A Plastic Free Boat

I find myself thinking often about plastics and our impact, in general, on the world out here. The beaches of paradise are littered with plastics. Even remote Suwarrow would yield a few garbage bags full from the small beaches on the main island.

So is it possible to cruise without using plastics? It would certainly reduce our dependence on fossil fuels to do so, but without a huge effort, I think it is not feasible. Too many things we take for granted are made from plastic.

Starting with the boat, we would have to build one from some other material other than fiberglass, which is plastic resin reinforced by glass fibers. Our running rigging would have to be replaced with wood or metal blocks and lines made from natural materials such as hemp or sisal. We would forego electricity on board, because wires and connectors use plastic for insulation and almost all electrical devices are made at least in part from plastic, valuable for its insulating qualities. Reverting to cloth covered wire and wooden/metal appliances might be possible, but the results would be unlikely to hold up in a wet, salty environment. Without electricity, we lose our depth sounder, GPS, and lighting. The latter would need to be done entirely with kerosene and would require lanterns for the running lights (two or three), anchor light, and interior lights. We would have no engine, since the pipes that feed water and the many of gaskets that seal it are made of plastics. Plumbing would also have to be re-done with metal pipes only, sealed with lead or oakum joints. We would have to look long and hard to find a metal compass to navigate by and an all metal sextant for off-shore work. Our chronometer would also need to be all-metal and glass - hand wound. I suspect a 'simple' non-plastic boat would cost more to build and be a pain to maintain.

Re-provisioning would be possible, but difficult, without plastic, since most processed 'foods' are packaged in plastic. We would bring cloth bags to the local market and have to be very choosy as to what we bought in the grocery store. Perhaps this is where we can have the most impact - by buying fewer plastic containers, especially out here in places like Tonga, where most plastic is simply thrown on the ground, burned, or dumped in the ocean.

Day 4 - purring engine

Yesterday saw us making quite good progress from the early morning on. We had sailed under the edge of a bank of low grey clouds, hoping to take advantage of some winds after a too calm night. This proved to be a good move, for while our friends 20 miles away were motoring, we sailed all day in breezes up to 10 knots. The seas were down and the wind only a little behind the beam. Eventually as the wind died down, we unfurled all sail and were still making 4 knots when we noticed around sunset that we would soon sail out from the edge of the front and into clear skies.

As I guessed, this meant the end of our wind, and after sailing southeast (90 degrees from our desired course) for a few hours, we finally lost any semblance of forward movement. There was still enough swell to make taking down all sails and waiting it out an unpleasant prospect, so we started our diesel for the first time on this passage. She has been purring away at 1300 rpm, pushing us at 3.5 to 4 knots for several hours now, while we doze below with ear plugs in to drown out the unaccustomed din.

We had our first movie on passage - a late afternoon matinee, watched while we still had a reliable breeze. The feature presentation was "The Best Years of Our Lives" - a nearly 3 hour long movie about servicemen returning to their US hometown after World War II. This An excellent film with thoughtful dialogue and very good acting. It deals with the difficulties soldiers, sailors, and civilians experienced adjusting to a changed life after the prolonged upheaval of war. Many of the truths the movie explores are still relevant today. I guess this is what makes a classic.

We saw one boat last night, which motored past us maybe 4 miles off as we sailed sluggishly to the southeast. Also, our friends on 'Melody' suffered a broken paddle shaft on their Aries windvane self-steering gear. We checked our Monitor windvane parts, but determined that our shaft replacement piece would not fit their gear, despite the American Monitor being a copy of the British Aries. Holge on Melody believes he can sleeve the shaft with a slightly modified winch handle, but will need to stop in Minerva to make the repair.

We have been sailing through fields of pumice, the detritus of an underwater volcanic explosion that occurred nearby. Apparently the pumice reaches all the way down to New Zealand,. So far, it has not affected our water cooled engine.

At 7:45 we were located at 23 11 S 177 56 W - Te sails are up in 1-2 knots of SW wind and were making 1-2 knots in relatively smooth seas.

Chasing squalls!

It is Day 3 and we are wishing for a little bit of that wind from Day 1. Yesterday was beautiful with the 10-15 ESE, blue skies and sunshine, but just after supper we were shaking the second reef out of the mainsail as wind speed dropped to less than 10 Knots. After midnight, we were being thrown around by 2m swells from south and east and the sails were slatting in less than 5 knots from the east. Neither the windvane nor the tiller pilot were able to hold the SW course to Minerva Reef, so we turned south and then southeast to keep going. Other boats close to us reported that they had either taken the sails down and or switched on the motor at around the same time.

