From the eco-friendly mango collection, this small elongated oval serving dish is perfect for serving up whole loaves of bread or muffins and pastries at a buffet.
I was working on a design for a short (slightly less than 8 feet long) small, flat-panel, hard-chine canoe the other day when I clicked the wrong button in my design software. Naturally it must be molded instead of using flat panel construction, but after I saw it I decided to see how much weight it might be able to carry.
My concept here is to come up with the 'shortest canoe in the world' -- one that actually looks like a canoe and hopefully behaves like one too. This little canoe will fit inside a compact car with the front passenger seat reclined, which makes it ideal for an individual who just wants to throw it in the car and go for a paddle on a moment's notice.
It may not track well with a single paddle unless the paddler uses a correcting stroke, so a double paddle may be more satisfying.
You might try flattening the sheer line somewhat, amidships, and moving it's curves toward the ends a bit. Another note -- if the gunnels are that far apart and that high, it's hard to use a double paddle properly. I've found some really short kayaks online but no canoes this short -- none with the type of planning and design work I'm putting into this one anyways.
Thanks Todd, maybe you're right, I will play around with the profile a bit more, and then post the new images later. A keel isn't going to make much difference on a boat that short and that deep in the water and it adds drag.
Do you have an example or a description you can post so I have a better idea of the type of stem profile you're referring to?
If the gunnels are that far apart and that high, it's hard to use a double paddle properly. An earlier version had so much tumblehome that I took it out because it was beginning to look rather strange -- not from the side but from the front and rear -- but maybe you're right so I'll try more tumblehome again later and post new pics at that time. A stem profile like the nice rounded traditional-looking one that you have drawn looks very canoe-ish, but really doesn't do much to make the boat track.
The same basic thing can also be done with a curved stem profile if you don't like straight stems. The design can make up for tracking problems due to bad paddling technique to some extent, but if you have this problem, you should fix it as it's a lot easier than trying to design your way out of it.
Since you are so limited in available waterline length and since you can't throw out much, if any, hull volume without turning it into a submarine, speed and tracking are going to suffer and I doubt there is much you can do about it. I seriously wonder whether the boat would perform better fattened up to about 35" wide to decrease its draft and to allow you to kneel for more power and reach, in order to move it forward and make it track using technique.
I used to do some fun consulting almost every year for the University Engineering students when it came time for the concrete canoe competitions. Right, that's why I'm considering other options, one of which is being discussed in the above-mentioned thread -- a slot that holds a removable aft-mounted skeg which remains under water and does not spoil the boat's 'canoe-like' profile but that nevertheless makes the boat easier to paddle in a straight line.
If the intended use is slow traveling, poking around and gunkholing without a time schedule, then go for it.
This is precisely the concept -- a tiny little boat that looks like a canoe but that is as small and light as possible, and handles as safely and predictably as possible given its obvious limitations.
It's hard to say that your boat tracks well if it stops dead 2' after you finish a stroke because it's so short and stubby.
It probably cannot, but my most recent version has a v-bottom now since I already figured that it might help a little. Tiernan adds that the reason most boats for sale today are made of fiberglass is that they can be made by semiskilled and unskilled workers who are cheaper to hire than the skilled craftspeople needed to build a wooden boat. Another is that when we build in wood or commission others to do so, we are helping to maintain an important tradition.
I wonder also whether the argument that building from wood is environmentally friendly has really been made. PS Fans of the US designer John Atkin will be interested to know that Tiernan is currently weblogging the build of a clinker-built Atkin Ninigret. PPS I’d draw your attention to some of the comments below, particularly those of West Country boat designer, occasional building and general sailing man John Hesp. Gavin, most of Tiernan's list deals with the engineering advantages of wood, as if we bought boats based on these facts.
Trees have been growing, falling over, rotting, releasing CO2 into the atmosphere for years and it hasn't caused a massive increase in atmospheric CO2. I do see what you mean – it seems unreasonable to reduce these issues to numbers and engineering criteria when one of the key reasons we go boating is often to get away from such prosaic considerations. Nevertheless, these issues are worth considering as I'm sure your inner designer will concede, and the environmental questions are much more subtle than most of us thought at the beginning.
And of course, carbon emissions are tightly connected to economic activity and human activity in general.
On the other side of the issue, some fraction of whatever carbon there is in a plastic boat will remain locked in the material for a very long time. You don't think you've been led down the garden path by what sounds a rather journalistic BBC article?


Ironing and washing, to be fair – both need more heat where cotton shirts are concerned. One interesting little tidbit I read recently is that the meat industry in one way or another, contributes significantly more to global warming than transportation, worldwide.
One other nice thing about wooden boats, which has already been touched on a bit, but a nice one is gives pleasure to people, even when they aren't normally interested in boats. If the global warming cost of fossil fuels is added to that fuel we find ourselves playing a very different game. Did you know that one barrel of oil contains the same amount of energy as 12 men working for one year?

Our Faversham-based friend Alan Thorne can help with boatbuilding projects - constructing to plans in very tidy stitch-and-glue or more traditional techniques. Location: Vermont Square-back Canoe Plans I am looking for plans to build a small square-back canoe. Location: Lakeland Fl USA You have a set of wants and circumstances unique to your own situation. Location: La Florida In the early 1970's I built a small 2 hull boat which I used to tie onto the roof of my car.
But widen the square-sterned canoe until it's the width of a dinghy and it's closer to a dinghy than a canoe. Okay, you could keep it narrow, say 28", and limit the occupancy to one (maybe a small dog too), and cut 2 ft of the stern of a ten footer and yes, you have a very small square-sterned canoe.
Location: La Florida pistnbroke-You reminded me of what my friend did back in 1971. When making potentially dangerous or financial decisions, always employ and consult appropriate professionals. To support the canoe during construction, I’m building some trestle tables and torsion boxes. At first I was a little disappointed with the plans and supporting documentation as they assume that you already have a reasonable understanding of boatbuilding terminology and techniques, which I don’t. Since I am new to boatbuilding, it’s quite likely that I will make mistakes and not find the optimal solutions the first time.

