Any open charters on western Lake Michigan?

[mad_max]

Does anybody know of any charter captains on Lake Michigan (particularly Milwaukee/Racine area) who run "open charters" where the 4-6 people they take on an offshore trip aren't necessarily in the same party - people just book their reservation at whatever the per-person price is until the boat fills up? I'm trying to find something where I split the cost of the trip with several other fisherman but don't have to assemble a party of several people. I've seen captains elsewhere run their charter operations this way and was wondering if there's a similar opportunity anywhere on the western side of Lake Michigan?