This morning we were excited to see a line of squalls south of us. Wow!Wind! We deliberately changed our course to get some of that wind. And maybe we could get a boat wash at the same time! As we approached the biggest and blackest patch we put a second reef in the main. "Hurrah, we are up to 6 knots plus again!", we sang over the radio net. That elation was short lived. Another hour later we were shaking out the reef again. These squalls seem to be light and static, hardly moving at all, but we are still chasing them to keep moving, even if it is in the wrong direction and at only 4 Knots.

According to the weather sources we will be in zero to light winds for the next two days. This means we may stop at Minerva Reef for a day if we get there in a day or two. But nothing is for certain. At times like this I wish I were on a fast boat like Segue, a large Canadian catamaran which set off later than us from Vava'u but anticipate being in Opua by Friday. They made 224 miles in 24 hours on Day 1!

Our position this morning at 0745 was 21 59 S 176 51 W. We ran 131 miles in 24 hours but probably only 100 in the right direction.

Position update Day 2

It's Remembrance Day at home - a day later out here and we are enjoying much more peaceful conditions than yesterday - winds 10-15 ESE and seas down below 2 meters. Still bumpy but much less water on deck. Position at 7:45 was S 20 17 W 175 47 - we made 148 nautical miles in the first 24 hours from our anchorage in Vava'u - an average of over 6 knots.

In retrospect, we should have sailed a bit further west to make things a bit less violent on board. Making tea in 3 meter seas and 25 knots is a potentially painful experience. Today we were able to cook and eat porridge with only a slight boil-over.

First night en route to NZ

We departed about 15 hours ago from Tonga bound for New Zealand amidst a fleet of fellow cruisers. The seas were still rough - left over from the low that passed a few days ago to the south and a new chop produced by 20+ knot winds. We have been close reaching with water washing over the decks and coach roof and finding its way inside through hatches and portlights that no longer seal entirely when submerged in green water.

There has been much chatter on the VHF and sharing of weather data on SSB. A few of the boats have signed up for custom weather routing and are generously sharing this with the fleet. I wrote a small program to covert some of these data to a route that can be displayed on OpenCPN - my small contribution to all this.

Position at 11:15 PM local time 19 38 S 175 09 W - - somewhere off two volcanic islands in the Ha'apai group of Tonga.

Will try to do daily updates. The passage should take less than two weeks and we may break it up with a stop at Minerva reef.

Rotis and Routes

On this eve of our departure to New Zealand, we ran through our 14 point "to do" list in a very tranquil anchorage. Most importantly we inspected the standing and running rigging, fixed the leaking portlight which dripped saltwater over the settee during our last passage and re-enforced the lines which hold the solar panels and wind-vane steering in place.

We also held a pre-passage meeting yesterday with other yachtie friends who are leaving from Vava'u to discuss the weather and route strategy. Everyone is keen to leave as soon as possible and while a few were ready to depart today, most of us had to re-provision and will depart tomorrow or Monday. The forecast looks good with moderate winds and seas for up to one week. Of course, the wind is a fickle friend and depending on the dance between the highs and lows of barometric pressure, it may become overly enthusiastic or desert us altogether. The main thing is to keep abreast of the meteorological reports spanning more than a thousand miles. Over the next two weeks, we shall be staying in touch with David from Gulf Harbour Radio, NZ, and downloading grib files (computer generated wind and sea states) and some friends are receiving personal weather routing.

I had the enviable task of galley duty, preparing some simple meals to eat during the next couple of days while the swells may not be conducive to culinary creations. As a result we have a large container of hummous, fourteen plain rotis, a saucepan of lentil, chaco and carrot stew, and some cut mangoes, papaya and pineapple for dessert. There was not enough to bake the almond cookies, so hopefully there will be quiet days at sea to do so.

On a positive note, the people on Windigo, the boat we reported as being rolled a few days ago during the deep low, have been rescued and are on their way to New Zealand. The boat was abandoned and is apparently still floating, so we will be on the look out for it on our passage through that area.

Anyway - we are ready! So wish us good luck and we will be on our way after breakfast tomorrow. We will try to post a daily position report and check into the Pacific Drifters Net on SSB 8131 USB at 0715 and 1730 local NZ time.

