Diy Canoe Building Plans Meaning

A sailboat built out of luan plywood, fiberglass, epoxy, and a little mahogany. Mostly plywood. It's an outrigger canoe modeled roughly after a proa, but with a more western style hull shape and sail.

I think it took around person-hours to finish, although a boat with less finish work and slightly less laminated mahogany, could be finished in half that time. I should give a general outline of what sort of sailboat this is. A proa is a double-ended outrigger canoe. The sail is rigged up so that it can outrigger canoe plywood 00 fully forward of the mast, and the rudder can be moved. The boat never tacks, and instead just stalls and starts going backwards.

We didn't want to mess with the rudder for this sort of design, so we opted for a single ended outrigger canoe. This has the downside that one tack is different than the other, which in moderate winds is not especially troublesome.

The most interesting thing about this boat is probably the construction technique. We tried to make everything extremely easy to build, as outrigger canoe plywood 00 as tolerant of a lot plywoood slop, but still lightweight enough to carry single-handedly, and as strong as outriggrr necessary for a freestanding mast.

We compromised a small amount on hydrodynamics to do this as we have a sharp chine. The high aspect ratio of the outrihger makes this less of a compromise. The basic design is very simple; The main hull has a flat deck which forms the backbone on which the rest of the boat is built upside-down. The ribs, mast box, and centerboard box, are pywood to the bottom of the deck.

The sides and bottom of the boat are then glued to the ribs. To make the boat comfortable with a flat top, we put benches out over the water to sit on instead, which facilitates hiking as. And outrigger canoe plywood 00 rear transom, which is more of a glorified bulkhead. We then simply cut the top and bottom to outrigger canoe plywood 00 the angle and curve of the side panels.

To make sure everything would fit together simply, we only made planks bend along a single axis, and always in parabolic shapes this is roughly how a uniform stiffness beam wants to bend, at small angles. Since we wanted side planks that could be cut on a table saw, outrigger canoe plywood 00 only bent along their long axis, in a parabolic shape, this became the starting point of the boat. Simply define the boat length, the vertical slope of the side planks, and the maximum width of the boat, and the boat is fully outrigyer in terms of camber and planview.

All that remains to be determined is the vertical slope of the bottom planks on the hull. Just pick outrigger canoe plywood 00 pleasing to the eye here, unless you are interested in a particular ratio in the tradeoff between hull drag and static stability.

With the above chosen, the hull is fully designed. Now build! Now plug everything into any plotting program and figure out all your plywwood cross sections, taking into account the thickness of your planks. You'll probably need about a gallon and a half of epoxy, and a gallon of titebond 3 or comparable 'waterproof' woodglue this can be replaced with epoxy if desired, but is a lot healthier to work with, and sets up quicker.

Any wood-wood joint which is only going to encounter splashes, or which will be coated with a protective coat of paint in the end, can be glued in with a waterproof wood-glue. Make a table of all of your bulkhead dimensions. No, really, do it. Acnoe worth the time. Then cut out the deck, and glue on some blocks of wood to hold up the bulkheads, added in step 2. In the picture, the centerboard is sitting on top of the square pieces that will be used to join the bulkheads to the deck.

The bottom of the hull only takes a very diffuse load, while the plyood of the deck has to take point loads your feet. This means the top should be thicks, and thus that it makes a better spine on outrigger canoe plywood 00 to build a keel-less boat. Cut all of outrigger canoe plywood 00 planks and glue your bulkheads to the bottom of the deck.

It is helpful if you cut out any holes you need in the deck say, for the mast and centerboardbefore doing. Make very sure that the bulkheads are centered along the axis of the boat.

It wouldn't do to have a wobbly side on your boat. Also make sure that your bulkheads are cut and sanded to within about a millimeter of your design spec.

This comes in handy later in decreasing the amount of time you have to spend making oytrigger fit when they do not.

If you complete this step with great care, everything else will just fit. The mast box, the centerboard box, and backing plates for all deck hardware, need to be added before sealing off the bottom of the boat. It is easiest to do before the sides are glued on. If you plan to use stays, don't worry overly about the mast box.

Just make a pile of plywood cutouts in the shape of oitrigger mast. In our case, the mast was a free aluminum pole, originally intended for the awning on a mobile home. If you intend to have a freestanding mast, do the same thing, but make a lot of plywood cutouts, and be very sure that the whole thing is glued together tightly, and sealed off from water.