It gives it a little more interesting and less box-like profile (same stem height and midlle depth, just a different curve). If you want to increase tracking and lower windage, do it with the underwater portions of the stem profiles, it's much more efficient. You can't see it because it's under water in the photo, but the stern has a slightly more exaggerated shape at that lower trailing corner on this one, too. Eight-foot boats that ride four or five inches deep don't glide worth a damn, no matter how much you want them to or how much design work you do. V-bottomed canoe hulls do track a little better than arched bottoms and at decent cruising speed the V can also add a little stability if you believe the folks at Mad River Canoe. Boatbuilders teach each other, and the skills have long been conveyed by oral transmission. But if we only build boats out of oil, and keep a constant number of trees, there will be a nett increase in CO2. I became aware of this when a BBC magazine looked at the issue and decided that the heat consumed in ironing a cotton shirt meant that poly-cotton shirts were a better environmental deal; so it seems to me that we should consider all the inputs and outputs, not just the obvious ones. Gaseous hydrocarbons are often very powerful greenhouse gases, and if a boat needs eight coats of varnish every two years, what's the impact of that?
I wish someone would give me some nice, clear well worked answers that left me knowing where I was on all this, and that I could quote when the issue arises.
I can guarantee that the energy expended per year ironing my cotton shirts is less than it takes to make a years worth of polyester shirts….
And it seems to me that I've never even owned an iron that got hot enough to iron a cotton shirt properly!
We should use wood because we want to, and save our agonizing about our carbon footprints for the times when it really counts.
I am not about to give up my roast lamb, but cutting my meat intake in half would do me good, and probably make a more significant dent in my carbon footprint than all the other little fiddles one reads about put together. The difference in the reaction of people when I am paddling some rental day-glo plastic fantastic canoe, and when they see me in my little varnished oak and pine S-O-F canoe is remarkable.


I seem to remember writing about the issue years ago, and finding that the energy savings from triple glazing can take a century to pay back the investment. What's needed is some sort of mechanism where the cost of dealing with CO2 problems are paid for by the sources of CO2, then triple glazing and the like would look a lot more attractive finacially.
If person A manufactures a triple glazed panel using oil based energy sources the cost of energy is very low but the CO2 generated is very high. The cost of the triple glazed panel goes up slightly because of the embodied energy, but the cost of the energy being saved over, say, 20 years is a very worthwhile saving. Theres a tigermoth biplane at our local airport that is probably 60-70 years old with wooden wing spars that DO flex.

The idea for this came from an article on The Simple Woodworker (thanks to Paul for the tip). With any luck someone out there will read this and make some constructive comments before it’s too late.
The Mango tree bears fruit for about 40 years, at which time it is cut down by the farmer to make room for new seedlings. Much of it is obviously due to length, but those little corners hanging down at the bottom of the stems do wonders for tracking, especially the one at the stern.
You are simply trying to push too much water out of the way with a blunt instrument for the boat to glide nicely.
The question here might be whether that little 8' boat, riding that deep in the water can get up enough speed to notice a difference and I'm not sure it will. With our busy working and family lives I have no hesitation in saying that we own and use at least one boat that we wouldn’t be able to keep up it on a DIY basis if it was made from wood. For example, when wood eventually rots its breakdown must release carbon dioxide and the much worse global warming gas methane.
If the returns are so small, I'd suggest there are likely to be other areas we could cut down on that would make more of a difference. If person B manufactures the same panel using energy from photovoltaics the cost of energy is very high, but the CO2 released is very low. He took 2 pieces of corrugated metal roofing, doubled them over and screwed a short piece of 2x4 into each end. In fact, it is because the instructions are quite difficult for novice boat builders to understand that I felt it was worth documenting my building process as it might help others who want to build one of these. The Mango wood is then reclaimed by local craftsmen and carved into a wide variety of beautiful shapes.
This is simply not going to change, and paddling any distance in such a boat is far more tedious than trying to do it in a decent normal-sized canoe. If not, it's a good thing to work on and a far better idea than trying to figure out how big of a fin you would need to add to one to force it to track. Then they would proceed to make a copy out of concrete that weighed 500-600 pounds and couldn't figure out why they were so slow and tippy? So what is the lifetime cost of a wooden boat to the environment compared with a plastic one? With regard to the maintenance I was referring to epoxy encapsulated wood like the Ninigret I'm building. The recession might have lowered energy costs, but I can see us coming out of it with soaring energy costs. I was inspired to build one of these beautiful canoes after a friend showed me these two examples: Libby Small Craft and Grapeview Point Boat Works. Example: every single marathon racing boat (the best tracking open canoes) none of which have keels. Maybe plastic boat owners are more inclined to motor than sail, and maybe plastic boat owners are more attracted to resource hogging marinas? Sure, we need a reasonably big car to haul the family around, but could we get away with an overgrown go-cart for the commute to work?
On a boat where you can pretty much reach both ends during a typical paddle stroke if needed, the bulk of your tracking should be a product of technique. Just to add a factor that seems relevant, what is the contribution to global warming made by the drying of spirit-based paints and varnish? It fell apart when our friend stepped on the cross beam, breaking it which caused the boat to fold upon itself like an open faced sandwich. He had a good time upon the river after he corrected that design flaw and I built mine the following weekend.