Update to post regarding Windigo

We received more details on the rescue effort regarding Windigo. The vessel was not abandoned as had been reported this morning. She was rolled and suffered some damage and is taking on water through leaking hatches. The crew is still on board and two large vessels were en route to the scene as of noon today.

First cyclone of the season?

We have been watching the barometer rise and the winds rotate into the west as a deep low has passed south of us. While we have not heard it called a cyclone yet, I think it could be classified as one. Some boats on its less violent northern side reported gusts of 74 knots. Our friends Bruce and Marcelle on 'Adventure Bound' reported 10 meter seas and winds in excess of 55 knots yesterday and this morning. They sounded very unhappy to be where they were, which today is the area with the highest forecast seas (at 7 meters) south of the center of the depression. Yesterday we heard they were hove to, but today they are making their way slowly (at 2 knots) north in response to a request from New Zealand emergency response.

As far as we can understand from sketchy reports, a 39 foot Beneteau named 'Windigo' was rolled over in heavy seas 30 nautical miles to the north of 'Adventure Bound'. They set off their EPIRB and took to the life raft. A New Zealand Orion rescue plane has been standing by and 'Adventure Bound' has been asked to head towards the life raft and take the passengers on board. Chris tells me that for a boat as large as Windigo to roll completely over requires a breaking sea of about 8 feet - that would be on top of the non-breaking part of the swell. I do not know for sure if the vessel was completely rolled. Perhaps she may have suffered a knock down that filled her through open hatches.

The rest of the fleet en route to New Zealand are all experiencing rough weather (winds 30-40 knots) and high seas from 3-5 meters. On the Pacific Drifters Net this morning several sailboats reported less severe damage, for example a broken boom vang and leaky portlights. Believe me when I say that I am not looking forward to this passage at all! I volunteered to winch Chris up the mast to inspect the rigging before we set off.

Closer to here, about 130 miles south of Tongatapu, an unregistered EPIRB was set off. Because it was not registered, we have no details of which vessel set it off. Also, just south of us in the Vava'u Group there is a sailing boat on a reef. The Tongan police are trying to rescue the vessel, but its crew is not in danger.

Finally, our friends on 'Kindred Spirit' had their mooring in Neiafu part company last night around dusk but were able to react quickly enough to save their boat. I am glad we did not take them up on their kind offer to raft up with them! We are anchored off a somewhat surfy beach with about a 2 mile fetch to the west, from which the wind is now blowing. I had some concerns about our anchor chain being wrapped around coral and spent an uneasy night wondering if it would be sawn cut but Chris reassured me that there are small rocks not coral close to the anchor. Being a worrier, I still kept a close eye on our GPS position, ready to hop out to start the engine if the anchor drag alarm sounded.

The front is moving quickly away now and we anticipate better conditions later this evening as the wind swings behind a nearby island and the fetch subsides.

Our thoughts and prayers are with the people out on the open ocean today, in particular the folks off 'Windigo' and Bruce and Marcelle on 'Adventure Bound'.

Highs and Lows

At least it is not the first cyclone of the season, but there is a deepening low passing through Tonga today that has had the cruising community worried for days. With our SSB long range radio, we have been able to download weather forecasts and listen to radio nets discussing what is coming. This is so different from the trip I made a few years ago to take our smaller boat back to Canada when we had a poorly functioning radio receiver and less knowledge about receiving weather information in this way. At that time, I could only look at the barometer and the sky and try to work things out from that and a few rudimentary rules of thumb.

This low will pass south of us with the winds rotating anti-clockwise from east to west as it passes. We sailed about 90 miles north yesterday, returning to Vava'u from the Ha'apai Group. Here the winds should be lighter and the protection is much better, especially in westerly winds. It was rough sailing once we were clear of the low islands of Ha'apai. With large and closely spaced swells just ahead of the beam, the decks were awash with water for many hours. We noticed two leaks on the starboard side - one we knew of already and another around a portlight frame. Winds were about 20 knots from the east and we averaged a respectable but bouncy 6 knots close reaching under 2-reefed main and partially furled jib.

Our arrival in Vava'u well after dark was made possible by the fact we had been here before, and had sailed through most of the channels we followed into this maze of islands. Also, we had newly surveyed charts, with land masses and reefs in roughly the right places. Still, we ran the charting program and radar and kept a close eye on the depth sounder as we made our way through more than 10 miles of passes and channels. We anchored around 11pm just off Nuku Island, the only boat in the area. Most other boats that returned to Vava'u are in Neiafu where they are tied securely to moorings, but there were none left by the time we neared the islands.

