Trip report on the Yamashiro

cedricverdier · 21st July 2006, 03:13

Hi all,

Just a quick post to let you know that we managed to dive on the japanese Battleship HIJMS Yamashiro sunk with her sistership the HIJMS Fuso in the Philippines.

People normally speak about the size or the beauty of a shipwreck. For me, amongst all the wrecks I explored in the last 20 years, the Yamashiro is clearly the most unfriendly wreck: extreme depth (195m on the bottom), ripping current, bad sea condition, total darkeness, extremely remote location, logistical nightmare, lack of recompression chamber, etc.

So please enjoy the trip report here:

or a pdf version at www.cedricverdier.com/articles.html

... and don't even think about going there!

Cheers

Ah Cedric you make me so jealous that I wasnt with you on this one.

Theres just something expeditions which makes them so much fun - maybe its all the challenges not just the diving ones and overcoming them.

Sounds like this one was a real challenge - I can well imagine the conditions. That makes it even more of an achievement

Well done to you all.

Now as Jerome so correctly states - lets stick to the deep caves! - deep wrecks are much harder work and more dangerous

PS Ill see you guys tommorrow I land at 3pm should be at Subic by 5:30pm
How much sorb do you guys have left over? Im going to need maybe 10kg for the week. I can bring some if needed (and pay excess) but if you have plenty no point.

Hi Cedric

Congratulations to all seems like the trip was quite eventful glad you fulfilled the objective after all that planning and preparation. I look forward to chatting about the experience are you able to share any info on the schedule was it
VPM B/E with added conservatism? Or was it modified specifically for the dive.

Cheers

Glad to hear you're safe, Cedric.

Likewise, I'm happy to find out about your sucess. Congradulations, yet again.

Your story telling is becoming spell-binding. Very good for a Frenchman.

He has some Swiss in him as well, mostly the holes in the head I think

Well done you mad Frenchman!

Simply amazing

Its really awesome to see (hear) that there are still people who set goals on the level that you have, work toward them, and achieve them!

Congratulations to you and the team, its simply an awe-inspiring account

Encore, toutes mes felicitations!

Congratulations Cedric, very well done! Glad you made it back in good shape, sounds like you had just enough luck and plenty of good support.
Very ominous all those different failures/problems, it must have been incredibly spooky being down there. You've got more guts than most.
Thanks very much for the report, and of course I'm curious about a few things-
Did you run out of O2 from the heavy exertion or was it just that long of a dive? I was assuming that you had at least 19cuft cyls onboard and that you pumped them up pretty high...
Was the current any less on the bottom? Were you able to find an area out of the current and free swim or did you have to pull yourself along over the wreck?

More likely it was the low pressure O2 fills they were forced to use because 'someone' wasnt there with his booster

Glad it worked out cos I would have felt a bit guilty otherwise

No bell???!

Logistical nightmare - would you do anything different next time?
