Show up, fenders out at waterline, light turns green, go all the way in, avoid the few nice hull gouging bolts, grab the ropes on the side, wait for the green light, go out. Go to the draw bridge, wait up to 5 minutes or until there is no sign of a train. Then call 617-222-5986 to wake the guy up. VHF is useless. Beware of the weekday rush hour, when the bridge will not open. You should clear the next draw bridge at the Museum of Science. PUT YOUR VHF ANTENNA DOWN. It doesn't. Unless you are in a dingy, you are taking a cab there. IF you might be able to squeak under the bridge at mean low tide, you will be stuck there in minutes waiting for the next mean low tide to squeak back out.
