Hi guys, I have been paddling for a few years now in borrowed boats and now it's time to buy my own. I have mostly paddled Australian made Pittaraks and a few different plastic boats. I'm 6'3'' tall and 90kgs so I find I get a bit cramped in a key hole cockpit boat like a pittarak but I have found most of the plastic boats to be slow pigs that are hard to turn. I understand a small amount of "tech talk" but please keep it simple. I need a boat that's fairly quick and still manouverable, has ample storage for a week long expedition, a large-ish cockpit and can handle rough seas. I plan on using it to paddle from mainland Australia to Tasmania across Bass Strait. I am looking at a Delta Fifteen-5 but am a little concerned about its speed, or a Delta Seventeen. Any and all comments/suggestions/advice would be greatly appreciated.
