Projected speed is only in the 50s. But with Steve Curtis involved and Mercury Racing, it's only up from here! Gotta start somewhere!

Whoopdeedoo....

This is the future. Like it or not, its coming on hard.

Sad thing is sourcing the materials, manufacturing, usage, and end of life issues with all these batteries hurts the environment also.

No doubt electric propulsion has a place in the marine world but not for the boats you see on these pages.

A few years from now battery's will be much better, which will change everything

when the battery takes the same volume and weight of a gas tank does today,yes it will be a no brainer.
Thats a 20x jump from todays technology.

Well how do you explain the Cybertruck having over 500 mile range?

The weight of Tesla cars is 50% battery and 50% power train and body
Can you see an Allison with a 1200lbs battery and for most boats well over 50% of the all up weight added to the weight to go electric

The battery weight will depend on your desired range. And maybe not an Allison, but an LCB has a lot more area within the CG for extra weight while being able to stay on the running surface in comparison. Efficient hulls will benefit exponentially.

Range is a simple calc, multiply your gas weight by say 20x and theres your eqivilent electric range, then you have to fit that in your boat and volume difference is about 5x.
( based on 30% SI ICE efficiency and 95% electric) Large diesels are close to 50% efficient

So we need to build our hulls from carbon + nomex and have them on foils with sail assist

Am I the only one who feels high power electric power cels in a boat is literally life and death dumb?

**Smalltownbassin** · 09-22-2021, 05:54 AM

For racing....Cool idea. Battery cells can be swapped after every pull so weight and capacity can be reduced big time. Hell, if you can pull 1000amps for 10 seconds from a 100 amp hr lifepo4 thats all you need. Swap it out and go again. For a bass boat or river runner....nah, itll be a while before we see enough efficiency for that.
