Big power boost for torqeedo motors, batteries

Germany-based torqeedo definitely makes the most stylish electric boat motors available and is a leader in performance durability as well.

Now they have increased the power on their top-end Deep Blue line of inboard and outboard motors with the introduction of 100kW motors. The 100kW motors are comparable to a 150HP fossil fuel motor.

The motors come in two versions: a low-rpm version for displacement boats and a high-rpm version for planing boats.

More powerful batteries developed with BMW

In addition, the company has launched an upgraded, higher capacity 40 kWh battery that features 30% more capacity in the same footprint and an energy density of 144 Wh per kg.

The battery has been developed in the course of adapting BMW’s i3 electric car batteries for the marine market. Among other things, the companies are partners in the ‘Malizia’, a 60’ racing yacht being optimized for the world’s toughest solo sporting competition, the Vendee Globe in 2020.

The 30% increase in energy and energy density will also extend to torqeedo’s 24V batteries, used for their line of outboard ‘Cruise’ motors. Based on the new capacity, the 24V battery gets a new name: Power 24-3500, featuring an impressive energy density of 138 Wh per kg.

Indonesian eco-dive resort goes all e-boat

MahaRaja EcoDive in Indonesia

From Eco-Business

A new eco dive resort in Raja Ampat has become the first to launch e-boats, an important step in the race to protect the world’s most biodiverse coral reefs.

Competition is healthy among the eco resorts of Indonesia’s most famous dive destination, Raja Ampat. And MahaRaja Eco Dive Lodge, which only opened 8 months ago, has just scored an important claim to fame.

The small luxury resort is the first in Raja Ampat—and possibly the first in Indonesia—to electrify its dive boats.

MahaRaja has fitted two traditional Papuan long boats with electric engines, beating rival sustainability-minded dive resorts such as Kri Eco Resort, which also has plans to build e-boats, to launch vessels that don’t pollute.

“We are the first [resort] to launch e-boats, and we sincerely hope the others will follow,” MahaRaja’s founder Mahasti Motazedi, a French former aeronautics engineer and Microsoft sales executive, tells Eco-Business.

With tourism growing rapidly Raja Ampat—although remote and expensive, visitor numbers have grown by 1,300 per cent in under a decade—the region’s reefs, the world’s most biodiverse, will hope she’s right.
