We actually did this for the first time last summer. You should know the weather forecast because it can cause ripples in the water, you should know where the safety points are in case of trouble, you should understand that this type of sport is all about patience and balance. We rented a two person Kayak and we discussed our rowing technique (i.e. side of the boat to start the paddle, consistent strokes). It was a blast and we will do it again this summer.
