Passage-making: Reunion to South Africa

Weather, weather, weather.

That is all yachties talk and think about before they set off across the ocean. You plan your trip as best you can (wish-list: gentle long-period rollers, no adverse current, maybe a little current in our favour, please?; winds from a consistent direction, consistent strength… maybe 20knots just forward of the beam, please?) and set off on the day most likely to give you a good start…

Hahahaha!!

We left Reunion in the knowledge that this passage around the southern tip of Madagascar was potentially a tough one. The weather and seas deliver absolutely nothing from the wish-lists, as the weather coming up from the Cape consists of a succession of weather front systems, all moving inexorably north and east and over any vessels en route - and when you approach the African coast, the notorious interaction between the SW storm winds and the Agulhas current adds a further dimension.

But our departure was timed for the end of the southern winter and thus the promise of fewer bad weather fronts, so off we set, Rolf and Brian (our nephew) securing the dinghy while underway and Reunion island still in the background…
Wake-up call! See that great flat sea? That was in the lee of the island… we were shocked a few hours later as we churned our way through and over huge swells (4-5m), were pushed by 25-32 knot winds, and had a most uncomfortable start as the waves were all on the beam, lifting us side-on. Then there were some rogues: water over the top of the cockpit roof, water over the stern and pouring forward over the cockpit floor; water over the dinghy as we slewed around and we came the closest ever to sliding down a wave sideways.
From the shelter of the saloon… they end up slamming down on top of the decks
Everything went flying in the galley and saloon (well, come on! We are a catamaran and should experience no more than a tinkling of the ice cubes in the cocktails!) some hatches capitulated and showed leaks when assaulted by solid water at that angle and with that force; a main sail reef line chafed and parted within the first two days, spilling the mainsail and requiring installation of the spare line on a bucking cockpit roof, other smaller bits flew apart and required attention up front and some damage was taken by bodies in the process: the boat demands its daily quota of bloodletting!

Foul weather yachtsman’s gear… and fluffy slippers!
Welcome to ocean crossings (not usually the fluffy slippers!! Just when you need a little TLC on the toes…!).

The following day (day 3) was calm and beautiful, gentle sailing under the screecher sail … and a rest period while we awaited an approaching front. Nonetheless, not all on the wish list was supplied: the current was horrible! 2 knots against us meant that while our speed through water felt great at 6+ knots, we were doing little more than 4 knots over ground in our effort to whittle down those 1500 miles to Richards Bay. This was truly frustrating and in fact we ended up suffering adverse current for almost the whole journey.
What to do on a calm day… getting away from everything in the world!
What to do on a calm day… transfer fuel from jerry cans. Are we having fun yet!?
Of course, the frontal system then hit us – barometer plummeted, winds came in and the log reflects the passage of the system as winds changed from NE to N to NW to SW to S: every wind-shift required attention to the sail plan, whilst we bounced on the sea made lumpy by the changing winds, sometimes having to helm when the autopilot did not cope, squalls passed over us… and the starboard engine died, requiring that Rolf go head-down under the bunk to investigate. The problem was terminal and that engine was off-duty for the remainder of the passage.
Engine oil contaminated with?? discarded into empty jerry cans 
24h Barometer pic tells a tale:
a massive pressure drop shows the low system we went through (12-6h prior); pressure rose as the high system moved in; stable means GOOD!
We have passed through the squall line and leave bad weather behind us: temporarily!

Getting weather downloads with satellite phone: the only place we could connect necessitated making a “table” for the computer.
‘Pile of Cushions’ tables in bucking boats are a challenge - something is going to go!
The high system came over us and again we had a period of calm (day 6) with lovely sailing… and dolphins, the beautiful sight of the setting sun and rising moon simultaneously and finally: the green flash as the sun’s last sliver disappeared. Treat!
Sun sets with moon sliver up high
Day 7 was auspicious for us (!!) as we passed the southern tip of Madagascar: the under-sea Madagascar ridge has huge impact on the waters miles above it, and we suddenly found current in our favour as we crossed this ridge. Hurrah!

But we knew we were getting closer to sea expanses that were more troublesome, with strong currents. Typically, if a strong wind blows over a fast-flowing current in the opposite direction, it produces large steep waves – and the Agulhas current, which flows generally towards the S/SW, is notorious for building up huge seas when a SW wind blows against it.

Our course coincided with the shipping route between the Cape (and SA ports) and the East and we encountered dozens of large ships.

The AIS info on the chartplotter was very helpful, as we could see their course and closest point of approach, and adjust our course.

An intimidating situation: 3 ships approach triangles), closest coming less than a mile away
Sometimes the AIS info entertains:
This ship’s name (Iolcos Confidence) reflects the reason for its confident approach …
with ‘Armed Guards On Board’!
And after Madagascar, there were still two further weather front systems to endure before landfall.
Nevertheless, we finally made it… (adverse current is merely annoying and 6m breaking waves are just babies, really)… and then there was South Africa!
Necessarily sailing into Richards Bay harbour (no SB engine)
Our home flag is now also the courtesy flag of the visited country: first time in 4+ years!
We, and Ketoro, are at home for a bit!
