It's a great boat the v10g3. Stability is a relative thing. I moved from a Fenn Elite ( which I never fell out of, which was a good thing because it was a bastard to remount) to the v10. It felt so planted on the water. I could adjust my paddle, do up my legrope etc, sitting in the boat.
Now I've moved to an NK storm 61, which doesn't have as much primary stability as the v10 but a lot of secondary stability. It is similar speed on flat water, but catches and holds runs more easily, especially the smaller organised bumps I tend to paddle in.
A lot of people will tell you to go for a more stable boat and they're probably right, but the challenge of having a good paddle in a tippier boat is what makes a paddle interesting. I have 2 boats, a Zeplin and the NK. The Zeplin is rock solid and in a more messy ocean is faster than the NK, but it feels like I'm cheating when I get back. The excitement isn't the same, the challenge isn't the same. Enjoy your new boat.
