A list of wobble factors here http://canoesouth.org/index.php?page=k1-stability your boat isn't on the list but it may help if someone says it is like a boat that is on the list. Note that wobble factors are only a guide and boat stability can also depend on your weight, seat height and how you feel on the day.

I also reckon that list doesn't provide fine enough detail down at the wobbly end - I've paddled several factor 1 boats, and there are significant differences between their stability.

Other factors especailly seat hight can have a massive effect on stability. The modern boats with platform seats all have fully adjustable seats, hight and angle. If a boat is too big for you it can also be a bit more "tippy"

Though it's worth noting that all platform seats in racing boats (that I've come across) put you higher up than you can get with an old fashioned bolt to the bottom seat. I have a nice low moulded seat in my very tippy boat (it's far nearer 0 than 2) which does make a huge difference to the stability.

Another factor (for me at least) is the shape of the hull. My Accelero is a bit rounded and relatively forgiving. Last week I paddled a (Regatta copy of a) Nelo Vanquish and the flatter sides make the boat more susceptible to waves/chop coming from the side.

To make my Accelero more stable I plan to take out the platform seat and put a nice foam seat on the platform. If it doesn't work out I can always put the platform seat back in but I expect the slightly lower and way more comfy seat to be an improvement, both in stability and comfort.

If you have a skinny,low volume boat then you sink more of it into the water and so the seat height relative to the water level is smaller than if you are in a wider boat.
Also, connectivity can make a difference.The moulded glass fibre seats in wide boats wrap around the sides of your bum giving more feedback, especially with edging whereas you feel you can fall off the side of a wooden or platform seat.

Just found this website which says it is a wobble factor 1 or "wooble" if you prefer http://www.kajakinfo.dk/Kapkajakker---wooble-1

As mentioned above, I have a moulded wrap around seat in my narrow tippy boat (though it's carbon/kevlar ;) ) - I find it far more comfortable than the flat seats, and as you say better control, though arguably it does inhibit rotation a bit.

Stability is very subjective and cannot really be described by a single number.

At our club we had two Stilleto K2's one labeled Canoe sport and one labeled by Baron they were both manufactured by Baron. Several people refused to paddle the Baron as it was far more wobbly?

I currently paddle a Nelo Vanquish wobble factor 2 however I find the boats with a wobble factor 9 /10 far more unstable.

I have to agree with Mike. I happily pootle around (let's call it "winter base training" :-)) in my Knysna Stiletto X which I've been told is basically a Jaguar (stability 2) in disguise, without drama, but get me in a Tor (stability 6) and it's utter chaos.

Similarly, the club has a load of Hobbys (stability 8 maybe?) - and I find one of them a right handful to paddle but all the others are fine. I was discussing it with somebody the other day at the club and they said that they also find one of the Hobbys a real handful. Must be a rogue boat we thought and dug it out to have a look at it - turns out though it's two different boats!

Or is it paddlers that should have a wobble factor? Judging by my efforts in the first 400 yards of the Hasler final, I'd be a 9. At best.

This may also due to something a friend of mine had with his Vajda Supersonic: his paddle was too short for him so he had to reach beyond his comfort limit to but the blade properly in the water. So it felt like his boat was really unstable whereas it was actually him leaning the boat out of balance that made things tippy. What also didn't help was the is quite a big bloke (1.98 cm or something) and he did barely fit in the cockpit. So his leg drive also pushed against the cockpit rim, unbalancing the boat.

When paddling an Epic Legacy he did not have the cockpit problems and after switching to a new, adjustable and longer wing paddle he felt a lot more stable. Though in the end he sold the Supersonic to buy an Epic 18X he is totally in love with ;-)

But it might be that your paddle is perfect for a smaller boat and the Hobby simply is too wide for you and that particular length of paddle?

Cheers,

Michiel
I do not think paddle length is the reason. It is true that it harder to put weight on the blade in the wider boat.

I think it is probally that the wobble factor 9 / 10 boats do not move as expected when I shift my weight through the stroke.
