Cartagena to La Linea

Hi everyone,

We arrived in La Linea last night after a 60 hour passage from Cartagena.  We had a great 9 day stay there.  The stay was quite social and we enjoyed further exploring the city.  The passage to La Linea was good for the Med with 2/3 of the time sailing.  We had some great sailing, and some challenging sailing too.  Two knots of adverse current while sailing downwind in 25 knots of breeze produced a very unpleasant sea state.  We also came upon an abandoned inflatable boat.

Abandoned Boat

We took the first reasonable weather window from Cartagena after waiting a week for a package which didn't materialise.  The weather window promised at least 36 hours of easterly breeze.  The breeze came in 6 hours after we departed Cartagena.  The track below shows we crossed the shipping lanes twice.  That kept us busy!  Once north of the lanes again we stayed so, gybing north to remain clear of the traffic.

Track

The graphs below show many things but the most interesting is the current we experienced.  The current is well known to flow strongly into the Med through the Gibraltar Straits.  The current flow extends well into the Med.  We had up to 2.5 knots of current against us for the second half of the passage.  This included the period in which we had 25 knots of easterly.  To make things even more interesting we sailed over a sea mount.  Even at 300m deep it seemed to significantly affect the sea state.

The speeds graph below clearly shows the adverse current which added 32nm to the passage, or about 6 hours.

We departed Cartagena in very light winds.  After about 4 hours motoring we spotted what appeared to be a drifting boat.  We altered course to investigate and found it was a new-looking inflatable boat, about 7m in length.  There was no one aboard, no motor, clothes lying in the bilge and one oar.  A set of numbers were painted on the hull.

We called Cartagena Radio and gave them its position and description.  They called us back saying we could proceed on our passage.  We inferred the boat had been intercepted and people (and the engine) taken off by the Spanish coastguard.  They probably painted the numbers.

Farewell Cartagena

A couple of hours later we had a sailing breeze which steadily filled in to become a 20-25 knot easterly. We gradually reefed down until we had a trisail-sized main (2 reefs in our cruising main) and three furls in the yankee.  Initially we were doing 6+ knots over the ground.  Gradually this reduced to 4 knots as we entered the adverse current.  We used the WindPilot for much of the passage and it handled the difficult conditions beautifully.

WindPilot in charge and lovin' it

On our second evening at sea we were joined by a pod of small dolphins.  They stayed with us all night and reappeared the following evening as we approached Gibraltar.  It's always nice to have a friendly escort!

On day 3 the winds gradually died and the engine eventually went back on.  With our diesel supplies running low we transferred our last jerry contents into the main tanks.  We've been running down our fuel level so as to refill cheaply in Gibraltar.

Approaching Gibraltar

We motored quietly into Gibraltar Bay mid-evening.  Twas interesting avoiding everything from large cargo vessels coming to anchor to tiny fishing boats.  We anchored off Alcaidesa Marina for the night.

Dawn anchored off Alcaidesa Marina, La Linea

This morning we motored around to Gibraltar's fuel jetty and took on 180 litres of diesel.  Now we're heading out of the Med our full 240 litres should keep us going for some time.  From the fuel dock we returned to Alcaidesa and entered the marina.

Refuelling @77p/litre

We expect to stay here in La Linea for a week or so.  Hopefully our packages will catch up with us - we're looking forward to having a working RodKicker again!

GoogleEarth KAP Library Update

Hi everyone,

It has been years since we updated our KAP Library of GoogleEarth images.  The library provides satellite images translated into 'charts', primarily for use in OpenCPN and SEAiq.  The library is publicly accessible on Dropbox.

The library and its use are described here.

The full set of blog posts relating to the KAP library is here.

Nearly 4000 new KAP charts

The additions and updates to the library include KAP files in the following countries:

• Africa
• Tunisia
• Caribbean
• Bahamas
• Turks & Caicos
• Europe (limited coverage)
• Ireland
• Italy
• Malta
• Portugal
• Spain
• NorthAtlantic
• Canaries
• Madeiras

The image below shows the new files in Dropbox.  The Bahamas zip file is large at 2.6GB - it includes about 3600 KAP files.

New zip files on Dropbox

The new files were created using VentureFarther's OpenCPN plugin 'vfkaps'.  The plugin makes it easy to create new KAP files.

Your collection of KAP files is welcome in our library.  Get in touch if you can fill some gaps in our coverage!

Monastir to Cartagena

Hi everyone,

Yesterday we arrived in Cartagena, Spain after a 6 day passage from Monastir, Tunisia.  We now have 90 days in the Schengen area before departing across the Atlantic.

Our nearly 3 month stay in Monastir was great.  Being there over the summer it was hot, sometimes very hot.  We enjoyed Monastir itself and also touring Sousse, Mahdia, Carthage and Tozeur in the Sahara.  The Tunisian people are doing it tough but were always friendly.

