Tips for a safe passage

 

โ€ข Take the time to prepare your boat well. Work with your safety inspector or use the C&OC Safety Checklist Linked Below.
โ€ข
Plan your passage in advance, donโ€™t try and do it on the fly. Have a back up route and destination in case of emergency.

โ€ข
Make regular radio skeds, email reports or use PredictWind tracking to advise a shore contact of your plans, destination, position and ETA.

โ€ข
Prepare your crew. Practice sail work, explain the boatโ€™s systems and talk about safety procedures and where to find everything.

โ€ข
Check if your crew is on any medication, if they get seasick they wont be able to hold down their medication

โ€ข
If any of your crew are the least susceptible to sea sickness, have them start taking something for it, BEFORE you set sail.
โ€ข Have a grab bag handy at the foot of the companionway in case of emergency.
โ€ข Set up a watch system. Whether itโ€™s two, three or more crew, set up a watch system so everyone knows what they are expected to do. Always keep a good lookout.
โ€ข Set up a schedule for chores and make sure everyone has their fair share. Leaving all the cooking and cleaning up to the misses is one sure way to have a grumpy partner.
โ€ข Pre-cook some passage meals BEFORE you leave, one pot meals are best and where possible have them pre-frozen ashore.
โ€ข Make a box full of sandwiches to have available for the crew whenever they are hungry.
โ€ข Have lots of high energy snacks on hand.
โ€ข A well fed and rested crew is a happy crew.
โ€ข Reef down early, itโ€™s easier and safer. Itโ€™s a good idea to reef down before dusk if the forecast is even a bit uncertain.
โ€ข Have a daily check around the boat for chafe and things that can come undone, like shackles etc.
โ€ข Most important of all, keep the skipper happy. Remember he or she takes ALL the responsibility and a tired skipper is more likely to make mistakes.
โ€ข To the skipper, remember you are the boss but also remember what happened to Captain Bligh

Sailing in Aruba: A Nautical Adventure in the Caribbean

Aruba is a small 20nm island located in the southern Caribbean just north of the Venezuelan coast.
White sand beachesย  areย  one of the island’s primary draws. Over 300 cruise ships visit Aruba every year.
It is known for its turquoise waters, constant and often elevated trade winds.

The Allure of Aruba

Arubaโ€™s location outside the hurricane belt means that it enjoys stable weather patterns throughout the year, with minimal risk of severe storms.

Essential Tips for Sailing in Aruba

1. Navigation and Charts: While Arubaโ€™s waters are generally safe for sailing, itโ€™s crucial to have up-to-date nautical charts and GPS navigation tools – there are reefs and shoals to watch out for.

2. Weather and Wind Conditions: The trade winds blow consistently from the east, ranging from 15 to 25 knots. These winds provide excellent consistent conditions, but sailors should be prepared for gusty periods, particularly during the afternoons.

3. Customs and Regulations: Aruba is a pass through destination for international sailors, but itโ€™s essential to clear customs and immigration upon arrival. Ensure you have all necessary documents, including passports, vessel registration, and proof of insurance.

4. Safety and Preparedness: Always have a well-stocked first-aid kit, life jackets, and emergency communication devices on board. Familiarize yourself with local emergency contacts and procedures.

5. Respecting the Environment: Arubaโ€™s marine ecosystem is delicate and requires protection. Follow all guidelines for waste disposal, anchoring, and reef preservation. Avoid anchoring on coral reefs and be mindful of marine life.

Activities and Attractions

1. Snorkeling and Diving: Arubaโ€™s clear waters are goodย  snorkeling and diving. Popular spots include the Antilla shipwreck, Arashi Reef, and the coral gardens near Mangel Halto.

2. Beach Hopping: Aruba offers plenty of opportunities for beach hopping.

3. Cultural Experiences: Explore the vibrant culture of Aruba by visiting local markets, historical sites, and museums. The Bon Bini Festival in Oranjestad plus lot’s ofย  traditional music, dance, and cuisine.

4. Dining and Nightlife: Aruba boasts a diverse food scene, with restaurants offering everything from local Caribbean dishes to international cuisine.

5. Water Sports: Auba is a hot spot for various water sports, including windsurfing, kiteboarding, The consistent winds and calm waters make it an ideal location for these activities.

