No problem at all. I went to Long Island and the Mole group in an 11 footer. Anything under 15 knots and you are fine. The outer islands (hook and Whitsunday) provide great swell protection so it is only chop you need to be concerned about. The main channel between the inner and outer islands is a little more hazardous ,but you can still get out there on the calmer days.
Also, try trolling some lures around the coastline to Cannonvale's nth. You will pick up coral trout in the areas where bommies are present and cod on the flats. As well as other species.
There are two ramps in Cannonvale and one at shute harbour. There is one at the sailing club in Airlie Beach central ,however not sure of its status with the marina development. I would suggest the shute hatbor ramp for island access and the cannonvale ramps if you want to fish inshore. I have recently moved from Airlie Beach after 15 years there.
You are in for a treat on the water with some spectacular landscapes.
Good luck and happy fishing.
