[PSUBS-MAILIST] sea state

[Alan via Personal_Submersibles]

Emile,
we abandoned a dive in Snoopy 4 miles off the Florida Coast in what didn't seem like big seas.
It looked too dangerous to board. Although With your sail it would have been OK.
Next day we towed Snoopy out with Alec, Steve & 9 bags of ice for cooling.
We had to transfer them to the boat after the dive, & it was a bit tricky. The sub sits
in the water like a rock while the support boat bounces up & down around it. 
So you are in danger of smashing your hull on to the sub. We had 3 of us trying to
hold the boat off as we transferred crew.
Here is the video that used to be on psubs. The first few seconds show the surface sea state
which doesn't look too bad.

I would be interested in hearing how you get on.
Cheers Alan