Planning Your Sailing Trip

1. Best Time to Visit: While Aruba is a year-round destination, the peak sailing season is from December to April, when the weather is slightly cooler and the winds are at their best.

2.ย  Provisioning and Supplies: Ensure you have all necessary provisions before setting sail. Major supermarkets and local markets in Oranjestad and surrounding areas provide a wide range of food, drinks, and other essentials.ย  As it is an Island economy the cost of living in Aruba is, on average, 16.2% higher than in United States.

ARUBA HISTORIC HURRICANE TRACKS

PILOT CHARTS

Aruba Pilot Charts provide historic points and aggregated information ofย  wind flows, air and ocean temperatures, wave heights, rain, barometric weight, and climate conditions at various seasons. This data was acquired from oceanographic and meteorologic perceptions over hundreds of years starting in the late eighteenth century. These diagrams are planned to help mariners choose routes around and approaching Cuba with respect to the normal climate and sea conditions using prevailing seasonal wind information.

PORTS OF ENTRY

Clearance Procedure

Aruba has different procedure for clearing in and out as other islands in the Caribbean: At arrival, all vessels are required to go to an official port of entry first! The vessel will have to be cleared both by Immigration and by Customs.

For your convenience you can print and fill in the necessary clearance forms (three copies for Immigration, two copies for Customs).

Skippers and crew can initially stay 30 days. For yacht crew this can be extended to two times 90 days. 180 days per year maximum. Yachts can stay on the island up to 180 days. After this they will need to be imported. Exception: Yachts in dry storage atย  Varadero Aruba. While in storage the 180-day count is stopped.

For the latest information and travel advisory update from the Aruba Tourism Authority regarding the measuresย  visit Aruba.com

Immigration

First clear with immigration then go to Customs.

When clearing in there is one point to keep in mind: We suggest that you ask immigration for a longer period then you intend to stay. Should your plans change you will not have to spend time to get an extension.

Visa requirements: None for citizens of the USA, Canada or the EC. Other nationalitiesย  download entry requirements.
Although Aruba is part of the Netherlands, visa for the Netherlands Antilles are not valid for Aruba.

STRAIT OF GIBRALTAR

STRAIGHT OF GIBRALTAR

STRAIGHT OF GIBRALTAR
Over 100,000 ships transit through Gibraltar every year

Density of seawater in the Strait of Gibraltar One of the unique features of the Strait of Gibraltar is the inflow and outflow of the Medย  which consists of layers of water with different salinity (salinity). Atlantic water is less saline and less concentrated than Mediterranean water, and flows eastward into the Mediterranean through straits as a surface layer, flowing at a speed of 2 to 3 knots at a depth of about 125 m. In contrast, heavier, cooler, and saltier water flows westward into the Atlantic Ocean. Depending on the phase of the tide, the currents flow eastward faster or slower.

 

 

Tides in the Strait of Gibraltar โ€“ย 
A very distinctive feature of the Strait of Gibraltar is the continuous evaporation of water. Vertical water height in the Mediterranean Sea decreases by almost 1 meter every year. About 6.5+ million years ago, the general shape of the Mediterranean base was similar to what it is today. The movement of the plates cut off the flow of water from ocean to ocean, completely evaporating the area. But about 5+ million years ago, the plates moved again and the straits opened, allowing large amounts of water to flow out of the ocean and refill the Mediterranean basin. This evaporation continues today, and it is estimated that if the strait were to close at current high sea levels, the basin would evaporate again. Backwash and Internal Waves Adding another challenging piece to the tidal puzzle that shapes the Strait of Gibraltar near the African continent are the often narrow two-knot backwashes that interact with the Caminal Stile (the shallowest part of the strait) and cause internally generated waves. As stated by NASA; "The waves are generated when daily tidal pulses flow through the shallow Caminal Stile near Gibraltar. They flow eastward and break up the coastal topography. They can be traced up to 90 nm, and in some cases produce interference patterns due to refracted waves

Internal waves are vertical movements between two layers and can have displacements of over 100 m with wavelengths of 1-3 nm. They are so noticeable as surface wave patterns that sunlight is carefully scattered by the water surface


Alboran Gyre

As the upper-level flow pours into the Mediterranean, the Coriolis force (an effect of the earth's rotation) causes it to form a large clockwise eddy (gyre) off the North African coast called the Alboran Gyre. A smaller weak anti-clockwise eddy forms to the North. Countercurrents (westward direcction) can be seen close inshore along both shores, particularly near headlands that project into the current.

