Hello Catagory5
welcome to the forum
What type of cat do you have? What condition is she in?
Have you done the trip with someone else before? If not, might be good to do a reconnaissance to familiarise yourself with the Bay and her moods plus landmarks on Moreton and the mainland.
What preparations and gear are you planning on having aboard?
If it is an off-the-beach cat, then you should have a good turn of speed and have no problem whatsoever making Moreton in a day. If you're at all concerned, aim for the Sand Hills first, then stick close to the island as you make your way up to Tangalooma. Depth, for you, won't be an issue. Personally, I can't see any value in going to Peel first if your ultimate destination is Moreton. Value yes, in terms of it being a nice place to visit, but no advantage in ultimately getting closer to Moreton.
Why have you organised a mooring rather than just pulling the boat up on the beach?
