Default Draw Bridges - Grand Haven US 31 Draw Bridge Clearance

Hi All

My new boats home port is in Spring Lake, Michigan. To get there, I need to clear the U31 draw bridge. When I speak to the draw bridge authorities, they say the clearance is about 17 feet, and it also shows this on the actual bridge when you pass through (I am guessing that the scale is indicating the lowest clearance point on the bridge, at ends, not the arch). The nautical map shows 25 feet from datum clearance.

Here is my question, if anyone has experience with this particular bridge or other bridges. What is the current actual clearance? I have a Carver 404, which specs at about 18 feet, with whips down. I am pretty sure there are larger boats passing through the bridge, without it being lifted.

Obviously, being very cautious and having them lift it with each of my passages.

Any thoughts, experience or advice would be great, I have checked with a few of the local marinas, but they refer to the bridge authorities.

Thanks
Rich

I can't speak to the drawbridge as the only time I've dealt with it has been in traffic while waiting for it to go back down ;-) That said, my wife and I go for breakfast quite a bit at Jack's at the Holiday Inn on the east side of the bridge and I could swear I've seen some pretty large boats over there. I can't imagine that they all wait for the drawbridge though. Grand Isle seems like it would be the best place to ask, but it's weird that they all want to refer you to the bridge instead.

Hey Reardon

I'm late to the party but I live in Spring Lake, MI as well and have all my life. I am sure you have figured it out by now but clearance is just about 18' when closed depending on current water levels which will likely be down a little this year with the lack of snow. A client of mine has a 530 Voyager and makes it under but just barely with the antennas down. Just FYI in case someone else was wondering too.

Happy Boating!

Ok, we do not have a booth there, just going Friday afternoon and early evening to meet with some dealers and finance folks we work with on boat insurance for them to close their deals at the show.

Have a great time!

The bridge schedules to open every half hour between 6am and 10pm, if that helps.

Charlevoix is not 17', more like 12' or so, depending on levels....
