Underwater Mechanic

Matt wears many hats on the boat.  Engineer, electrician, mechanic, refrigeration, fix it man, chef, etc…Today, he wears his underwater mechanic hat. I will show you how he changes the zincs on our starboard prop while underwater. 

Conditions

We have to have pretty good conditions in order to do this project underwater.  First, little to no wind.  We don’t want the boat swinging around while Matt is trying to “hold on.”  Next, we zero current and shallow waters.  If something is dropped, we want to be able to see it and retrieve it right away.  And lastly, a sunny day with no rain is preferred.

Preparations

There are lots of things needed to prep.  We dig out the hooka.  What is a hooka?  It’s an underwater breathing apparatus that is operated by a 12v charge.  It is similar to scuba gear but does not require a large tank or BCD.  Matt connects the hooka to a battery and it provides oxygen for him to breath while underwater.  We also prep a bucket, tools and spare zincs.

As an underwater mechanic you need something to put your tools and parts in while underwater.  Matt ties a line from the boat to the buck and submerges it underwater.  He can then put his tools and parts inside the bucket thus reducing the risk of losing them to the sea.

Here is Matt all suited up, the hooka connected to the port engine and the bucket before and after submersion.

The Prop

We have two volvo folding props.  We can change the small zincs without having to disassemble and remove the entire prop.  However, in order to get to the larger zinc we have to disassemble and remove three small 1” screws, 3 axels, 3 zincs, 3 blades and the hub just to get access to the large zinc.  Yep, all underwater.

The Process

Our specialist, the underwater Mechanic, gets started.

First, Matt removes the first small screw, places it in the bucket and then removes the first axel. Middle photo Matt uses the end of the alan wrench to push the axel out. Once these two items are removed the first blade will come off.  Great!

On to the 2nd blade.  Using the same method our underwater mechanic uses the allen wrench to remove the screw, then the axel and then the blade.  This looks easy peasy!

I spoke too soon.  Matt removed the screw (top photo) and used the allen wrench to try to remove the axel.  The first two just look a little tapping.  After several minutes matt starts “jamming” it in with more force and still the axel does not budge (look at his white knuckled fist on lower photo)

He goes to his tool chest for a different tool.  Searching in a black bucket underwater can’t be easy.

Stuck Axel

He grabbed several tools trying to get the axel out – on both sides.  Even using the rubber hammer on each tool he still couldn’t get it out.  He even tried using a clamp and that did not work. Imagine how fun it it so try to hammer something with the water preventing you from using full force.  Poor thing did this for well over 45 minutes banging his fingers several times.

He was relentless on this axel which would not budge. 

After two leg cramps and exhausting all thoughts on how to remove it, he decided to try another time.  So, he put everything back on and called it an exhausting day.

Second Time is Charm

Matt put on his underwater mechanic hat a week later with better success.  He found a spare axel and started with the troubled axel first.  Coming at it fresh, with a better tool allowed him to finally remove the stubbornly stuck axel and prop.  The other two were fairly easy as they were last time.

He brought all the pieces on board to clean and reassemble.  The top photo shows you three things.  The green arrow points to the hub or the main part of the prop.  The blue arrow shows you an axel and the red arrow points to the used large zinc that is being replaced.  The bottom two photos show new and old zincs (large and small).

Matt cleaned up the hub, removed all barnacles, growth and corrosion.   The middle, left photo shows you how small the screws are that Matt has to handle underwater.  The bottom left shows you the size of the axels and the prop blades.  The bottom right photo shows you the numbers that Matt has to match up to the blades. The #1 blade goes in the #1 spot.  Keep in mind, this is all underwater!

After everything was cleaned and assembled in the cockpit he went back underwater to finish the assembly.  The large zinc first, then the hub, then blade #1, axel #1, and screw #1.  Once secured, he repeats the process for blades 2 and 3. 

Project complete!

Nirvana in the Middle of Chaos

We had been quarantined on our boat now for 2 weeks.  We have another 10 days to go as the FP government extended the quarantine for the country.  There are 37 cases hundreds of miles away from us.  Currently there still are zero confirmed cases in the Gambiers.  However, despite that good news, we still are living in about 600 square feet of livable space.  We are still anchored in front of Totegegie (the airport island).  So how did we find nirvana in the middle of all this chaos?

My friend Stefan is a local who I met last year during the Gambier Cultural Festival.  He carves the pearl shells and makes amazing jewelry using pears and the oyster shells.  He normally lives on Mangareva.  However, he moved his entire family to a remote island called Puaumu which is one of the northern most islands in Gamblers.  There are no inhabitants on this island.

Stefan had invited us to visit his little piece of nirvana but we wanted to wait until the full two weeks had passed. Even though we are still technically in quarantine, we thought we could take the risk by exercising precautions (staying 6’ away, no hugging or touching).

Setting up Camp

We could see a small metal structure as we approached the island.  Interesting enough they did not use this structure at all as it was pretty run down.

Stefan had the marinated chicken on the grill when we arrived.  His wife Manu had a feast set up on the table.  They had large tarp with two 3-people tents set up underneath.  There were 10 of them living here for the past 3 weeks.  A small kitchen/dining room set up on the beach overlooking the turquoise water lapping the shore.

