Our "Speed Floor" is dependent on what we are doing and where we are. Out of choice we like to leave early and anchor mid afternoon. If we are on the Chesapeake during the summer this also is to avoid being underway when the thunder storms are most likely. If we are in New England we like to get in in time to go ashore and play tourist or just wander around. On the other hand if we are just day sailing we will often drift for a while unless it looks like we will be there all night or it is just too damn hot.
