Try to avoid docks while learning - much easier to rig, take off and return to a sandy or grassy shore.
The main thing is to be constantly aware of is the direction the wind is comming from. Once you get moving, apparent wind will be in play. If you do not have a wind indicator, I will give you one. To stop, turn directly into the wind. To go, turn off the wind by at least 45 degrees.
When we meet, I will go over the basics on paper, we will rig your H16 and then hit the water.
In the mean time, watch this 12 minute training video on sailing basics of the H16 - http://www.youtube.com/watch?v=PFliNR3wW_w
