“That's an opportunity to Provide power back to your house. So again, not necessarily at the grid level, but that is a tremendous amount of battery capacity that could power your house for a week without you doing any sort of finagling of electric loads.”

The claim, plainly

An electric boat's battery pack contains sufficient capacity to power an average house for a full week without active energy management.

a quote alone can be ambiguous, so this restates it with the references and context of the conversation around it resolved. AI-written; the tape below the player is the source.

Assessment

The claim is true for high-capacity electric boats, such as those made by Arc Boats (co-founded by Mitch Lee), but false for standard or median electric boats. According to U.S. Energy Information Administration (EIA) data, an average U.S. residential household consumes approximately 28.8 kWh to 29.6 kWh per day, requiring 201.4 kWh to 206.9 kWh for a full 7-day week. Large electric boats equipped with 200 kWh to 232 kWh battery packs (such as the Arc One and Arc Sport) do have sufficient capacity to power an average home for a week without load management. However, industry survey data shows that the median battery capacity for recreational electric boats is roughly 60 kWh (with standard 7-meter boats ranging from 40 kWh to 80 kWh), which only provides enough energy for approximately 2 days of standard household electricity use.

According to U.S. EIA data, an average U.S. household consumes roughly 201.4 to 206.9 kWh of electricity over a 7-day period.
The median battery capacity across recreational electric boats is approximately 60 kWh, providing roughly 2 days of average household electricity.
High-capacity electric boats, such as Arc Boats models with 200 to 232 kWh battery packs, possess sufficient capacity to supply an average house for a full week.

Prediction Not checkable as stated

Next-generation boaters will be banned from using gas boats on waterways

“I think something that some people don't necessarily think about is the next generation of boaters will not be allowed to use gas boats on our lakes and rivers.”

Opinion

Gas-powered boats are an absolute nightmare to own

“Gas boats are so much fun to be on and an absolute nightmare to own. And awful for the environment, particularly when it comes to not just air pollution, but water and noise pollution.”

Recreational boats consume more fuel per mile than fully loaded semi-trucks

“Recreational boats use more gallons per mile than a fully loaded semi-truck. A fully loaded semi-truck might get six to eight miles to the gallon. A boat gets one to two.”

Disclosure

Arc One electric boat features 220 kWh battery capacity

“The ARC-I has Two battery packs totaling 220 kilowatt hours of battery capacity, which for reference is well over twice the size of any car that you'd find on, on the market today, like a Model S or Model X. It's identical to what you put in a full-size school…”

Insight

Fast charging is unnecessary for compelling electric boating experiences

“You don't necessarily need fast charging to exist in order to have a compelling electric boating experience.”

The Arc One electric boat operates more quietly than a sailboat

“We'll, we'll take an arc one out into a marina and we'll pass a sailboat and the sailboat will be louder than our boat.”