Stefan's Campsite

The table was packed with food including a rice, pasta, chicken, poison cru (fish), sashimi, and banana bread.  The fish was caught the day before (bottom left photo) and was used for the sashimi and poison cru.  The banana bread was baked between leaves on the grill and was scrumptious.  The chicken had been marinated for a few hours and was incredibly juicy.  Everything was so tasty.  I cannot believe the went through so much trouble for lunch for us.  Keep in mind they have very limited supplies and resources as they are living on a deserted island in quarantine and yet they shared what they had with us.

Exploring Nirvana

After lunch Stefan showed us how to fish using natural resources.  All of the islands are covered in hermit crabs.  Millions if not billions of them crawl around each island.  He showed us how to lure a crab out.  First you whistle to it and it slowly comes out.  Yep, you hold it close to your mouth and whistle any toon and out it comes like a genie from a bottle.   You patiently wait for him to get mostly out and then quickly grab his body and slowly pull him out.  Gentle tug, you cannot pull too hard as you will rip his tail part off and that is the part you need to fish.

You tear the tail part off the crab and feed the crab to the sea (fish).  Attach the tail part to a small hook, which is attached to a string which is attached to a large tree limb.  Toss the hook into the shore and reel in your catch.  This entire process yielded us this beautiful trigger fish in less than 2 minutes.  We tossed him back as he is not edible.

We enjoyed a nice leisurely walk around the island which actually has sand (not coral and rocks) on the shore.

This little nirvana is a bird refuge with lots of baby birds.

When we returned, the ladies were watching a movie (yep on a mac, in a tent, in a deserted island).

It was hard to say goodbye, but they sure showed us with true nirvana is like during this time of chaos.

Graveyard: Island’s Windward Side

The wind shifted and forced us to move to a more protected anchorage near Totegegie. This sweet, skinny island is where the only airport is located in Gambiers.  It is a long, slender island with the leeward side in the lagoon and the windward side facing the ocean.  Most islands with a “windward” side facing the ocean are breeding grounds for a graveyard. What do I mean by that?

The ocean carries all sorts of things that are dumped or discarded by humans.  It is no fault of the ocean, but typically that stuff will land on an island that faces the ocean.  Totegegie’s windward side is no exception.  The photo below is a snapshot from our Navionics app which shows Totegegie.  The bottom left side is the lagoon side, the red arrow is Sugar Shack, and the top right is the Pacific Ocean.

The lagoon looks unattractive because the chart shows all the coral heads (bommies), depth, and channel markers.  But in reality, this is what the lagoon looks like in front of Totegegie.

Technically, we are not supposed to partake in any water activities which include swimming, SUPing, kayaking, etc… during the quarantine period.  In fact, we are not technically supposed to move the boat within the lagoon to other anchorages either.  However, the authorities have allowed us to move the boat to accommodate the shifting winds in order to keep the boat safe. 

Breaking the Law

We have been going stir crazy staying on our boat for the past 11 days and needed to stretch our legs.  So, we were naughty!  We blew up our paddle boards and went to shore.  Since the airport is closed on this uninhabited island — maybe it is not terribly illegal. 

We tied the boards to a tree and exercised our right to move our legs.

We walked up a little inlet that becomes a small river during high tide and then dries out during low tide.

The Graveyards

We encountered several different “graveyards” on the windward side.  Using the descriptor “graveyard” is sad and gloomy, but so was the site we encountered on the windward side of the island.

The Boat Graveyard

First, the steel graveyard.  The French Military used this area as a dumping ground many years ago.  They dumped tons of steel and did not account for the eroding shore.  Now the steel is all exposed and hiding in pain sight. Lots and lots of steel parts, poles, and pieces were scattered along the coast.  So very sad.

The Fishing Trap Graveyard

The next graveyard was full of fishing beacons and traps.  The Chinese use these large fishing contraptions and beacons. The locals use rods and reels.  These bad fishermen build the large fishing traps using bamboo and string.  Attached to the float is a beacon which allows the fisherman to find the trap at a later date.  They attract fish by tying plastic bags full of food to the bamboo and they let the trap float in the ocean (see the center photo with the bags still attached).  This is equivalent to deer hunting from a blind – not a sport!

Parts to Fishing Traps

The beacons seem to detach themselves from the traps and liter the beach as well.  We found three beacons in a mile stretch of shoreline.

The Trash Graveyard

As you can imagine, there is lots of trash, especially plastic on the windward side of the island.  We unfortunately do not have space to store the trash on the boat, otherwise we would have collected it.  All I could do was toss it further up shore to prevent it from being swept back into the sea.

The Animal Graveyard

Lots lobster shells laying around. Hopefully, it is just their shell after they shed them and not the death of the tasty lobsters.  We came across a perfectly intact crab with his 10 legs and eyes sitting on a rock.  Then a few feet away were a gaggle of crabs feasting on a dead bird.

Our walk on the windward side led us toward the airport over lots of dead, broken coral and rocks.  We had a few small patches of sand, but for the most part it was a rocky shoreline.

The Airport Graveyard

We finally made it to the airport!  It was not that far, but it took us awhile to navigate the uneven ground.  Me posing near the wind sock at the top photo.  An eerily empty airport and Matt walking along the “road” that runs parallel to the runway.

I had always wanted to walk down a runway.  Why?  Who knows?  Just a silly thing really.  But I loved it!  Maybe because I am a law abiding citizen and this was illegal – or maybe the pending danger of a rogue plane flying in??

We enjoyed a lazy day after we got back to the boat.  A little sunbathing and a few small boat projects.  Here is our view of Totegegie during our quarantine.

This is the inlet we walked up to get to the windward side of the island.
