Yieh Boats

Run by the sun.Built in Kenya.

Yieh Boats designs and builds low-cost passenger and cargo boats for African lakes. Their only propulsion energy is the sun.

What we doDesigned around your route

We provide sustainable water transport solutions.

  1. Your requirements

    Based on your requirements we design the required boat for you.

  2. How you operate

    We look at how you want to operate your boat.

  3. The design

    We find a design that is low in operational cost and maintenance.

The prototypeTested in Kisumu, Kenya

Two traditional hulls, built by local boat builders.

Made mostly from locally sourced materials.

Where it worksSolar output, 1994–2018

The concept holds wherever the sun gives more than 4 kWh per kWp a day. That is most of Africa.

What does it look like on a bigger scale?

Passenger transport

Speed matters most, so the boat needs a bigger motor and larger batteries. The propulsion energy comes from an on-shore solar charging station, where batteries are swapped. Panels on board add 10–20% of the energy.

On-shore solar charging stationPanels on board
10–20%
Capital investment: higher

Batteries, a solar charging station and the boat motor.

Cargo transport

Speed matters less. For a slow boat, solar can provide all of the propulsion power.

Panels on board100%
Capital investment: lower

A smaller battery and motor, and no solar charging stations.

Why it paysCompetitive advantage

In water transport, fuel is 40–60% of operating costs. Our boats use none.

  • Safe operations

    A safe vessel design and a competent crew.

  • Lower maintenance

    A simple propulsion system costs less to keep running.

  • A resilient system

    It depends on energy generated locally.

For the lake, and the people on it

The system runs without greenhouse gas emissions and does not pollute the lake that millions of people depend on for their livelihoods. It is cheap transport that benefits the people who live there.

The boats are built in Kenya, by Kenyans, mostly from Kenyan materials, creating quality jobs. Lower transport costs and less pollution open up new economic opportunities.

ImpactUN Sustainable Development Goals

Goals we are building toward.

The 17 UN Sustainable Development Goals: 1 No poverty, 2 Zero hunger, 3 Good health and well-being, 4 Quality education, 5 Gender equality, 6 Clean water and sanitation, 7 Affordable and clean energy, 8 Decent work and economic growth, 9 Industry, innovation and infrastructure, 10 Reduced inequalities, 11 Sustainable cities and communities, 12 Responsible consumption and production, 13 Climate action, 14 Life below water, 15 Life on land, 16 Peace, justice and strong institutions, 17 Partnerships for the goals.

Our transport system ensures that the African lakes are not polluted by emissions and oil spills, caring for the life below water 14 and the life on land 15 at the same time. Ensuring that the millions of people living around the lake, and whose livelihoods depend on a healthy lake, can have access to clean water 6, and they can fish on the lake. And in turn fishermen have decent work 8 that is sustainable making sure there is no hunger 2 and poverty is reduced 1. With reduced pollution people around the lake will live with good-health and well-being 3. Creating a truly sustainable community of people 11 living around the lake, where inequalities are reduced 10 and peace and justice thrives 16. The transport system does not require fossil fuel and ensures access to affordable and clean energy 7 used for transport. Our transport system can be rolled out all over Africa where the conditions are right. Creating a new industry that is innovative and forms part of a new transportation infrastructure 9. To build our boats we are going to use quality education 4 to create the best boat builders, captains and maintenance crew. We will educate women and men ensuring gender equality 5. Our people will have decent jobs 8 with climate action 13 and responsible production 12 at its core. To make these bold plans a reality we need to form partnerships 17 with communities, governments, NGO's, companies, etc.
