you can always make a high ratio ....

...... scarph joint with the type of wood you really prefer .
By high ratio I mean in the order of 1 to 12 or greater . Fast , accurate and easy once you make the simple hand sawing jig up .
For best strength use a slow cure epoxy and do not immediately clamp up after 1st coat , but rather recoat a 2nd time before clamping . This aids greatly in avoiding a glue starved joint due to the end grains soaking in some dry spots (1st coat is allowed to soak in some , but must 2nd recoat before intial set begins .
It is also possible to have the center of the scarph right where you want to have one of fastners go through (just extra security) .
Last but not least allow several days , even 5 or more for the epoxy to fully cure befor unclamping and arching the joint onto the canoe .
