Dive Buoyant

Buoyancy An Art or Skill?

Buoyancy is something you have to constantly practice and perfect while diving.  It is not something you learn once and then move on as there are so many different variables.  The water depth, tank weight, BCD, weights, and your breathing all impact your buoyancy.

My new BCD has helped tremendously.  The original BCD was a unisex BCD which did not fit me correctly.  The torso was too long and it sat below my hips and was overall just too big.  I sold it and bought a female Aqua Lung Pearl which fits much better and gives me far more control.

I am pretty flat (or neutral) while I am diving.  But I do tend to struggle when I want to stay in one place to take a photo, look at a critter, or wait for other divers.

Work needed to be done so I jumped at the chance when Eric on “Ad Astra offered to do buoyancy skills with a few of us.  Eric is a dive instructor and has over a dozen certifications (rescue, first aid, deep, technical, side mount, etc…) and is the perfect person to teach us new techniques.

Me, before I learned my new skills, pretty neutral.

Jane from “Cheetah II,” Daryl and Janet from “Maple” joined me at “Ad Astra’s” mooring where Eric had rigged a little skills course.  He put up a diagonal line creating a space that got smaller as the line met the sea bed on opposite side.

Eric had us practice fin kicks where you leave the tips of your fins on the floor and raise your body up with an inhale and down with an exhale.  After we “mastered” this exercise, he showed us different fin kicks.  Most people do the flutter kick which tends to kick up sand and can disturb the sea life so we were learning alternative kicks that are less disruptive to the animals.

Types of Kicks:
  • Flutter kick
  • Modified Flutter kick
  • Frog Kick
  • Helicopter turn

After displaying our new skills, we used the modified flutter kick to get under the line, then helicopter around and swim back under the line without touching the line or the ground.

Next, we used the same kick to swim barely over the line, then we headed straight down (perpendicular to the ground, head first), then swam under the line belly up (tank closest to the ground).  Of course, I looked at him in disbelief when he demonstrated it and indicated I might not be able to do it, but to my surprise, I killed it!

The next skill I had heard about and swore I would never do – but here I am preparing to do it in front of 5 other people.  You swim slowly, just above the floor (18″), up to a spoon that has been buried in the sand (the top part of the spoon showing).  As you slowly approach the spoon, you gently nudge it with your regulator, then slowly and calmly remove your regulator, grab the spoon with your mouth, look at Eric, and then replace your regulator.  I am not sure what the spoon’s problem was but it kept evading my mouth or jumping out of my mouth- it was comedic for everyone but me. Goin in, miss, goin in again, miss, spoon flops on sand – try the entire move again.  Eventually, I got it, but man it was irritating.

For the last skill we slowly swam up to the mooring, 18″ off the floor, hovered at the mooring for 5 seconds.  We then used our breath to raise up over the mooring then headed upside down, holding for 5 count (basically doing a “U” around the mooring.

When we came up to the surface, we were all surprised to learn that we had been down for 90 minutes!  It was an incredibly educational and useful session that we are all very grateful to have received.  It certainly should be included in the basic Open Water or at least in Advanced training – which it is not.

None the less I feel much more equipped to handle my buoyancy and look forward to putting my new skills to work while diving.

Wreck Dive: Hilma Hooker

Wreck diving. Typically I am not a fan of wreck dives as they make me really sad to think of the overall loss of life, cargo, and ship. But then I learned the history of the Hilma Hooker wreck and I decided to make an exception.

How the Hilma Hooker sunk according to Wikipedia: In the summer of 1984, the Hilma Hooker had engine problems at sea and was towed to the port of Kralendijk, Bonaire. It was already under surveillance by drug enforcement agencies. Docked at the Town Pier, local authorities boarded the ship for an inspection when her captain was unable to produce any of the requisite registration papers. A false bulkhead was discovered, and held within was 25,000 lb (11,000 kg) of marijuana.  The Hilma Hooker and her crew were subsequently detained while the local authorities on Bonaire searched for the vessel’s owners, who were never found.

The ship languished under detention as evidence for many months and through general neglect of her hull she began to take on considerable amounts of water. It was feared that she would sink at the main dock on the island and disrupt maritime traffic. After many months of being tied to the pier and pumped of water, on September 7, 1984 the Hooker was towed to an anchorage. As the days passed, a slight list became noticeable. The list was even more obvious one morning.

The owner was still not coming forward to claim the ship and maintain it so the many leaks added up until on the morning of September 12, 1984 the Hilma Hooker began taking in water through her lower portholes. At 9:08 am she rolled over on her starboard side and, in the next two minutes, disappeared.

The Hilma Hooker came to rest on a sand flat between two coral systems in an area known to divers as Angel City. The wreck has subsequently become a prime attraction for scuba divers. It lies in approximately 100 feet (30 m) of water and at 240 feet in length provides ample scope for exploration.

However, rumor on the island was that the local government did not want to sink the boat, but locals did.  The locals believed this would make an excellent dive site.  So, at the dark of night, several locals brought the listing boat in between two reefs and “assisted with the sinking process” with the hope that she would sink straight down on her bottom.  Unfortunately, she was listing so bad that she sunk sideways and landed on her side hitting part of the first reef.

Hilma Hooker is 72 meters (236′) long and 11 meters (36′) wide.  Her stern is about 21 meters (69′) below the surface, the bow is 26 meters (85′) below and the mast is 30 meters (100′) below.  Her original name which can still be seen on her transom is “Williams Express” from Panama.  There are two large open holds, but you are required to be certified wreck diver to swim in and around the interior of the wreck.

Being so far down, 29 meters (95′), I was content hanging out around the exterior of the wreck.  Remarkably, I found some of the most interesting aspects to be on her bottom (where coral and sea life hung precariously to the bottom of the ship (upside down).  It is also where we saw a giant green moray eel and several trunk fish.  Many sponges and hard coral grow on the bridge and lots of little sea cities can be found all around the ship.

Since this was such a deep dive we did not bring the GoPro to take photos, so the images provided were taken by other photographers, credit give on each photo.
