Cartagena is a great city and we wish we could have wintered over there - the western med is great and full of places to sail and see. We spent 2 years and did not touch
parts of it and hope to make it on our way out.
NOW - you said something very disturbing - you did not check the weather - I am astonished that a kiwi sailor did not look at the weather. Hopefully you learned a valuable lesson. Not sure what you are using for weather but we have
ssb and download gribs but only if we do not have
internet coverage. We get a dongle for each country we visited and it paid huge dividends. By the way we use windfinder and a uk model and a long range
forecast model from noaa and just learned about windyty and playing with it now as it gives us a great view of stuff a long way away as we do our planning.
Have a great time planning as there is a lot to see and do.
