For Jane's birthday this year I bought her a Hobie Mirage Outback kayak, that one can pedal as well as paddle. This is a great thing for people with back problems. The pedal system has a novel design, as well as being powerful and fast.       (Okay, so her birthday really isn't until August)

Jane has just launched and is getting her "sea-legs"

After a few minutes she was zooming around me (taken from the canoe -- our cabins are behind her)
