Hey all, Gonna attempt a launch at the neighborhood ramp this weekend. Its a seldom used ramp with about 5ft depth at high tide. I did a test run today and was floating fine at 2 hours past low tide, so I am figuring that I may be safe if I launch and retrieve around high tide, or before low tide. My big question here deals with Power lines and bridges. I normally launch from a marina with a straight shot to the bay, with no over head lines or bridges, so I never have to worry about height clearance. However, the spot I'll be leaving from this weekend has overhead lines, a clearance of 32ft, a draw bridge, and an old rail road bridge that I've never actually seen in its closed position (e.g. its always open). The power lines concern me as I am not quite sure where my "Height" is being measured. I'm told the boat has a 28' mast, so should I be concerned with 32ft power lines? I'm assuming the mast is sitting a good 4 to 6 feet off the water, putting me between 32 and 34ft total height. If this is the case, I'm going to leave an hour and 30 minutes earlier than I originally wanted to and go back to the trusty "no overhead problems" straight shot to the bay. 
Thanks, Ken
