Relitto Asia (Civitavecchia)

Open offshore wreck on sand off the northern Lazio coast, with the Italian mainland blocking the eastern sectors (E-NE) and the full Tyrrhenian fetch open to the south and west. The dominant wave exposure is the Libeccio (SW) and the long-fetch Scirocco (S-SE), with the Mistral/Tramontana (NW) also reaching the site across the Tyrrhenian; being microtidal, conditions are wind-wave driven rather than swell driven. Boats only run when the SW-to-S sectors are calm, so the wreck is a fair-weather dive despite its depth.
