The idea of using solar and human power to drive vehicles is nothing new but each new design that applies these principles is at least a step in the right direction – away from fossil fuels.
Perhaps the best part about these designs is that they push the boundaries of current thinking and appropriate green technologies for seemingly everyday uses.
I am not sure how practical this designs are, I mean – is the solar power is ebough to run the boat? Don't forget you would charge it up before you went out as well so you could get most of your traveling done without sun or pedals.

I'm getting close on the funds to build, but where the hell do I put the damn think, and how much is that going to cost me? Once again its horses for courses, I'm not sure this course would run a cat as effectively as a mono.
Boston Previous Member   one cat I really liked because it was so modular looking was this one.
It would be fun to kinda work out a construction plan that I could do to end up with this thing. Boston Previous Member   that particular cat I'd just use as a weekender, once again I'm just daydreaming away the holidays. Like I said my truck project is just about done and I'm stupid to get started on my next project. Originally Posted by michael pierzga If youre considering charter you must build to the market.
I lived in SE AK for some years and saw a lot of Liveaboards in all the harbors down there. Anything left in the water or up on deck suffers, as it rains salt water and Salty Fog's sit on us for sometimes days. Other than that your roving living room is handsome and looks like a lot of Liveaboards up there. Oh and I know no one will like this next idea but its just an exploratory so I can do whatever, its not like if it doesn't work I don't have this here eraser all ready to rock and roll. I just put in a bid on a warp9 motor ($100 lets see if I get it, they go for ~$3500 new ) 72V 335A ~34hp and might consider a diesel hybrid system using wind, solar or tide to help charge the battery bank. From a draft point of view I get the same displacement but with a slightly shallower draft. Also for a vehicle only doing 8~10 knots I'm not sure a rounded form is really all that much more efficient than a Bolger style hull would be. CatBuilder Previous Member   I'd say you're starting to close in on it nicely, Boston.
When making potentially dangerous or financial decisions, always employ and consult appropriate professionals.
Possible materials - polystyrene, plastic tubing, plastic bottle, balsa wood, rubber balloon, empty aluminium drinks can; consider anything that is low weight and floats well. Do you connect the prop shaft directly to the motor shaft [a 1:1 ratio], or use a reduction gear to provide greater torque (turning force)? Your boat could have larger slower running propeller giving larger masses of water a lower acceleration, or a smaller faster running propeller giving smaller masses of water a higher acceleration. These technological innovations don’t come bundled in a blunt and unimaginative shell, though.

Grove Boats is based in Switzerland on lake Geneva and is dedicated to building solar powered boats. As with car races, techniques developed at the highest levels of the sport, will eventually find there way to recreational users.
Nagasaki, Japan - April 28, 2012: A man and young boy sail a small solar powered boat on a calm waterway at Nagasaki waterfront. One could envision a small fleet of these replacing rent-a-boats at various tourist destinations around the world.
The solar and pedal option just extends the range to as far as your feet and the sun will let you!

I was thinking of doing a gasification system for the house but now I've got this new wood stove and it seems like no one else around here ever heard of collecting wood out of the alleys for fuel. Not sure it would work out at all cause its so heavy a system but its always fun to see if I can jam something like that in.
Looks very protected, I gotta check the depth but there's a piece of land for sale with a long slopping short right next to what looks like a great mooring site. If you are using two cells to power one motor then connect the positive terminal of one cell to the negative terminal of the other. Since sailing has always been the most eco-friendly way to cruise the seas, this project suggests the creation of a third category of boating that bears characteristics found in both sailing and motorboats.
The first option offers a 30Nm of autonomy at a 5 kn cruising speed, while a combination of electric and diesel propulsion can achieve a 487Nm autonomy at 9 kn, by consuming only 400 liters of fuel.
The yacht’s captivating lines and broad spaces, both externally and internally, create an aggressive profile, without giving up on space comfort.
We have crewed charter boats in the favourite yachting hotspots in the Mediterranean and Caribbean as well as worldwide locations.
Their design is relatively traditional, especially compared to some of the other solar boats described here. Their boats can be found all around the world, of course mostly in sunny places to take full advantage of the build-in solar panels.
A small little pontoon style boat, powered by the sun.This little boat was built in Canada of under $3000, which in itself is already impressive. The TU Delft Solar Boat Team is very successful in the Dong Solar Challenge, they are already working on a new boat for the 2016 challenge.
All around the globe interesting initiatives are coming up, but the costs of designing a boat powered by electricity are substantial. Children were allowed to steer the prototype boat which was being demonstrated at the 2012 Nagasaki Tall Ships Festival.
Still, you get to toss out the pricey gas costs associated with most water cruisers and relax in the sun when the weather is nice and pedal your way to shore when it isn’t.
Sufficient power storage is a must so that pedaling is kept to a minimum and done only in emergencies. But its kinda hard to know what parts I need when I'm still up in the air about what to build.
Molds and epoxies just aren't my realm of expertise but it would be a fun little thought project to figure out how it could be done. I could build it out of ply I think, not sure if its worth trying to keep it solar or not if I did.
20K, if I want it, heavily forested, no utilities or even a prayer of utilities any time soon. Given the trade offs I think I'm safer with a thicker shallower hull that weighs about the same.


This catamaran design project’s goal was to create a boat capable of being autonomous and self-sufficient from an energy standpoint. This decision allowed for less resistance in the water and therefore less propulsion energy. Services onboard are comprised of A+ Energy Efficiency class equipment and LED illumination.
Some are designed for recreational purposes while others are build to break records, some are build by professionals and yet others are build by enthusiast. The boat is fully powered by electricity and can be charged by either the sun or connecting her to shore power.
Al though the post is already about two years old, not much news can be found about this boat or whether it is successfully being sold.
As you can see, the boat cannot be used for recreational purposes, but it is a very cool boat! And again, this boat is not for recreational purposes, she was build to sail around the world on only solar power. Another major obstacle is range you can squeeze out of the batteries, for many people this is still way too limited to replace traditional propulsion techniques.
I really like that one I lofted earlier in the year before I found myself stuck rebuilding the truck. So I have to be able to afford x period of time before I can hope to even begin recouping costs. Someone proved me way wrong about the cost of the solar panels, which I was happy to accept. I can make one ~90° degree joint very strong using about the same or less wood than I'd use in a 45° joint and I can better protect that end grain and with a better rabbit on a 90° than on a 45°. The low percentage can be explained by numerous factors, not least of which is the need for a very specific instruction in order to sail. The boat is designed to be constructed using the most advanced technologies in the field today; vacuum infusion epoxy resins and Kevlar laminates where employed to achieve a lightweight yet inexpensive hull. This is ferry is commercially exploited in the harbour area of Hamburg to take short day trips. Hell I'd build a rolling dolly with a nice winch and roll out whenever I wanted to park and forget the mooring. Its easier, its faster, and my chances if I do have a strike of damaging the chine are less, if I have less chines. The same lightweight approach was employed for the superstructure by using modern materials that conform to EU regulations.
Unfortunately the pictures are too small to add here, so have a look at the website yourself. The multihull also allows for more space above deck; this provides an area of 35 sq m (380 sq f) of photovoltaic panels, supplying the vessel with enough energy to become self-sufficient.
On a warm and sunny day it would be great to take trips on this boat, but there is no protection against wind or cold weather, which can be a problem on the water. Reasonably efficient, and I could have hidden the simplicity with some stylish design, which I failed utterly to achieve with my rather pathetic attempts.
