Koper appears in the supply plan both near the start of the cruise and for the final northbound stage. A fuel call is not the opposite of sailing: it keeps HERA able to deal with calm, harbour manoeuvres and a changed schedule.
The reserve is calculated before departure
Engine hours, HERA’s experienced working range and a plausible consumption estimate form the expected need. A margin covers waiting, detours and longer motoring. The fuel gauge is compared with those figures and the hours already run rather than treated as the only answer.
The fuel berth is part of navigation
Opening times, access, commercial traffic and room for a 50-foot yacht are considered in advance. Fenders, lines and roles are ready, while the reserve must still permit a safe alternative.
Fuel planning creates options
Fuel planning is not about filling the tank as often as possible. It asks where engine reserve may be needed: calm weather, harbour manoeuvres, detours or a changed approach. Consumption, remaining quantity, reserve, access to the fuel berth and waiting time are considered before the last useful stop. Koper fits HERA’s route north and keeps supply from becoming urgent when alternatives are already limited.
A fuel stop is planned backwards from the next reliable supply point. Expected engine hours, current stock and a reserve for calm weather or a changed plan define the need before opening time and approach enter the day. The tank gauge is one input; consumption and remaining range are understood through experience with HERA rather than one display alone.
Frequently asked questions
Why does a sailing yacht need diesel?
For harbour manoeuvres, calm conditions, onboard energy depending on the system, and safe timing under changing conditions.
Why did Koper matter twice?
On different stages it offered a suitable fuel option close to the route.
