Hi AndyL, welcome to the forum.
Great place to keep in contact and ensure you are in the right spot for a sail ( well most of the time anyway).
A lot of guys will be heading down to Marion today, sailing front beach and the lagoon. The lagoon is a brilliant spot for beginners/intermediates to hone their skills, providing flat water for gps and speed as well.
Also waves for bump and jump out the front beach.
Keep an eye on the forum as guys often post from down there letting you what live conditions are.
