Thanks for your input, Ken.
Your experience lines up with most of the results that have been reported by various members in this group for the 10 years that I've been participating in the discussions here. That said, my 30' ketch with 10,000# displacement draws about 1488w at 4.4 kts. (about 5mph) which translates to 19 nm (22 mi.) range with my 8kWh (160Ah x 50v) LiFePO4 battery pack (80% usable). I have posted measured performance data a number of times that supports these numbers.
However, the linked sale listing mentioned a 70 mile range at 5mph in a 21' launch with Ray Electric outboard conversion. That claim could be possible, the questions that I asked of the seller will help confirm that claim.
Fair winds and smooth seas,
Eric
