# Pedal-Propelled Enclosed Kayaks The WiTHiN Human-Powered Boat is Fueled by Feet By Sarah Moore | Published 2012-06-02 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/within-human-powered-boat References: [gizmag](http://www.gizmag.com/within-human-powered-boat-for-sale/22750/) & [adventuresofgreg](http://adventuresofgreg.com/blog/2010/11/11/within-is-for-sale/) If you feel like reducing your carbon footprint and want to instead increase the use of your literal footprint, you'll want to take the WiTHiN [human-powered boat](https://www.trendhunter.com/trends/foil-scoot) out for a spin the next time you are on the open seas. Created by Greg Kolodziejzyk, the vessel is fueled solely by the [spinning of pedals](https://www.trendhunter.com/trends/martoni-cardio-speeder) located inside the cockpit. The body of the boat is made primarily from [carbon fiber](https://www.trendhunter.com/trends/seanxt-elite), making it extremely lightweight and easy to move without a traditional motor. It has been reported to get up to a speed of 3.7 knots, but of course this would depend on how fast you want to pump your legs. Forget spinning class -- taking this ship out for a sailing trip will give you more than enough exercise for the day. ## Trend Insights (Trend Hunter) - Score: 4.6/10 - Popularity: 75% | Activity: 54% | Freshness: 8% - Audience gender: 70% men, 30% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) > [Transportation](https://www.trendhunter.com/transportation) ## Key Themes ### Key Themes Behind This Trend - **Eco-friendly Watercrafts:** Pedal-powered watercrafts like the WiTHiN human-powered boat demonstrate a trend towards environmentally sustainable water transport. - **Human-powered Transportation:** The WiTHiN boat shows a trend towards human-powered transportation in the form of pedal-propelled vehicles. - **Lightweight Carbon Fiber Structures:** As seen in the construction of the WiTHiN boat, there is a trend towards lightweight carbon fiber structures in watercraft design. ### Where This Applies - **Boating and Water Sports:** The boating and water sports industry can take advantage of the trend towards environmentally sustainable watercraft by creating new lines of pedal-powered vessels. - **Fitness and Health:** The fitness and health industry can leverage the trend towards human-powered transportation by marketing pedal-powered watercrafts as a fun and exciting way to exercise. - **Engineering and Materials Science:** The engineering and materials science industry can capitalize on the trend towards lightweight carbon fiber structures by developing new technologies and methods for creating high-strength, lightweight structures. ## Related on Trend Hunter - [Electric Bike-Like Watercraft](https://www.trendhunter.com/trends/envo-hydra-waterbike.md) - [Rowing-Style Recumbent Bikes](https://www.trendhunter.com/trends/varibike-extreme.md) - [Balanced Hydrofoil Watercraft](https://www.trendhunter.com/trends/neocean-overboat-100f.md) - [Hydrofoiling Electric Boats](https://www.trendhunter.com/trends/hydrofoiling-electric-boats.md) - [Propellerless Boat Motors](https://www.trendhunter.com/trends/boat-motor.md) - [Three-in-One Aquatic Vessels](https://www.trendhunter.com/trends/decathlon-x-outercraft-hydrobike.md) - [Pedal-Assist Electric Water Bikes](https://www.trendhunter.com/trends/otter-bike-explorer.md) - [Solar Panel-Covered Boat Concepts](https://www.trendhunter.com/trends/ms-porrima-concept-boat.md) - [Sleek Electricity-Storing Velomobiles](https://www.trendhunter.com/trends/electricity-storing-velomobile.md)
