A note on paper charts
The plotter is better at everything except giving you the whole picture at once. I keep the paper folded to the current passage on the chart table, and I have never regretted it.
Rewiring the masthead light
Every job on a boat takes three trips: one to find the fault, one to discover the part you need, and one to do the work. I have stopped fighting this and now plan for it.
Anchor watch, honestly
The alarm app is useful and I still wake at three to look at the shore lights. After a dragging incident in soft mud I do not think this will change.
