Leaving her, again…

My original plan was to bring Sunny Spells back down south to at least Rosslyn Bay (Keppel Bay Marina) before returning to Sydney. Graham Friend had been flagging the Sydney-Southport race on Seaquest (an Adams/Radford 50) for a while, however, and the call to arms came as soon as I was comfortable established in our apartment on Hamilton Island for a five day rest.

Work and other commitments meant I would have to return to Sydney sooner, so on 13 July I single-handed Sunny Spells to Airlie Beach where I had decided to leave her until I could return to sail her back to Sydney.

Graham said he’d never done the passage in less that 3 hours, so I was well pleased with doing it in 2 hours 55 minutes. Running wing-and-wing with a 1.5 knot northerly set on the ebb tide did help! The downwind sail also meant I could comfortably make bacon and eggs on the pushpit barbeque and it turned into a lovely sail. A great way to end this adventure…

Hamilton Island and Whitehaven Beach

After another day of relaxed downwind sailing in the prevailing south-easterly trades, we were escorted into a berth at Hamilton Island Marina early afternoon on 7 July 2008. Our mission was to replenish water, ice and perishables as quickly as possible before sailing to Whitehaven Beach where we intended to anchor for two nights.

Mission accomplished we set sail around 1600 and headed round the northern tip of Hamilton Island and up the Catsey Beach side of Hamilton Island. We were soon close-hauled into the south-easterly, with the crew enjoying the conditions perfectly suited to our boat.

This was the first time the crew had to tack the boat in 10 days of sailing! It was great to sit on the high rail and feel the power in the rig blasting us through the chop, with spray flying everywhere.

With the south-easterly breeze set to persist and strengthen, we elected to anchor off Haslewood Beach, directly opposite Whitehaven Beach. Two boats were already anchored in the best spots, and we found an anchorage in the northern corner.

The bottom shelves very steeply in this anchorage, and it can be hard to find a safe spot to drop the hook while keeping a safe swinging distance from the fringing reef. We anchored just after low tide and, knowing that our water depth would be greater than at anchoring time through the night, I resolved to get up early and review our location. Nonetheless, I spent the first 3 hours watching the bottom on the sounder to make sure we were not swinging too close to the reef. Next morning I was up at dusk, continuing my assessment. I realized soon enough that, with the scope we had paid out the previous night, our swinging circle would soon be bringing us closer to the reef than I liked. The windlass was used to slowly bring us closer to the anchor and away from the reef. One of the boats left early and we soon pulled up anchor and relocated south. Shortly after, the other boat, located in the best spot, also left, and we dropped the hook just atop the shelf in about 7 meters (low tide) and put out 40 meters of rode. This left us swinging comfortably clear of the reef but still provided almost 4:1 scope at high tide.

A little later, almost at high tide, we were treated to the sight of a chartered Beneteau 32 steaming into the anchorage at 5 knots, straight across the fringing reef, to drop anchor inside the reef, about 20 meters from the beach… A potential disaster at low tide was averted when they soon decided on a more prudent course of action (possibly after radio discussion with the charter company) and relocated across the passage to Whitehaven Beach, where about three dozen charter boats were safely anchored.

The day was squally with lots of rain and gusts up to 28 knots. We were appalled when monitoring the weather broadcasts from the charter companies to hear forecasts for 10 to 15 knot winds…

Towards the evening we all had to get out, and I went for a lovely snorkel on the reef. My one regret is that we didn’t really have great diving weather. While it was fun snorkelling, the lack of direct sunlight meant everything was pretty grey and low-contrast, so there was no point donning the Scuba gear. Oh well, there is always the return passage!

On Wednesday morning the crew went for a quick snorkel while I got Sunny Spells ready. We pulled up the anchor at around 0800 and the crew soon had the full main up as we motor-sailed out the passage. A boat coming the other way (looked like a 40ft+ Beneteau) was running downwind with three reefs in the main and just as I was about to make a remark on the weatherliness of modern boats, I checked myself and called for two reefs in the main. As we came out of the passage into open waters the full strength of the south-easter hit us, and we were soon broad-reaching towards Hamilton Island in 25 to 30 knots of breeze with the spray flying. This was the perfect way to end our ten day passage. The crew were working together like they’ve been doing it for years and I realized I was going to be very sad to see them go…

VHF Interference from Autopilot

I noticed in the web log stats that someone had searched for “VHF interference tiller pilot”. This reminded me that I had a problem which occurred soon after the new electrical panel was wired: whenever I turned on the autopilot, there was a constant buzzing interference audible on all VHF channels.

