In 2 weeks, I'm travelling to Port Douglas with the family to escape the colds of Melbourne.

I'm planning to bring my gear but would like to ask if anyone can help me with some info:
1 - Location: Im staying in Port Douglas and ideally I would like to sail close to town for family reasons (although I will have a hire car). What are the best spots? Can you sail 4mile beach, and if so, are there any restrictions to watch out for (tide, jellyfish, crocs, etc)?
2 - Wind Strength: The forecast and wind readings always seem to be 15 - 20knots. For me 20kts is fantastic while 15knots is disappointingly close...To make sure Im not dragging my gear up there for nothing, can anyone tell me if this actual the wind strength on the beach is lighter than the forecast / observations or are they pretty much right?
3 - Green Island: I have read all the reviews on Green Island and I would imagine the wind would be stronger here, if I was to go there is it OK to catch a ferry with your gear or do you need to make special arrangements. Also i understand tide is pretty important, when is the best tide? and will there be anyone else sailing?

Appreciate any information.

Hey FNQers, I'm headed up to Cairns for a long weekend this weekend, will be out at Green Island on Saturday, lots of green arrows on the graphs, and looks like high tide after lunch, so I assume it will be ON!?? Any need to worry about jellyfish this time of the year?

I'll be with family, so will probably just sneak away for a quick hour blast, does anyone know what kind of rental gear they have and prices?

Thanks
