ARC+ Leg 2: Cape Verde to Grenada

2180nm in two weeks. By the time we got to Grenada we were ready for a break.

The first two or three days were the worst – the genoa furler packed up so we had to drop it into the forecabin. The furler needs to work in case you need to furl the sail in a hurry, for example if a squall hits unexpectedly or man overboard. The genoa is the “power sail” so our speed reduced from 7.5 to 6.5 knots – a shame since we’d had a good start and were sitting around 20th out of 88 at that stage.

The next day we flew the Super Zero, but after an hour or so the tack line cut through the bowsprit so we had to try to take it down. It got horribly caught around the forestay and – long story short – Karen went up the mast and cut the sail away. It was dark by the time she was back on the deck, and her arms and legs were black and blue with bruises. Very brave.

The rest of the trip we sailed using only the mainsail and the jib (staysail), so the passage took two days longer than planned. Laura and Karen prepared some wonderful meals – we ate very well – and under Martin’s guidance, landed a wahoo which we cooked and ate the following evening.

We are now resting and repairing the boat ready for the next part of the journey. We will make our way to St Lucia for Christmas and the start of the World ARC on 7 January.

Sextant Work

I’m brushing up on my sextant skills with the aim of taking (and passing) the Yachtmaster Ocean exam in Las Palmas when we get there. My 500 nm qualifying passage will be Gibraltar to Gran Canaria in October.

The plot today went well, all things considered. There was a clear view of the sun in the morning so I did a standard Sun Sight which plots as a Line of Position. In this case, 112 degrees from my chosen position and 10 seconds (nautical miles) away from it.

The second shot today is known as Sun Meridian Passage. The idea is to take six or eight shots before and after noon and work out the time and angle of the highest point of the sun. At local noon you are on the same meridian as the sun (the sun is directly north or south of you) so the result is a line of latitude, in this case 36 deg 51.1 seconds North. The was a lot of high cloud at 1400 local so I wasn’t very confident of accurate readings.

Finally, in order to fix your position at the time of the second sight, you move (advance) the first Line of Position by the course and distance sailed between the first and second sights, in this case 290 deg and 12 nm. Where the Advanced Line of Position and the noon latitude cross is your position! Magic really.

The final plot looks like this:

The noon sight was taken after we had dropped anchor, so I took a screenshot of my iPad which shows the boat location (red arrowhead) and my calculated position (white circle) about 8 nm apart. Good enough for sailing the oceans!
