kayaking question

[nshore]

I am new to kayaking and I was thinking of trying a little paddling on the lake. My plan is to try a mid-week day, stay close to shore and put in at the Alton Bay Boat ramp.. My question is,...how much distance could I expect travel in an hour (in mi.).....I am in reasonably good shape (at least that's my opinion.. )... Thanks in advance, this will really help me plan my day..
