Hastings Yacht Club or Blind Bight Boat Ramp on Google Maps (satellite view and 360 photos)
look similar to Inverlock Boat Ramp - i.e. worth trying
...unless someone already had bad experience there or sailing is forbidden?

Looking for flat water spots

Inverlock is almost 2 hour drive and those 2 spots are twice closer, which makes them attractive.
I can usually spend only half a day for a windsurfing trip and not the whole day

Any advice?

Thank you!

It has a huge tide and low tide is very low. Turns into small channels that is really only for power boats. Cowes yacht club run a race around French island for the cats. I will ask some of the guys, they race for something like 8 hours straight and run into the sandbanks around the other side

I finally found the post from when we did an expedition to Westernport Bay, Eastern Channel on 04/03 2009

I also did a tinny boat trip a few months later with Tom Chalko and explored right down past French Island. Not much more to report except what we already knew. It needs a very low tide, and that is rare to never on a strong NW wind.

I'm still searching for the video my son made with no luck so far.
