Notes:

Did a Solo Kayak Dive today since the dive barge was not going out so that I could get some more measurements and compass headings so that I could complete my Mapping Project for the Divemaster course.

The south swell is really making diving off the south coast difficult this week. I got rolled 3 times on my way out to the dive site. Luckily once I was past the surf zone and out there it was much calmer. Unfortunately the visibility sucked which made it harder to work on my map.

Divemaster Mapping Project

As part of my PADI Divemaster training I am required to create a map of a dive site to teach me underwater mapping and reinforce the underwater navigation skills that I learned in the Underwater Navigator Specialty course that I took last month.

For this task I was allowed to choose Koko Craters, a popular dive site off the South East coast of Oahu. Because I dive this site very often, and had already started a rudimentary map of the location in the Underwater Navigator Specialty dives it would save me some time.

Normally the mapping project is done by a group of Divemaster Candidates (DMC’s) who collaborate on a finished map. Since I am doing this mapping project alone I would have to do everything myself, which would mean multiple dives at the location to get measurements, compass headings, etc.

Unfortunately we have been getting hit with a south swell for the past couple weeks that has made diving on the south shores almost impossible. Most of the dive boats have cancelled their dives and everyone is shore diving up at Sharks Cove for the past two weeks. In order to work on my map today I was forced to do a solo kayak dive in very rough waters.

I ended up getting rolled 4 times today while trying to get out to the site. Once I was offshore out at the site the seas were much calmer and I was able to get some diving done. Unfortunately the visibility was very poor for this location, normally we have around 100′ visibility at Koko Craters, but because of the south swell today it was only 10 to 15 feet, which made working on my map very difficult. There was also a strong current which also added to my challenge, luckily I had strapped one of my DPV’s to my kayak in anticipation of the strong currents and surge. Using the DPV I was able to overcome the current and get some work done on my map.

Here is the map I made of the Koko Craters Dive Site. Hopefully it will be good enough to pass and I can get signed off for this project. I don’t see how I can make it much better.