Final Tunisian Sunset

Our strategy was to take the first reasonable weather window as we approached our 3 month Tunisian visa expiry and our Schengen re-entry date.  Happily one came along a week before the visa expired and a direct passage to Cartagena would have us arriving on our Schengen re-entry date.

The weather window wasn't ideal but it was OK.  We'd have a nice SSE wind to reach north from Monastir to Cap Bon.  The wind would then die and go around to a light W breeze which we'd have to motor through.  We'd motor to get far enough W to ride the western side of a Mistral N wind coming down from France.  We'd sail out of the Mistral into light airs and have to motor until an E wind along the African coast took us home.  There are a set of GRIB weather files below.

Here are the plots...

Departure from Tunisia involves Garde Nationale, Police and Customs authorities.  We first had to arrange a departure time with the Garde Nationale, at least 24 hours in advance.  On the day of departure we then had to visit the police and customs to have our passports stamped.  Customs retained the passports until the Guard National was ready to escort us out,  Then customs came aboard to check our equipment list and look for stowaways immediately before we sailed.  On departure we were escorted by a Guarde Nationale RIB to the 12nm territorial limit.  It took all morning to complete the process, finally departing at noon on Sunday 3rd October.

Departing with escort

We had a great sail north along the Tunisian coast.  Beyond Cap Bon the breeze and fetch made it a rapid but rolly ride.  We zipped across the traffic lanes before gybing west.  In the following PredictWind GRIBs the green dot shows our approximate location at the time.

3 October - nice SSE breeze to start

On Saturday the wind gradually died until at 1445 the engine went on.  It stayed on for 42 hours.  We had to push the engine hard at 2000 rpm to get through an unexpected left-over W swell of 1.5m.  Twasn't much fun.  So glad we spent three sessions in the marina water scrubbing the hull and our Brunton's AutoProp clean.

Eventually the swell subsided and the motoring became easier.  We pushed W to ensure the coming Mistral would be on our beam and not on the nose!  On Monday night a large thunderstorm passed from S to N with enormous bolts of lightning around us.  Happily none touched down close but it's never a relaxing experience!

5 October - light W winds S of Sardinia

Sunset over a silky sea

The Mistral came in as predicted and we had a great beam reach from SW of Sardinia to S of Minorca.  The leading edge of the Mistral had squally conditions and we were caught out by one of them.  A rapid yankee furl and mainsail reef sorted that out, with a free freshwater wash thrown in for both of us.

7 October - riding the W side of the Mistral

Squalls disappearing to leeward

As we reached out of the Mistral the wind gradually faded until eventually we were motoring again.  Along the way an owl flew by and inspected us - what it was doing in the middle of the Med only it can say, it did look a little confused.  We transferred 40 litres of diesel from jerries to the main tanks since the two days of hard motoring had used most of the roughly 120 litres in our tanks.

At sunset on Thursday Nicki saw the green flash.  We've now seen it several times each.  We motored for most of Thursday night, but this time at a much less frantic 1500 rpm across an almost smooth sea.

Tiny hitchhiker

On Friday morning we had a dolphin escort.  It's always a highlight when they come along to play.  The night sky was amazing throughout the passage.  There was a tiny sliver of waning moon on Monday morning and another tiny sliver of new moon on Friday evening.  Otherwise no moon at all.  Jupiter and Saturn were very bright.  We saw a couple of satellites and a number of shooting stars.  The app GoSkyWatch reminded us of the constellations.

Sailing West

Friday afternoon gave us 'champagne sailing' conditions.  It reminded us of trade winds sailing in the South Atlantic.  Nice to know the Med can occasionally deliver perfect sailing.  As they say the Med is often 'motoring between storms', but once in a while there _is_ great sailing.

By Friday night we were closing the North African coast, taking advantage of the predicted breeze there.  When we found ourselves getting into the shipping lanes and close to some offshore platforms we gybed north towards Cartagena.

8 October - riding the wind on the African coast

On Saturday the wind died as we sailed WNW.  Eventually the motor came on again and we donked along at 1500 rpm to Cartagena.

Dodging traffic on approach to Cartagena

Entering Cartagena port

On arrival in Yacht Port Cartagena the marinaro guided us to our pen where we Med Moored (with 'slime lines' not anchor), perhaps for the final time.  We're getting pretty good at the manoeuvring required.

Today (Sunday) we spent the early morning cleaning up the boat.  The headsail sheets were stiff enough with salt for a 2m length to stand upright.  Then we visited the office and found no Covid tests were required for crews of boats under 25m.  We expect to have our passports stamped by Customs tomorrow morning when their office will be open.

We'll be spending a week or more here in Cartagena.  We have several packages en route to us here.  Next stop is likely to be the 250nm to La Linea (close to Gibraltar).  From there it'll be onward to Madeira which will be shorter than this passage!
