Het Starteiland — officially known as Kolmeersland — is an island on the Sneekermeer, near Sneek, accessible from the mainland by ferry.

The roll-on/roll-off pont called "de Sweagen," introduced in 2019, connects the island to the shore and can accommodate boats on trailers, campers, and small trucks.

A smaller passenger ferry, "de Kolmeersland," carries up to 12 people, including wheelchair users. Havens Zuid is one of three harbors on the island, which together offer more than 400 berths with a maximum draught of approximately 1. 90 meters.

Deep-draught yachts are best directed to the southern harbor via the Kolmeersgat. The harbors are equipped with electrical supply posts, drinking water points, and a pump-out installation for waste water in the southern harbor.
