To: techdiver@terra.net
Jim, Are you sure you don't dive in
Southern New England?

DITTO,DITTO - Right On Jim - I can't beleive
anyone would use an anchor on a wreck.
We always deploy a graple.  Read Jims note again.
This works and is the only way to go.

i locate the wreck with sonar and drop a jug OFF one end of the wreck.
i go down the length of the wreck to locate the other end and drop another
jug
now i have BOTH ends marked away from the actual wreck
i now can go right down the middle of the wreck if i want,
 if i know which way it lays i can get to within 30% of the bow or stern or
midship
the ground tackle is 1/2 nylon med lay 3strand 10 feet of proof tested 3/8
chain
with a 5 tine ss grapling hook.
the chain and ss hook will be enough weight

as soon as the hook sets a diver goes straight down the line to lock us in.
he carries with him a piece of line about 20 feet coiled up with a beaner ant
each end
once he get to the wreck he CLIPS one end to the chain and he LOOPS the line
thriugh the wreck and back to the BEANER. the boat is now made fast with the
hook and also the "jumper" IF the hook pulls loose,,,so what the jumper will
hold. 
the strength of the jumper is determined by the size of boat/wind
/waves,current.
i usually use 1/8" parachute chord. remember it is DOUBLED so the force to
tear it is also doubled. when the last man is at the hook...he pulls it off
the wreck.....

BINGO we are now held to the wreck with the jumper only....no sweat  just
decompress and get in the boat. when everyone is in the boat all gear
stowed,ladder up ...o2 
wrapped up etc. ...time to go////throw a few revs into the engine and it will
strain a bit
throw a few more in and BINGO!!!! the jumper tears..."hook,,, line,,, and
jumper come right up for another day...all i do is tie a knot in the tear and
use the jumper over again..
i suggest replacing jumper after 10 tears.... i have not lost any ground
tackle in at least 15 years using this method...i have used this method when
maybe a few times we should have not been diving....let alone on the water
because of waves  
my $01 worth