The source was as I had expected: an earthing problem. I used the Seatalk cable to connect to a NMEA multiplexer and the NMEA input to connect to my chartplotter, both of which were earthed, but the primary power input negative (earth) was not connected (d’oh!). The resulting high currents on the signal earths for Seatalk and NMEA caused RFI which was picked up by the VHF antenna.

Many years ago I built an audio (hi-fi) amplifier which had earth loops because of multiple return paths to earth – the AC mains hum was unbearable! Fortunately I remembered that lesson.

The best strategy is always to run all earths (and power supply grounds) to a single earthing point such as the main negative terminal on your electrical distribution panel.

Of cooking and fires at sea…

While at anchor at Whitehaven Beach in the Whitsundays, we had the misfortune of our alcohol stove catching fire, nearly burning us down to the waterline. If we weren’t actually watching the stove at the time, it could have easily turned out a nightmare. Here’s what happened…

Sunny Spells is fitted with a MaxiMarine alcohol stove (two burner with grill) of fairly recent vintage, installed on gimbals. I’ve always been uncomfortable with the procedure for lighting the stove, which feels a bit like starting a barely controlled fire. A little methylated spirit (metho) is dripped into a tray around the burner and lit. This liquid metho burns and heats up the burner itself. Once the burner is hot enough to vaporize the metho, the alcohol flow is turned on again and the metho vaporizes and burns cleanly, a bit like a propane stove.

Our MaxiMarine alcohol stove

Getting just enough metho into the tray initially is a bit tricky, and you either don’t have enough or the alcohol burns quite vigorously while you watch it (very nervously).

On this occasion, we had all three burners going, including the grill. For some reason which I still can’t determine, the metho started pouring out of one of the burners (I suspect the grill), flooding the bottom of the stove and then running onto the cabin sole. When this caught alight, it was seconds before we had a roaring fire!

Fortunately, the fire blanket was close to hand and this was quickly thrown over the fire and I then closed all the control knobs on the stove. Unfortunately, the fire was still burning and getting out of control. I then grabbed the fire extinguisher, took a couple of seconds to remove the safety pin and work out which way to point it, and then discharged it into the fire under the fire blanket… The fire went out instantaneously – to our combined relief! The fire blanket had helped to slow down the fire, but in future I’ll be grabbing the fire extinguisher at the same time!

To say we were all a bit shaken, if not stirred, is an understatement. In the seconds before using the extinguisher I was about to urge everyone to abandon ship, it was that close…

The inside of the boat was covered in powder, a substance we found pretty difficult to clean up. We took the stove outside, cleaned it and then started the two burners (not the grill) on deck, where it operated flawlessly. The stove was reinstalled and used for the rest of the trip without any incident.

The problem now, of course, is that I don’t trust the devil…

I’ve learned a lot from the experience though:

  • In my initial safety briefing I concentrated on sea safety (MOB procedures, harnesses etc..) but we didn’t cover the fire-extinguishers, which I left for a later briefing which never happened. When I briefed the crew on the use of the stove I eplained the use of the fire-blanket, but the most experienced crew member, who had used an alcohol stove before, was on the helm at the time. Of course, she was the one doing the cooking when the stove decided to go up in flames!

    Lesson 1: make sure the crew is briefed on fire fighting and that they all get the opportunity to handle the fire blanket and fire extinguishers.

  • I was intrigued by my subconscious resistance to firing a $20 fire extinguisher while the boat was going up in flames…

    Lesson 2: Be mentally prepared to use the fire extinguisher.

  • I fumbled with the fire extinguisher: first I couldn’t get it out of its bracket, then I had trouble getting the safety pin out and, finally, I had to force myself to loook at it carefully to find the trigger and make sure the nozzle was pointing the right way (while having a very urgent, flaming distraction in front of me).

    Lesson3: Familiarize yourself and the crew with the fire extinguishers so you can use them with your eyes shut.

It does raise the old question again about cooking on board: propane vs alcohol? I don’t know the answer to this one. I do feel a bit biased against the alcohol stove now though, but is an explosion better than a fire?
