The snippets describe WSV Helius, a sailing club and marina in Hellevoetsluis, but do not contain specific information about an access point called "Helius Haven" as a distinct POI.

However, the Heliushaven itself is clearly described as a harbor area, and the access point likely refers to the broader marina/harbor location.

Helius Haven is situated along the Heliushaven in Hellevoetsluis, Zuid-Holland, with a direct connection to the Haringvliet.

Through the lock in the Haringvlietdam, the Haringvliet provides onward access to the Noordzee, making this a well-positioned entry point for coastal and inland waterway navigation.

The harbor lies on a quiet, dead-end road just outside the historic fortified town center. The Heliushaven hosts multiple marinas, including the member-based WSV Helius and the commercial Marina Cape Helius.

A trailer ramp is available at Courtine 33, with depths ranging from NAP -4. 30 m to NAP -1. 90 m; users are required to report to the harbormaster before launching.
