If it's the boat in your profile pic I'd recommend Boatworks. Would be a nice trip south from Moreton Bay too.
Thanks mate, but I don't think we would make it clear of the powerline at the Logan River.
The top of the aerial on my mast to the waterline is 22.5m.
Give a bit of wiggle room and call it 23m.
The Alan Lucas bible shows 20.3m HAT.
