There are four events that don't conflict with the Tiger one-design racing in HCA Division 10/16 - Tawas I (June 23-24), Benton Harbor (Aug 11-12), Caseville I (Aug 25-26), and Caseville II (Sept 22-23).

Tawas II is a possibility, too - depends on when the Austin Lake Hobie Fleet has their regatta (tentatively Sept 8-9)

Those dates are your best chances of getting the Detroit F-18 (Tigers) out.
