Technical Specifications
Overview
Alexander von Humboldt is a German sailing ship originally built in 1906 by the German shipyard AG Weser at Bremen as the lightship Reserve Sonderburg. She was operated throughout the North and Baltic Seas until being retired in 1986. Subsequently, she was converted into a three masted barque by the German shipyard Motorwerke Bremerhaven and was re-launched in 1988 as Alexander von Humboldt. In 2011 the ship was taken off sail-training and sent to the Caribbean for the charter business, then she was converted to a botel.
Composite Risk
Multiple adverse factors, or a hard ship-specific signal, lift this hull above the fleet norm.
A coverage-weighted blend of the single component we could read for this hull; the weights renormalise over only the components present, so a thin read is never inflated and a hull is never credited a “safe 0” for a signal it has no row for. This headline is flagged low-confidence (a thin or structural-only read) and should not be treated as a verdict. Higher means riskier. Derived in-house from government-open port-State-control, flag, sanctions and our own vessel data; weight it by the coverage above.
Commercial
Price it in the Route Planner between any two commercial ports: ballast and laden legs, two fuels at live bunker prices, port and canal costs, the weather on the way, and the TCE set against the market.
