...going solo in a 6.4m boat in the predicted conditions won't be fun

Belly Fish is right, on that forecast its looking pretty choppy.  If it stays SSW all weekend you could try the Sound side of Garden Island, but it will be really choppy getting there.  That cross wind isn't going to make solo launch/retrieve that much fun either.  Weather's been pretty lousy lately.

Woodie Point would be the best place to Launch - good facilities.  Would suggest picking a good week day and going down to practice when the ramp isn't as crowded and to test everything works as it should.  Not sure what the boat is or what your experience is, but in my experience a new boat has a new routine that takes some time to become second nature.  Check and recheck everything.  You may also want to think about a CPBA membership next door to the public ramp - not that expensive but really useful for a solo boaty.  On busy days the bosun there helps with launch and retrieve and Torr does a good job.  Other members I've also found to be really helpful and generally not as crowded.

I too do a lot of solo boating with a 6.4m glass boat (6.3 actually) and have no problems launch and retrieve, in fact these days when I do have a decky I reckon it takes me longer!!

Usual stuff too - when you are on your own elevate your safety - log on/off, jackets on, epirb close to hand, no uneccessary risks, ALWAYS be prepared to turn around and come back in or not launch at all if it looks hairy.  Might just be you, but if you get into trouble you will be endangering others that that may have to rescue you.

Congrat on the new boat by the way.

 Agree with everything said

when new to boating or even if an old salt with a new boat, my advice would be "learn your rig" you'll just know one day when you truly trust it - how it rides, how the swell and water 'feels' in a following sea etc etc - when you know your boat you can take it out in pretty much anything....until then apply the old rule of 15.....1.5m swell, 1.5m seas and 15knt winds (if any two are above this, even if only a little, then stay home....it might not be dangerous but it won't be comfortable!)

best advice i ever got was do 15-20 hours on the river learning how to handle your boat. Learning how it handles at slow speed is just as important as flat out....in the river you can learn most things, except maybe how to handle a following sea or a big swell.

 ive been out in similar weather in my old 6m fibreglass and hid in behind south end of garden island. Only prob was everyone else did the same and it's not that big of a space. Will be lumpy crossing from woodies and be slow going, but I felt safe enough as no swell on top.

 Cool, thanks everyone. I know when I said new boat everyone thinks you're a novice. As this is a new-to-me boat I have a little more experience up my sleeve and have taken this boat out from two rocks, hillarys and the river no problem solo. I agree with Broady that launch and retrieve solo is easy enough when you have your system. 

I was more looking for info on unfamiliar waters.

I'll do what I have always done, pick the days that suit me. Was just wondering if Garden Island offered protection in the sound with this sort of weather pattern. And no, I am not too good for the river, the kids love it there. It just takes so damn long to get anywhere if you follow the rules!
