The main difference between the Innova Sunny inflatable kayak and the Innova Helios 2 inflatable kayak is as follows:
* If you paddle mostly with a partner, get the Helios 2
* If you paddle mostly solo, get the Sunny
When paddling the Helios 2, solo, you can pack the fore area with gear.
When paddling the Sunny with two, you may take on water on gusty days. Below are some photos of a gusty day in November -- two men in a Sunny.
