Doug
The lawsuit you refer to, was it the WPB 3 accident in FL . If so can you 
confirm the statement below that was emailed to me in private about the 
court case. How accurate is the info below.

 >The triple death in WPB well the instructor is an or was an excellent 
instructor and unlike what xxxxx states he did not smoke and he was not a 
drunk. He was a retired sgt Major from SP and had 4 tours of duty in Nam
He went through swim school with the USN in February. He ran the US Army 
swim Scholl for a few years.
He swim 2 miles 3 times a week up until the day he died and he ran for 20 
minutes on the non swimming days .That comes from years of combat swims
He was an excellent diver and an excellent instructor.
xx was the expert witness against him or his estate the testimony is 
interesting. Unfortunately the insurance company settled for 450,00 instead 
of going to court as there is no doubt in the lawyers mind and evidently in 
their that the case would have been beaten.xxxxxx per se had been dropped 
out of the case 3 months earlier and the suit then was against xxxx estate, 
xxxxxxxxxxxxx, The boat Captain and the diver who tried to assist in the 
rescue until xxxxx sent him up because he was low on gas. . The suit had 
been for 9 million originally. The offer for 450,00 was made as that was 
the amount the insurance company figured they would spend in appeals once 
the plaintiffs lost the case. And that offer was put on the table at 
mediation called for by the plaintiffs attorneys the day before the case. 
The attorney at hat time had only offered them 50 thousand (basically the 
cost of a trial) So at 4 PM the offer was made and it was to be taken off 
the table at 8:30 PM at 7:50 xxxxx called and they took it.
They then went to court against the diver (xxxxxxxx) who survived with xx 
testifying against him. Had they won this case that would have meant 
whatever you do do not try and rescue a diver. Fortunately the jury found 
that xxxxxxx efforts only helped the situation not contribute to it as xx 
was implying. Then the judge threw out the suit in regard to xxxxxxx the 
3rd diver who died. xxxxxx was a close friend of xxxx but when they had a 
problem he had left and went up to deco on his lift bag. The last time 
xxxxxx saw him he was on his lift bag. He may have gone back down to assist 
or he may have had a problem of his own. He was not a student or anything 
that nature. He had not been with them on the three times they got up to 
150 and then sank back to 200 plus before xxxxx left.
As far as config there was a complete video of xxxxx xxxxxx taking the same 
equipment that was used by the deceased and ascending just using his BC. 
Then they have a scene with xxxxx ascending with four steal stages just to 
show that the BC would lift that much more.
Now I understand that they are making an appeal against the boat captain 
because he has no insurance so will not have a lawyer to represent him. No 
they will not get any real money but they can set a example they could use 
in future cases against boat captains in similar situations. or any 
accidents for that matter.
Thought you might want to know more about what happened than what is stated 
on tech diver
