I usually get 5-7mph on my Outback, but conditions must be perfect. I'm in a fairly calm area of water-virtually lake water.
I've never capsized because I am always ready to let go & or furl the sail a little... Your Hull will limit you to (in my opinion) around 7-8mph MAX. Revo owners would need to chime in.
Again, try it out first without the sidekicks. 8-10mph should be ideal for you to learn the in and outs of the Yak. Its the Gusts that you need to be prepared for!
Cheers for the reply.
I've been out twice now, though there was very little wind and I was averaging 2.5-4mph. I've just come back from the sea front, fully loaded and good to go, though again there's no wind
It's forcast to pick up later, we'll see. I've had just over 7mph peddling for short distances, though it's not worth the effort. You can cruise at 4-5 mph with the Turbo fins without much effort.
I was guessing 5-7mph as you've said.
