[PSUBS-MAILIST] R300 Dive at Lake Amistad

[Cliff Redus via Personal_Submersibles]

If you don't mind me asking, what was the cost for the car hauler for the
trip?

One other point on the OTS comms.  During the day we did a speed
calibration by towing the boat submerged up to 7 knots.  FYI  I found that
over 3 knots, we were unable to communicate with OTS gear.  When we slowed
the boats to 3 knots, we could reacquire comms.
