I think that Lightning truck could tow your boat 80 miles.
We Bet F-150 Lightning Range Is under 100 Miles with Heavy Towing (caranddriver.com)
That estimate is towing max, 10,000 pounds.
The pace of progress is faster than I expected even a year ago, I'm impressed with what I'm reading.
And the cost of electricity would be a lot less than gas costs.
No doubt it could tow it, but I'm not towing something 80 miles when the range is only 100. I'd want to have at least double the range I need unless I could stop along the way and charge in 5 minutes. Just like filling up my gas truck right?
But I seriously know that "filling up" will probably never be 5 minutes. Realistically I think a 15 minute fill up is much more reasonable, and the vast majority of people who stop at a gas station will spend ~10-20 minutes in there anyways using the bathroom, buying drinks/snacks, standing in line.
I think this is really the key. How fast can you "fill up" when you need, and how much range does it give you? One limitation is that the EV vehicles will (should?) always be heavier than their gas counterparts. They are heavier now, and as batteries come down in price they will continue to get larger and larger to have longer ranges. Conceivably you would really need a battery that is 2x the energy capacity that you have now to make an EV really competitive with gas cars/trucks. Once you can drive those suckers 4-500 miles without recharging I think that is the inflection point, as most people can't drive much further than that without stopping/breaking anyways. I know I can't.
For example, from Houston, TX (nearest metro area to me) it would be like driving all the way to Norman, Oklahoma without stopping. I just made this drive in April, I think we had to stop for gas 2x anyways. Or maybe we stopped to eat and use the bathroom. I can't remember now.
Data has always been sparse on towing kWh consumption up till now, I'm anxious to see what the numbers look like. For information purposes my father in laws Bolt gets 5 miles per kWh, or 20 kWh per 100 miles. Reports are the trucks are averaging 2-3 miler per kWh, so I'd expect towing moderate loads to be about .8-1.2 miles per kWh.
