Field notes
The homepage lays out a reference-to-recall workflow: search a rule, follow related explanations and source references, then practise recognition and oral answers. Its examples include COLREG Rule 19 and Rule 35, while the planned study passes extend to buoyage, watchkeeping, ECDIS, GMDSS, and India OOW preparation. Offline use is described as covering the opened free library and study preview; purchasing or restoring a pass still requires connectivity.
