it looks like the vests only have to be worn if your getting a special use permit to me.

Pierson said that standard additional restrictions for this Special Use Permit will include the following:
-No alcoholic beverages in “kegs” or on tap.
-No public address/music systems.
-U.S. Coast Guard approved Type I, II, III, or V personal flotation devices must be worn at all times unless person is below deck or in an enclosed cabin.
-No more than four persons per vessel will be allowed for each additional vessel over five. For example, seven vessels in a raft would be limited to a total of 58 persons in the raft.
-Additional conditions may be required if warranted by the scope of the special use.


and these looks like the rules for up to 5 boats

He noted that, effective lake-wide on July 18, 2008, and thereafter:
-No more than five boats will be permitted to be tied together.
-No more than fifty people will be allowed on any raft of boats.
-No raft of boats will be permitted within 150 feet of another raft.
-For purposes of these regulations, a raft of boats is defined as two or more boats tied together.


so basiclaly if you have 5 or less boats tied together you dont need a vest and can have a keg is the way i read it... you only need vests and cant have kegs if your using a special permit for 6 or more boats
