Martin is not starting this from the position of an accomplished ocean sailor. The project begins earlier: with the work of learning the boat, the weather, the systems, the repairs, and the decisions that matter offshore.
Before a single-handed circumnavigation is realistic, there are skills to build, miles to sail, confidence to earn, and offshore experience to gain. Later, there will also be the right boat, a serious refit, and the preparation to make the attempt responsibly.
The point is to document that process honestly while it is still uncertain, practical, and unfinished.
