The first E-PWC concepts did already show up in 2010 from Green Samba and Eco Watercraft. Both never made it to the market.

If there is one annoying thing about a personal watercraft (PWC) it is the noise. Even from kilometers away people are complaining about the loud engines and this why more and more places ban the Jetskis. A solution for this would be an E-PWC which is a Jetski with electric engine.

Petrol powered PWCs have with 200 horsepower or more a lot of power. You can compare the performance with a sports car. So much energy needs huge batteries which make them very heavy. On top of this the batteries and electronics for an E-PWC need to be salt-water-proof. That’s a tough challenge which electric cars do not have to resolve. This is the reason why we have not seen any electric personal watercraft come to market yet, although innovative startups have tried it since 2010. Let’s look at 2 examples.

E-PWC Green Samba

In 2010 the Silveira Group from Ohio in the US presented a prototype of the Green Samba. Their promise was to deliver a similar experience than a 200+ horsepower PWC with speeds up to 65 mph (105 km/h), just without the noise and with no local emissions. The company never announced a price and the product never was available for purchase. Nevertheless the concept was very interesting. Not only because it was electric, but also the shape and the weight was very different compared to other Jet-skis. The light weight carbon fibre hull was designed that rider was sitting very close to the water surface. Almost like a race motor bike.

The Samba Green prototype was scheduled for late 2010, but the company stopped the efforts as they realized that the battery technology was not advanced enough at the time to compete with the performance of petrol powered Jets. Already in 2009 they had prototypes of the Samba which was a petrol powered version of the Samba Green. See the following video:

The Silveira Samba Green website was originally at silveiracustoms.com, but it is not online anymore.

Eco Watercraft

Another company came up around the same time with an environmentally friendly PWC concept. The Eco watercraft approach was again about eliminating noise and local emissions. The charging time was claimed with 3 hours at 240 volt and 6 hours at 110 volt. The first prototype reached 50 mph (80 km/h) according to CEO Barret Taylor, but the goal was 65 mph (105 km/h).

The company compared their E-PWC with Tesla cars and promised instand torque at any speed. Nothing was said in terms of run-time at the time about the lithium ion battery powered Eco Watercraft. Their goal was to find a well known big wave surfer to proof the concept that their Electric Jetski would be able to compete with petrol PWCs. Also their original website ecowatercraft.com is down.
