Hi.
Here's our problem if we put the name on them. We have only so many buoys (about 16 to cover 13 wrecks). If we lose the one on the Barnum, it may get moved to the Cedarville because that is more popular than the Barnum or attrition may bring us down to less buoys than we need. A decision then has to be made as to what wreck gets one. If we were NOAA, we would have acess to as many buoys as we need. We don't. But for the gift of these, we'd be back to jugs, balls and anything else we rummage up. Also, when we start out in the am to mark them, we have gotten on the Lake Michigan side of the Bridge only to find the water too rough but we can still go to the Huron. If we only have buoys labeled for the Ward and McBrier, we cannot put them on the Cedarville. It is not practical to put 10 or so buoys and varying lengths of line on the boat. So we waste a day and go home. I hope you understand, we all agree that labeling would be good (and it has been tried). It just has too many practical limitations given available funding (none).
There really should not be much confusion about the locations (except perhaps the Cedarville bow/stern if only one buoy and maybe the Ward) because of modern GPS. However, that means you need to have good numbers and some publications have limitations. Feltner numbers are derived from LORAN numbers and the translation loses something. Similarly, some popular books have bad numbers, sometimes because they just repeat the Feltner or other compromised source.
The association has a booklet with accurate numbers it has gathered by sitting directly over its buoys. With drift, they could be off a few feet but they certainly should distinguish the Barnum from the Cedarville. It is distributed by it or the MUPC at most Midwest regional shows.
If you want the booklet, contact the St Ig Chamber of Commerce or PM me and I will send it to you (assuming I can handle the requests). If anyone wants it, I also have a spreadsheet in Excel listing and comparing all the numbers collected by the Association, used by Straits Scuba, Abyss Charters and cited in most publications (Feltner, Kohl, et al). By comparing the numbers you get a pretty good idea as to what is accurate and what is not. Be cautious of the numbers in the MUPC booklet, they are mostly wrong as to the Straits (we are working to fix that).
Hope this helps explain why some things are done the way they are.
 
How many are needed and what is a rough cost per piece? Could these be purchased at a Home Depot?

You can buy shackles individually at hardware stores and I suppose at something like Home Depot. Better prices are from specialty stores on the net. Google "galvanized shackles" and some sites will pop up. They may have a minimum quanity but the price is a fraction of the individual cost.

As to the amount, any amount is good, these get eaten up mostly because the shackle pin gets lost at depth and renders the shackle useless. We could use 24-36 at least but any amount is great.

Ah Ha!!

Makes Sense!
 
The weather in the Straits was very good this weekend. Mostly calm, flat water with little or no current and sunshine.
More progress was made on placing buoys. Additional wrecks buoyed are: McBrier (engine), Sandusky (very temporary mooring pending installation of permanent off wreck mooring) and Eber Ward (bow).
Those previously buoyed are all still up: Eber Ward (stern), Cedarville (bow), Barnum (engine), Maitland (bow), Young (bow) and Minneapolis (engine).
There is also a light weight temporary line marked by a jug on the stern of the Cedarville (courtesy DAB and others).
 
Buoys in Straits of Mackinac June 29 Update.
Because of weather conditions this last weekend, no new buoys were placed. There was a west wind with whitecapping and strong surface (and sub-surface) currents on several wrecks. The Maitland buoy could not be located but it may still be in place and was just difficult to see with whitecaps and waves. The Sandusky buoy has lost the float holding the tagline at the surface, it is now floating about 1 foot below the surface when a current is running. The Minneapolis 3/4" poly line has lost one of three strands. It will still hold small boats but is unlikely to hold large displacement vessels. The stern buoy is still only a jug with a 1/2" line. Hopefully this next holiday weekend the rest of the wrecks will be buoyed and repairs made where required.
Special thanks to Cobalt Blue for the very generous donation of shackles to the shipwreck association.
 
Sorry, the reference to the "stern buoy" is to the Cedarville stern.
 
By the close of the 4th of July holiday, a buoy was placed on the Northwest. That means that everything (except the Stalker) in the Straits (Northwest, McBrier, Maitland, Ward (2 buoys), Minneaplois, Young, Cedarville (bow) and Barnum have all had at least one buoy placed. On Saturday, the Maitland buoy could not be found amid whitecaps and is presumed lost. It will be replaced asap. The Minneapolis buoy went missing last week and is being replaced today (Tuesday) and the Stalker is expected to be buoyed today as well. An additonal buoy remains to be placed on the Cedarville stern and it should be done in the next week to 10 days. One piece of good news is that someone found the Minneapolis buoy and turned it over to the Cheyboygan sheriff dept that returned it to the preserve committee.
 
Sorry, I forgot to mention that the Sandusky buoy has been relocated to the starboard stern. This temporary location is beleived stronger than former attachment points near the bow. Divers used to arriving nearer the bow should keep this in mind.