The western end of the Mediterranean, akaย  Alboran Sea, is the habitat for aย  largest population of dolphins in the western Mediterranean

A layer of outward-flowing dense water stays deep after exiting the Mediterranean and forms a ribbon extending along the Spanish and Portuguese coasts at about 1000m depth.

Transiting the Straits of Gibraltar

Navigating the Straits of Gibraltar requires careful planning, considering wind, tides, currents, and potential orca encounters. Here are the key points for a successful passage:

Timing and Conditions

  • Wind: Prevailing winds are the Levante (east) in summer and Poniente (west) in winter. Avoid strong winds; a light or nearly windless forecast is ideal.
  • Tides and Currents: Complex patterns; use a Tidal Stream Atlas for guidance.
  • Forecasts: Use ECMWF models and monitor Tarifa Radio for updates.
  • Shipping Traffic: Stay clear of busy lanes and cross perpendicularly if necessary.

Beyond devastated. Thatโ€™s how we feel right now. Itโ€™s been a while since Iโ€™ve really documented our nomadic lifestyle. We have sailed from California, USA through Mexico, Costa Rica, the Pacific side of Panama, through the Panama Canal, the Caribbean side of Panama, through Colombiaโ€™s โ€œpirate alleyโ€, and two thirds the way to Aruba, actually into the waters of the Netherland Antilles. We met some of the most amazing adventurous people along the way who will forever be in our hearts. Some of them we met in California and others in Mexico. Some have split up but then we meet back up and call it โ€œbungee-boatingโ€. Some we will never see again. But yesterday morning we split up unexpectedly, heart wrenchingly. After motor sailing for 2 days and 2 nights in benign sea conditions, the weather took a drastic turn. Suddenly while on night watch, 25 knots of steady wind came out of the Atlantic and the seas starting pounding. By daylight we were feeling drained from a lack of sleep and our buddy boats had begun drifting away. We were still fine, all communicating on VHF radio, and eagerly waiting to just get through it for another 40-50 miles so that we could wake up to sunny Aruba and eat an anticipated Dutch breakfast. (You shouldโ€™ve seen how excited Rolf grew a few nights ago when it dawned on him that we were going to sail to a country where people spoke his language and he could eat Dutch food again.) But then suddenly a new tie down strap for our dinghy snapped and blew away. Shit! Because we were bashing there was a lot of force and our dinghy davits were compromised, now damaged and weakened. We had another new strap and were able to secure the dinghy. Good. But, our solar arch is also partially sitting on top of the davits and now the dinghy and solar panels are at risk of just breaking off and going kerplunck into the angry ocean. If that werenโ€™t enough, we had a 2 knot current that we were fighting against while feeling like we were riding a bucking bull. This slowed us down to a whopping 1 knot of โ€œspeedโ€. We were crawling and waves were crashing over our bows every now and then. Making life go from worse to miserable, our autopilot shutoff because it couldnโ€™t keep up with the bashing. Conditions matter. And yesterday morning was a perfect example where with rough seas, strong current, and high wind (all on the nose) was a trifecta for poor motor performance and loss of the autopilot. So we had to make one of the toughest decisions ever - either steer by hand for 2 days and crawl to Aruba or turn back to Colombia. The main considerations were the stability of our dinghy davit system, our own safety & fatigue, and the comfort of our 14 year old dog, who was clearly suffering too. We bashed for an hour debating back & forth whether we could make it safely to Aruba or turn back. The problem was that the weather forecast now indicated the wind and sea state could persist for another couple of days. So with immense sadness we turned around. ๐Ÿ˜ญ๐Ÿ˜ญ๐Ÿ˜ญ Now weโ€™re alone, sailing back down the Colombian coast to Santa Marta, maybe even back to Cartagena. Next up, we have to still work our day jobs, which can be stressful and demanding at times while we figure out how to reinforce our dinghy davits and consider replacing our props. Really, I wish we could buy a bigger and more powerful boat with tons of horsepower for the 5-10% of the time we really need to motor hard from one amazing destination to another. But for now, Iโ€™m back to the night watch cruising solo. At least weโ€™re comfortable with the wind and swells behind us and our sails are up.
