DIY wooden canoe - which construction method?

Building a wooden canoe yourself is a big but also very fulfilling project. Depending on how much skill, time and equipment you have available, different construction methods come into consideration for you. You want to build a wooden canoe yourself and you are still unsure which construction method you want to use? Maybe you will find an answer in our comparison of construction methods:

Strip construction

The most challenging construction method is probably the strip construction method, in which concave and convex milled wooden strips are glued together on molds to create a thin wooden hull. This can be done easily and quickly with staples or, much more laborious but also more beautiful, without staples. Basically any type of wood is suitable for making the strips, since the wood plays more of a form-giving role due to the subsequent sealing with fiberglass and epoxy. The wood properties are of secondary importance here. Just make sure that the wood can be processed well and is not too heavy. It is not without reason that the wood of Thuja plicata, known as red cedar, is the most common used wood in this construction method. It is very light, homogeneous, easy to work with, extremely durable and, by the way, smells very good. To make the strips you need a table saw and a router table on which you can work the 6mm thick strips with a cancave and convex routerbit. Depending on the width of the boat, you will need about 80-100 strips, preferably in full length. If the strips are too short, you can also install them butt to butt. Next, you need a strongback on which you can place the molds. The strongback should be as stable and straight as possible. On it, you set up the molds, which you saw out yourself according to a construction plan. Take your time to align the molds so that your canoe will be symmetrical later. Start the planking from the gunnels and work upwards towards the keel. The first strips are easy to attach, but in the end you have to fill the hole at the keel, where somewhat more demanding adjustment work is required. This is followed by sanding the outer hull and finally applying the fiberglass reinforced epoxy. This is an art in itself and does not have to be done perfectly on the first boat. What is important is a suitable temperature, a matching system of glass fabric and resin, concentrated and speedy work, and good protection against the hazardous chemicals of the resin. After laminating the outer hull, the semi-finished wooden canoe is lifted from the molds and sanded from the inside. This is followed by laminating the inner hull, which is much more challenging than the outside simply because of the shape. After both sides are laminated, the cured epoxy is finely sanded to prepare it for later varnishing. Before this is applied, however, the inner and outer gunwales, seats, yoke and decks still have to be installed. We could write several blog articles about these parts alone, so you can see that it's not all that easy to build a wooden canoe yourself. If you have some skills and read the many good books about canoe building, you will certainly be able to realize the project!

Stitch-and-Glue

Stitch-and-glue construction is similar to strip construction, but instead of narrow wooden strips, the hull is built from plywood planks. These are sawn out according to a construction plan and, following their special shape, result in the hull shape of the canoe. The planks of 5mm thick plywood are first "stitched" with wire and then glued with epoxy, sanded and finally laminated with fibreglass and epoxy. The stitch-and-glue construction method inevitably results in a hard or multichined hull, which are hull shapes with edges. Who does not like this is better advised with the strip construction method, otherwise the stitch-and-glue construction method is our tip for you if you have little time but still want to build a canoe yourself.

 

Skin-on-Frame / Fuselage-Frame

Our favorite construction method is the skin-on-frame method, which can be realized in the traditional way with steam-bent ribs or in the modern, fuselage-frame construction. In traditional construction, a wooden frame is built up from gunwales, steam-bent ribs (the transverse frames) and stringers (longitudinal frames), which are knotted together with artificial sinew. In the fuselage frame construction method, the steam-bent ribs are replaced by components made of plywood, which is less time-consuming and does not require a steam chamber. The wooden frame, which gives the canoe its shape, is then conscientiously oiled and then covered with fabric and painted. Polyamide (nylon), polyester or even cotton are suitable for covering. The varnish makes the fabric waterproof and the wooden frame finally becomes a canoe. This construction method is recommended if you want to build a very light and yet robust canoe yourself. The materials used are more user-friendly than the strip construction method. Also, the SOF construction method requires less diligence work, such as days of sanding. Should you decide to use the traditional SOF construction method, you can look forward to steam bending, which is really the highlight of craftsmanship in skin-on-frame canoe construction!
The delicate-looking wooden frame and transparent exterior, through which the sun shines and shows the frame and the canoeists' legs as shadows, often lead to the conclusion that SOF canoes are not very robust. That they are, however, has been shown to us by many encounters with rocks and branches, so we would recommend skin-on-frame canoes for rivers as well!

Comparison of the construction methods

In addition to the demands on your craftsmanship, the choice of design and the purpose of the canoe, as well as the material, the price also plays a role, of course. The strip construction method is significantly more expensive than the other construction methods. If you want to use red cedar and ash you should calculate about 1000-1200€ for the complete material for a self-built strip canoe. The stitch-and-glue construction method is a bit cheaper here and certainly attractive for many because of the less time required. The skin-on-frame construction method is the cheapest to build. Here you should manage to build a canoe for 500-600€ if you use Red Cedar and ash. In terms of time, which of course depends on your skills and experience, you will need to spend the most time for the strip construction method, and the least for the skin-on-frame method. Considering ecological aspects, the skin-on-frame construction method has clear advantages. The wooden construction is treated exclusively with natural oils - Only the artificial sinew used to knot the frame and the varnished skin are made of plastic, although here too you can choose alternatives made of cotton and natural-based varnishes.

 

Can't decide yet?

No matter which construction you choose, in the end you can paddle in your self-made canoe and the feeling is simply amazing! We hope that we could help you with this article in choosing the construction method for your wooden canoe and wish you a lot of fun building it yourself!
