage plan digitally to the Greenlandic authorities.
 
A user-based service

Since its launch in early 2020, ArcticInfo’s user group has proven to be very diverse.
A starting point for the service was the increasing cruise traffic prior to the Covid-19 pandemic, but fishing boats, the coast guard, and research and expedition vessels have used the information service.

Taitsianguaq Olsen is a marine pilot based in Nuuk, and co-owner of the company Imaq Pilot.
In addition to pilot assignments, they offer services for mariners in relation to the Polar Code and a service for yachts and other larger recreational vessels.

“I use ArcticInfo to check vessel movements in the waters around Greenland,” says Olsen.
“Depending on the time of year, I use the function ‘Ice concentration’ to see the ice edge in the map.”

Olsen hopes to use the service more when cruise ships can once again sail along the coast of Greenland, hopefully from next year.

Terje Solberg Johansen from the Joint Arctic Command in the Faroe Islands says they use ArcticInfo as a supplement to other navigation equipment onboard their vessels.
“We especially use it in connection with AIS to see which vessels operate in the Faroese fisheries zone 200 nautical miles from the baseline and to the border to Norwegian waters. But, most of all, we use the service to see Danish navigation warnings for our area.”

The Faroese Command is based in Mjørkadalur on Streymoy.
It is the command authority of the Danish Armed Forces under the Danish Navy Operative Command. In addition to safeguarding the sovereignty of the Danish Commonwealth, they also carry out tasks such as fisheries inspection, search and rescue, medical transport, and other public service tasks.

The Arctic Monitoring and Assessment Programme (AMAP) is an international organisation that is now part of the Arctic Council, and aims to obtain information about the status of and threats to the Arctic environment.
“Together with many other partners, we carry out environmental assessments of the consequences of climate change in the Arctic Ocean. In this work, it is important for us to know how many and what types of vessels use the area,” explains Mario Acquarone at the AMAP Secretariat.

For the Norwegian Maritime Authority, ArcticInfo is also a useful tool.
“I plan on using the service to observe ship movements in the polar region, and to identify the conditions in areas where ships operate,” explains Port State Coordinator Bjørn Ove Hansen, who works with Port State Control.

Through the project “the Nansen Legacy”, Charlotte Stark, from UiT The Arctic University of Norway, uses ArcticInfo actively to encourage the public to follow the research vessel Kronprins Haakon on an expedition in the Barents Sea.
“We want interested parties to follow the vessel and see where it is. When scientists are on important missions in the Arctic, we share this information with people who follow the project, including on Facebook. We have tried to find a suitable service that could show the vessel in real time and came across the service from BarentsWatch, which is also easy to use,” says Stark.
“It’s nice to be able to follow the research vessel in an interactive map, which is available through the BarentsWatch service.”

Jon Leon Ervik greatly appreciates feedback from users.
“Our objective was to create an information service that provides navigators with important and useful information that supports safer voyages for navigators in the High North,” says Ervik. “The feedback we have received so far not only confirms that we are on the right track to that end, but that the service is also useful for others. Even though we have broad expertise that contributes to good decision-making in the Norwegian Coastal Administration, it is the feedback from users that ‒ ultimately ‒ will enable us to develop and deliver good services.”
 
Will further develop the service

The Danish Maritime Authority was to develop ArcticInfo, but due to reorganisation and lack of funds, the Norwegian Coastal Administration was asked to take over the development and operation of the information service.

“As this task was a perfect fit with BarentsWatch’s mandate, we agreed on a collaboration where BarentsWatch would develop the new information service based on data from the Norwegian Coastal Administration.”

Once conditions allow people to meet safely, the Norwegian Coastal Administration plans to host a user conference.
“We want a dialogue on how we can further develop the service to meet the needs of our users. Today, we have basic information that contributes to navigation safety and environmental protection, but there is great potential for creating an even better user experience. In the long term, we envisage integrating information that can support tourism, fisheries, cruise traffic, and public administration.”

Today, users can add important information for authorities responsible for emergency preparedness and search and rescue services in Arctic areas.
In the long term, the next step would be to add digital sailing routes for Svalbard, information about ice routes and icebergs, and whale observations.

“The service already includes Navigational Warnings and Notices to Mariners for Denmark, Greenland, and the Faroe Islands. We are now working to include similar information for Norwegian waters, and we hope to have this in place by the end of 2022. Our vision is a comprehensive and reliable information service where navigators can find important and useful information for safer voyages in the High North.”
