Epic has a new electric boat.

I\'m not sure this is going to catch on.

Figure the weight and cost of batteries it may not be a great deal.  Plus, hybrid cars use regenerative breaking to extend the range, but this is not going to work well in boat where you typically expend energy to stop.

Figure each battery adds weight that will reduce the cargo/people capacity of the boat.  Yes it is ballast, but unlike water in tanks you will have to add additional floatation to meet the standards.

As for the claim it reduces the carbon foot print.   That is any easy thing to claim, but can they prove it.

If they had to include all additional energy used to produce the boat over a standard model, how long would I have to run the standard model to equal the differnce?   To truely look at the enviromental impact, and the carbon foot print we would need to include the additional energy need to produce the boat, including;

Batteries
Floatation
Hull
Motor System and Electronics(to control the drive system)


Just something to think about. :whistle:

I\'m no scientist, but I hear on the wakeworld forum that... electric powered = more torque = more capabilities with ballast

true?  :dontknow:

In a full electric drive (DC Electric Motor), torque is a function of the voltage and current flow, and the motor design.

It is possible to slow the motor down and still generate the full torque capability.  Unlike the traditional V-8 which the torque generated follows the RPM curve, the Electric motor can be controlled to generate the same torque at all speeds.  Additionally the electric motor could be smaller than the V-8, until you add the same engine to complete the Hybrid systems, and the batteries.

I think this may become very viable if there is a break through on the battery technology.  We need smaller and more energy storage per pound out of the battery.

Is this boat worth buying?
