Thanks all for these most useful replies. I’m feeling so much more cautious than before I started this thread. Safety is indeed the bottom line. Though it’s about fun too!
Thanks for sharing about your boat karen2. I’ve owned 3 kayaks - a 4.2m fibreglass Solution Escape (fat deep boat that I liked except for sliding rudder controls), a Finn Affinity sit on top, and currently a Bay Sports Expedition Zero. All paddled almost entirely on the river. The Expedition Zero would perhaps have been okay for Magnetic Island trips, but I’m not sure as it has a fairly flat bottom, cramps my feet a bit like your boat, and overall doesn’t seem the best kayak for me to start out sea paddling with. I wanted 2 kayaks anyway so friends who don’t have a kayak can join me, so I’ve just bought another one.
My new kayak - just started on its road journey to me from Wollongong - is an Australis Iguana. I expect that may not meet with great approval here as it’s nothing like a Current Designs Caribou (which looks amazing btw) or other slender & elegant craft that seem to be popular amongst serious sea kayakers. I prioritised stable and seaworthy, which the Iguana clearly is - I have quite given up caring about speed! I know I will feel confident in my initial forays into choppy seas in this. What clinched the deal for me is that it is modular, so I can just pop a 16 foot sea kayak in the back of my SUV and head for the beach. The best kayak is the one that I actually paddle, and I know that convenience will help me a lot in paddling regularly.
Here’s a link to the Iguana, which has been paddled 2000km around the southern tip of Africa by Beau Miles. Dave at Australis told me last week that a few of them are currently being paddled on an expedition in the Northwest Passage:
And from Beau Miles’ 2007 diary about the Iguana: “Kayak rolling brilliantly in side, stem and stern busting waves. Happy with beautiful kayak… The Kayak (Australis Iguana) is simply amazing and capable of going around the world - I could have sold her 10 times already. I take my hat off to John, Dave and the Australis Crew in Wollongong for creating one beautiful craft.”
I think it should get me to Magnetic Island
