While we love to stop at South Haven, we grounded when entering a slip at the Muni Marina (museum side) last year in late June. Lake Michigan water levels were 17.4 inches lower, as of this March, than they were last June.
I don't think we will be back there unless Lake Michigan recovers or South Haven does some dredging.
Lake Macatawa (Holland) is a deep water port with plenty of depth for a 352. We have stayed at Eldean's Marina and were quite happy with their facilities.
"Sailor Tim" at Anything Sailing Forum
has a B361 at Eldean's Marina and he would be a good resource to answer any question you might have about the lake.
Are you the buyers of Wanderlust in Whitehall?
Good luck this season. We're crossing to Ludington this year and heading north in search of deeper water.