Plywoo mast box can fill up with water when the boat capsizes, so don't make it any larger than it needs to be. The centerboard box is less important, Figure a good slope for your centerboard and build it. Both the mast and centerboard boxes should be supported by extra-thick bulkheads on either end, and should have extra bracing holding them on to these bulkheads. The picture of mast and centerboard box shown here was taken before some more stiffening blocks were added.

There is an added support between centerboard box front bulkhead and the mast box rear bulkhead, to help convey torque from one to the other and spread out the rather considerable load of outrigger canoe plywood 00 mast box. The backings for all deck hardware should be made of hardwood. We used mahogany, because we had some scraps lying.

Also, canke outrigger canoe plywood 00 Pink foam works. Since your sides are I hope at a slight slope from being perfectly vertical, they introduce a slight camber into the shape of the boat.

This is outrigger canoe plywood 00 good thing. You should have that camber from your previous calculations. Just prop up the deck until outriger has the proper camber, and drop the sides on. Some slight adjustments might be necessary a couple millimeters.

Then clamp, glue, and apply fiberglass tape along the outrigger canoe plywood 00. As a butt joint between pieces of quarter inch ply isn't particularly outrigger canoe plywood 00, I highly recommend that you reinforce all joints by a piece of inch or inch and a half fiberglass tape. This can be harder to fit, as the shape of the bottom planks is a bit stranger than the others, and thus harder to cut accurately in that is asymmetric and all sides outrigger canoe plywood 00 curved.

In our outrigger canoe plywood 00, the pieces didn't quite fit, so we had to go through the hassle of filling the crack, and applying liberal amounts of fiberglass tape to the outside and inside of the crack.

Note that nothing should be fiberglassed to outrigger canoe plywood 00 outside of the boat before the final coat of fiberglass. This is outriigger in maintaining a sleek finish. Once you wrap the whole thing in glass or, say, the top half of the boat and then the outrigger canoe plywood 00 half of the boatcut out glass around holes in the boat as in the mast hole or the centerboard hole before the glass dries.

Feel free to tuck the excess glass down into the hole a little bit, for a cleaner look. Outrigger canoe plywood 00 you apply the layer of fiberglass, apply a finish layer of epoxy. If you've never done this outrigger canoe plywood 00 of fiberglassing here is outrigger canoe plywood 00 general process: 1: smear epoxy over the surface on which you wish to apply fiberglass.

I don't have any pictures during the process. We layed up the top of the boat and then the. The overlapping area should be a ring a couple of inches tall at the top of the sides. This is less conspicious, and is out of the outrigger canoe plywood 00. If you find a sail, then you are done with outrigge step.

If you outrigger canoe plywood 00 one, then it goes something like this: 1: buy oz dacron 2: figure out how much luff the extent to which the sail is not flat you want, and then figure out how to sew this into the sail. Oitrigger assumption that the sail is roughly a pyramid shape works well in figuring how to adjust your seams 3: use brass or stainless grommets. Spend enough money for good ones. The boat is held together with bicycle inner tube.

If tied tightly, these make good joint. The mast is put up, the sail rigged, and it's ready to sail. I originally thought my rudder was too outrigger canoe plywood 00. I was unfortunately wrong, and when I cut my rudder shorter, the boat became much less manageable.

Very nice. Never saw one built from the deck up. Make another outrigger for the other side,won't dump you in the water. Through bolts and wing nuts will hold them in position.

A water oufrigger hatch in each hull might also be useful, allows you to check for outrigger canoe plywood 00 and gives some storage for kit.

Great project, really unique sailboat I'd love to have a proa. I sail a Europe Class 11' 98lbs monohull, un-stayed rotating cat rigged with 75 sq ft. Just a thought, great job. By damonv Follow. More by the author:. Did you make this project? Share it with us!

DIY plywood canoe for fishing and roof racking. Create a paddle or sailing outrigger canoe from a fibreglass or wooden Canoe or Kayak. Even an elderly Grumman! Convert your old canoe into an awesome sailing machine or fishing or diving platform. April 12, at PM. Nov 19, �� Outrigger The beams or spars to the ama (outrigger float) are 50 mm x 50 mm knot-free timber about metres long. I cut a clear x 50 mm piece in half with the skill saw. The ama was a second-hand mm-diameter plastic sewer pipe, metres long, from a building site. I did saturate it with bleach before using it as a waka float.
