The electric engine of e-motion can get the sportboat up to roughly 30 mph.

Tahoe has long been a favorite playground for boating enthusiasts, but over
the last month and a half, one boat in particular has been turning heads
around the lake's western shores.

Its sleek, custom shape automatically separates it from any other boat on
the water, but what goes on inside its hull is what really makes the
Designboats Tender 06 sportboat — named "e-motion" by its owner — special.

The 20-foot sportboat doesn't depend on a traditional combustion engine,
instead it's electrically propelled across the lake without any emissions by
a Torgeedo Deep Blue 80 — an 80 horsepower equivalent electric outboard
produced by Torgeedo Gmbh of Germany.

With instant responsiveness from the throttle, the boat zips up to 30 mph
without any lag. The Tender 06 can accelerate so quickly that there's a
button for "slow mode", which remaps the throttle so it doesn't apply full
power — a feature helpful in maneuvering around the dock.

While boating at top speed, the deafening sound of a combustion engine is
replaced by the quiet whir of gears and sound of air blowing past, resulting
in a unique experience of moving across the water at a high rate with enough
quiet to hold a conversation.

The Tender 06, "e-motion," first came to Tahoe last August, and is owned by
Herbert Schlafter, of Zurich, Switzerland, and Sausalito, Calif., where he
usually keeps the boat.

Ruckmarine Electric Boats, of Truckee, facilitated the process of bringing
the electric boat to Tahoe for the Concours d'Elegance boat show, after
which the Tender 06 was housed at Homewood High and Dry Marina for another
month in order to allow prospective buyers or anyone interested a chance to
check it out and take a ride.

Scott Ruck, owner of Ruckmarine Electric Boats, said the company has been
delivering a variety of electric sportboats to Tahoe over the past five
years, and is focused on bringing clean, zero-emission, zero-effluent
electric boats to the lake.

While rare on Lake Tahoe, electric boats are much more common in Europe,
according to Ruck, with several European lakes now restricting access
exclusively to electric boats.

During the Councours d'Elegance show, the owner of Designboats and builder
of the Tender 06, Peter Minder, made the trip from Europe to be on hand for
demonstrational outings on the lake.

During that time, Ruck said that Minder explained several European
waterfront businesses are in competition to provide dockside charging for
electric boats in order to attract customers, creating an environment where
boaters charge up over lunch or dinner, and then head out for more time on
the water. It's an idea Ruck said he envisions taking hold along the shores
of Lake Tahoe with its many restaurants and businesses.

As an example of battery usage, Ruck said a high speed cruise from Homewood
Marina to Tahoe City for lunch and back, with four people on board the
Tender 06, would require 2.5 hours to fully recharge the batteries.

The Tender 06 holds five people, and its BMW i3 batteries allow for several
hours of cruising without a charge.

The boats also don't require a charging station like electric cars. Instead
they are equipped with everything required for charging on board, so the
only thing needed is an outlet. The Tender 06 is configured for charging at
240 volts but can also be charged at 120 volts.

After a simple charging process, the electric boat is ready to hit the
water, producing zero emissions on a lake where water clarity is one of the
top concerns.

Another benefit of the Tender 06 is when it comes to hull inspections and
invasive species.

"It's much less complicated than a gas powered boat," said Ruck. "The whole
cooling system is much simpler. Inside of a combustion engine you've got all
kinds of areas where muscles can accumulate."

At first glance, one might take the boat for a concept sportsboat, but the
Tender 06 is a production boat, which can be purchased with a full warranty
and support from Ruckmarine, Designboats, and Torgeedo. The price of a
Tender 06 is roughly $150,000.

Designboats also builds a Tender 08, which is 26 feet and has dual-inboard
electric drive systems. The Tendor 08 can carry up to eight people.
