Hi Geoff, it would seem nearly impossible, given the 800+ miles of not so predictable conditions, bypassing military bases, plant cooling runoff and intakes, shipping lanes, harbor entrances, piers, slight to extreme conditions, now comes the serious question...finding the small percentage of divers who would be ok navigating along the surf zone, and do fine in low viz! To me it's a very possible event from the experience of diving with hardcorediveteam the only things that have made us call any dives were tsunami warnings and hurricane swells were predicted couple weeks ago. We actually got in the remnants of late august hurricane swells, but went in anyways. At this very time there's divers getting the distance data that's comparable with caving at 1/2 mph..and thinking to use that as a reference taking into consideration diver differences. We get over nautical mile easy on 80cf tanks without trying for distance. I know it's gonna vary in extremes. Also I doubt there is gonna be any Ironman class of someone attempting to dive the (whole) coast, as much as I would like to try. Now the 40 nm dive that's scheduled in October 2011 in Monterey Bay is gonna determine alot, I was suggesting it to be completed in one day by legs of 4 or 2 miles, if 4 miles then 10 teams of 2 divers (+one extra team)with 10 kayaks carrying tanks, gps and sound device in case someone is heading out to sea in a bay. So 32 divers (22 divers + 10 kayaks(divers) all get in the water same time and complete the gps leg of 4 miles to where the team ahead started from...done deal. Instead it's gonna be a relay fashion of point to point taking like 2 weekends. Now thinking about the statelong dive as a relay, I'm guessing without even calculating anything it could take up to 200 to 400 days!! Media would get bored with that. This whole idea was born out of an ambitious desire, it's never been attempted. And so far it's grown to far reaches of interest nationwide. I'm a key contact person, organizer for LA county. As time moves on, there's gonna be a whole lot of help in LA county alone to push this project through. If you have any reasons to network with divers about a business or just diving, this is gonna be huge for that. You see all the contributors already on the webpage. I'm in the process of getting local environmental fund raising agencies, fishing groups, or any that want to jump on this involved. I think it's gonna be fun. If you're not already part of this, get in now and be a part of it. What you have to say in orgaizing it, may be what the event becomes founded on. Think about this, the largest diving event in history and you personally put in the ideas that helped make it possible....THAT would be pretty awesome! I plan on diving the entire PV peninsula for this, possibly if I can. I know HCDT will be right there on this! Possible land support may be funding the gas needs. It's up in the air and a major business opportunity for lots of companies.
