There is not set rocker, each design is different. Off the top of my head I don't remember what each boat has but the new Short Shot, Long Shot and Firefly will be closest to what you have in mind. I am very impressed with the new Short Shot and I am about to start a new boat based of it with some minor changes.
The new design is going to have a retractable skeg. I have been working on this idea off and on for at least two years and finally have it to a where I am happy with the design. I don't like rudders. They just complicate a simple design, but I understand the advantage in certain conditions. That is why I am working on the drop down skeg.
As for changing the design I offer no support for modifications. When you start making changes I have no control or idea of what you will do so I have no idea what the results will be. it is no longer my boat, but a new boat. Your changes could do nothing and it could be deadly, so I have had to adopt a 'you are own your own when you change it" policy.
Jeff,
Thanks for your reply. I definitely understand your position on any modifications to your designs. The Long Shot and the Firefly do look like the closest match to what I was mentioning. The jpeg files you use on Kudzucraft.com appear to indicate the amount of rocker, but I cannot make out the numbers on the bow and stern when it is blown up. Do both of those have 2-3 inches of rocker already? If so, I think it's pretty much what I had in mind rocker wise.
I also understand the desire to avoid rudders. That being said, I know that when I was paddling on the Gulf with 20 knot winds, using a rudder to maintain course allowed me to focus on forward strokes rather than corrective strokes or leans. A rudder may reduce speed, but I find corrective strokes and leans to take away more than a rudder. I'm not claiming to be "right" as much as saying that I prefer to focus on a forward stroke and moving forward given a choice. Rudders don't tend to help win any beauty contests, but they do help.
