Rivers and Powerlines

Rivers and Powerlines

ElectraNet has a small number of overhead high-voltage transmission lines that cross South Australian rivers and harbours.

Recreational and professional sailors should research the existence of overhead powerlines prior to transporting and sailing their recreational vessels, and dismantle masts where applicable.

Skippers of motorised vessels with large aerials and other protrusions should be mindful of overhead powerlines.

The 4.6 metre maximum height limit applies when transporting boats on roads and into marinas, and when manoeuvring on boat ramps.

Sailors must be conversant with the highest astrological tide and the Australian Height Datum (AHD) in calculating minimum clearance distances.