This morning we re-anchored Ladybug in a better position for the winds expected and in deeper water off the beach. I snorkeled around carrying a leadline with float attached to mark the spot. The anchor looks well set with a large fishing float holding the chain above some coral bommies nearby.

There is a great deal of camaraderie in the cruising community and we received helpful emails from our friends Don and Deb on 'Buena Vista' as well as assistance via VHF as we approached from Brad on 'Kindred Spirit' and Mike on 'Picara'. When you are beating your way through rough weather towards a safe haven, it is a great comfort to hear a friendly voice!

Grahame Shannon's Walker Bay

Grahame Shannon designed both Ladybug II and was one of the designers of the Walker Bay dinghy. Walker Bays are manufactured in the thousands by a company out of Washington state in the US. Mr. Shannon's website states that the Walker Bay is the most popular dinghy in the world. There is an 8' 3" model (the Walker Bay 8) and a 9' 9" model (the Walker Bay 10). We bought our Walker Bay 8 in Mexico, second-hand and in well-used condition, but with a nice sailing rig and upgraded oarlocks. We named her 'Little Annie' as a tribute to the lovely lady who runs Yoga classes in La Paz and who sold her to us.

The Walker Bay 8 is a good fit for Ladybug. At just over 8 feet, she fits nicely on deck with her bow tucked between the windlass and the starboard rail and her stern resting on the coach roof just forward of the two large hatches. She covers the V-berth hatch, but this can still be opened for ventilation in very light seas. 'Little Annie' is the same cream colour as our hull.

The Walker Bay 8 rows very well with one person, but has been criticized for her ability to row with two. This stems, I believe, from a problem in balancing her out with a passenger sitting in the obvious place - the transom. Unless the passenger is a child, the transom submerges and the extra drag from this makes the dinghy very sluggish under oars. There are three solutions to this on our slightly modified boat. Rani and I share the center thwart, back to back, with me rowing facing aft. This works well if the forward passenger is lighter than the rower - otherwise the boat is a bit down by the bow and may be more difficult to keep tracking straight. The transom does not dip in either case.

The second solution is for the passenger to sit on the forward or center thwart, depending on how heavy they are relative to the rower and for the rower to row facing forward. Some people find this position awkward because you must push instead of pull, but it is good exercise and allows you to see where you are going. It does not work well in higher winds because you cannot put your back into it - maybe I am just a weakling!

Finally, you can install a second set of oarlock sockets further forward, between the main thwart and mast partner, as we have on 'Little Annie'. This allows the rower to sit on the mast partner and the passenger on the aft thwart. The rower must row cross oared as the beam is much narrower this far forward.

A word on oars. 'Little Annie' came 5 foot long aluminum dinghy oars, which are much too short to work well on a boat with more than 4 foot of beam. The standard (I believe, 6 foot) oars are ok, but adding an extra foot gives you a lot more power. We added closet poles to our aluminum oars, which fit perfectly inside the aluminum handles and give us 6'6" oars.

Some negatives - 'Little Annie' is much less stable than an inflatable. Friends who are used to their rubber dinghy admired our walker Bay, but found it too tippy to be practical. Inflatables are also better for carrying dive gear and getting back into from the water. That being said, we snorkel from the Walker Bay and get in and out no problem, but I weigh only 150 lbs and Rani about 100. The plastic that the dinghy is made from is soft and flexes a lot when sailing into a breeze. She also flexes a lot when used with even a small outboard motor (so I am told). Finally, she is tricky to repair. Plastic welding - at least the way I do it - does not yield a strong repair. I have had to back up my welding with riveted patches of aluminum sheet.

Some pluses - rows well with one or two people, so long as you keep her transom out of the water. She glides along far better than our previous hard dinghy. She carries enough load for two (lightish) people out cruising. Despite flexing a little too much for comfort, she is a good little sailor with our 40 sq foot Bermudan rig. This allows us to travel far greater distances than by oars alone - no motor required. I like the simplicity of this approach and it is also great recreation in a sheltered bay with a nice breeze blowing. Her soft polypropylene does not mar our topsides or decks and hence require no deck chocks or padding of the gunwales.

Thank you to Mister Shannon for an excellent small dinghy.
