Ben,
I do not think it would be a problem in re electrocution. I sunk a 60v powered boat and did not feel a thing. I was using lead acid at that time and it went straight to the bottom in 40 feet of water. The batteries were sealed agm's and most took a charge when raised about 9 months later. The short circuited current is going to travel across the battery terminals or across the motor connectors, all very short distances.
The major caution should be that you are not held too tightly in a cockpit. Mine was an open canoe at the time. My present boat is also open and has nowhere near enough flotation. She would go down pretty fast since she is carrying about 500 lbs of LiFePO4 cells, 19 kwh.
Where are you located and what hull configuration are you planning? My email is mailto:nedfarinholt@comcast.net Hope you can get here for the race on Friday, Oct. 9. It should be a blast as we have 11 confirmed entries, some of which are pretty exotic.
Best wishes,
Ned

Hi all,
I have been designing a boat/system for the Wye Island challenge and had some worst case scenario thoughts.
I am running about 100 volts of lithium batteries, and if the boat were to sink, could close proximity cause electrocution?
Best,
Ben
