I have been following this series and one thing I find lacking is an awareness that, once split into thin strips, bamboo can be used as a coarse cordage once it is boiled enough. This can be used to eke out the available cordage for some parts, such as the ends of standing rigging. A bamboo shroud split at the ends can have strips cut into it, as wedged splices.
I also question John's statement that oars would not work well. If considered as sweeps, there is no practical limit to their length.
