Aquabelle, if you are coming inside the Bay and want to take your time going up inside, then it would be easiest to come up the main channel past Jacobs Well, and where I am at Horizon Shores, then continue on up and then duck across to north Straddie via the channel between Karragarra and Macleay Islands, quite a nice stopover in itself. Canaipa passage has some rather shallow spots, one in particular just south of the first green beacon as you come past the Slipping Sands anchorage. No 120 in the guide below.
Ideally grab a recent copy of the Beacon To Beacon map guide, if you can, as there is more info in there re the anchorages. Any service station or bookshop would have it.
Once over near north straddle, (past the Eric Early Light), then straight up to Peel Island is a nice trip. If you stop off at the Price Anchorage, 109, (you would get in at anything above half tide I think), you might see turtles and/or Dugong. The next stopover above that is the Blaksley Anchorage, 105, which is good for a day stop and swim, (nice beach), but dodgy for overnight, as is Peel unless very settled Northerly weather forecast. If weather doubtful, then yes, the One Mile near the little Ships club, 96, as Insequent mentioned, and it is quite sheltered from NE throught to SE, but Myora, 94, a bit further along has more room and better protection from the South. Then you can loop back down to Peel, and pass East of it and head north, ( take it from me, the Rous Channel is not a shortcut), where you have options of Manly, (they have pump out fac), Green Island 90, or St Helena, 87, then it's a fairly long leg to get up to Tangalooma, 75, (about a couple of hours maybe), which is your last anchorage, behind the wrecks, before you exit the Bay heading North to Mooloolabah. Benn might chime in with some specific info re entering Mooloolabah, this being his home port, and I have never gone up that far...?
But definitely try to get a Beacon to Beacon if you can, it helps a lot even with a good GPS. The numbers for the anchorages I added above relate to this guide book. The chips go out of date quite quickly in this Bay and that guide is updated every year, and has helpful, overhead photos of the anchorages etc.
The current latest is 9th edition I think. From 7 up would still be ok, however if someone offered you one. The bookshops and chandleries, and servos all have the latest of course.
