Key Biscayne


A 4:30am start is always tough, but the wreck of the Jack-up Rig Key Biscayne is usually worth the effort. Our team's 'good weather fairy' Justin delivered again and provided us with great conditions despite being called off the dive at the eleventh hour due to work commitments.
That said, and despite the good weather, the trip out to the wreck had everyone on board dropping their breakfast over the side before we got to the wreck and there were some distinctly yellow faces as people geared up and dropped in.

The Dive

We motored down the shot line and then took a wide swing around the perimeter of the wreck enjoying the good (15m) vis to get a rare overview of the wreck site. We then hung around the central section of the wreck which is littered with meters of scattered drill rods and other oil rig paraphernalia exploring the crevices of the up-turned superstructure. Unsurprisingly the Crays were out in force, knowing as they do that this was the last day before the season begins. Its a given that by tomorrow they will all have vanished.


As we got into the latter half of our 30min bottom time we headed off down one of the three triangular legs now laying splayed out on the sand in 40m water. These legs are massive, 10m high and at least 200m long and make for a great scooter ride.
Once back at the main superstructure we took our time ascending to the shot line and into a slightly nauseous deco; the seasickness having not totally worn off on the dive.

  1. Thanks for the write-up and the footage, very helpful.

    What does 'ratio' mean?

  2. Divor,

    You are welcome.

    'Ratio' refers to the timing of our Ratio Deco.

    Ratio Deco is a technique based on standardised gasses which allows trained divers to calculate the required deco curve 'on the fly' without the need for reliance on a dive computer's algorithm.

    This technique is extremely powerful but it needs to be understood in context. It is taught in the GUE Tech 1 course if you are interested in knowing more.
