Kier,
 
Your folks are welcome to spend the night of 6 July aboard REVELLE.  
Please understand that we will not be serving meals except for 
dinner on the 7th before the ship sails.  Also, most of the crew 
will be off the ship so the normal emergency teams will not be on 
hand although we have a guard at the facility who tours the ships 
every half hour.  We ask that anyone spending the night in 
situations like this clean up after themselves and not put 
extra burden on the crew.
 
Only thing I need to know is what the total number staying 
on board will be so I can pass it to the guard and Captain.
 
Tom Althouse
Marine Superintendent

Rose,  I spoke to Christian.  The slack tensioner (CPM request to S. Shor)
can be tested on the .068 wire on Melville rather than the F/O cable on RR.
We went over the RR schedule and he is convinced we should keep K. Becker's
two cruises on  Melville.

Christian, Tom -
There is sufficiently high probability that I will have $36K +
remaining in the shipboard equipment account this year that
I believe it is worthwhile for you to submit a supplement request
at your earliest convenience.

Good questions, yes the planned use in scheduled for Melville in 2000 and
2001 although a ship with a winch capable of handling 0.680" electro-optical
cable would be preferable.  I don't have answers for you yet and I'll bring
this up with Fred Spiess and Keir Becker.
