John,
I'm using the Winston cells and through my testing Peukert is nil so your range at those speeds and draw for 80% DOD would be.....
3.1 mph 19.5 to 21.7 miles
4.1 mph 7.6 miles
5.0 mph 4.3 miles
Cost of 48 volt (52 volts) bank @ 200 a-hr $3520.

Subject: [Electric Boats] C-30 with Torqeedo 4.0R
I've mentioned a couple of times about having mounted a Torqeedo 4.0 outboard on my C-30.
I got a chance to go out today, since it was a really nice (winter) day - Sunny, and upper 60's.
Here's the data from my run:
I only have a small bank of AGM batteries, so I can't run at high speed for very long without the voltage dropping off quickly. However, I ran for a few minutes at several different speeds, and recorded:
700-780W => 3.1mph
2000W => 4.1mph
3500W => 5mph
I ran about an hour at around 700-800 watts, and only depleted the battery from an initial fully charged level of ~54V (which quickly dropped down to around 48V), down to 47V.
The Torqeedo isn't a replacement for my Atomic 4, but is sure is a LOT quieter. And if the prices of Li batteries would come down, or if I could win the lottery, I could see myself doing mostly electric if I could afford about a 200Ah bank at 48V... :)
Have fun!
John
