The official Ski area is just north east of the mouth to the mandurah estuary,
The closest launch point is either the Marina (Paid) or Mary Street Lagoon,
Access to the beach from the water is only permitted at the Ski Takeoff area, This is just north of the "town beach" In Silversands,
Your not permitted to tow people from the Ramp to the ski area, Soo this whole arrangement is shithouse,, As you would need at least 2 cars, Because theres not trailer parking at Silversands..
Anyway, Enjoy. Dont break the rules as this is a awesome place for ski's run around, And the more people that break the rules, The less likely were going to be able to play in the ocean in this little bit of awesome,IE, Out of towners spoiling it for the locals = bad
