The Chicago to Mackinac Race is one of the ultimate tests of preparation, endurance, and performance.
333 miles up Lake Michigan demands more than just skill. It demands the right sails, the right setup, and a plan to handle whatever the lake throws your way. Last year’s race was a reminder of how quickly conditions can change: a 50-knot squall line led to a man overboard, multiple dismastings, and some very tough sailing. The teams that were prepared, and had the right gear, made it through.
We’ve helped our customers not just survive, but thrive. Maverick, an Andrews 80 equipped with our sails, set a new overall race record in 2023. And they’re not alone. Our sails have powered multiple teams to overall wins under ORC, thanks to well-planned inventories and optimized configurations tailored to real-world conditions.

Whether you’re in the racing or cruising division, the right preparation and sail choices can make your Mac race faster, smoother, and more successful.
New Sails, Built for the Mac
There’s still time to order sails for this year’s race. We build sails specifically for the conditions you’re likely to face: fast in the light stuff, strong and stable when the breeze picks up, and shaped for long-distance efficiency.
Whether you need one final piece of the puzzle or a full overhaul of your rating certificate, we can get you sorted in time for the start.
Our EM2 Composite Membranes are purpose-built for long races like the Mac. They are lightweight, strong, and able to maintain their shape through hours of pressure changes.

ORC Setup and Optimization
If you’re racing under ORC, your sail inventory and configuration matter. We understand the rule and how to balance rating optimization with real performance. We’ve helped multiple programs tune their inventories to win, not just look good on paper.
We also work with cruising division teams to optimize sails within the specific rules and limitations of the cruising section. Whether that means maximizing performance under sail restrictions, designing around heavier boats, or creating a simpler, easier-to-handle sail plan, we can help.

Strategy: Get Everything Out of the Boat
Winning the Mac isn’t just about surviving. It’s about finding speed all the way to the island. Smart preparation makes the difference.
Code Zeros and Light-Air Sails
We’ve unlocked how to make our code sails more versatile and more effective under ORC. These new designs have evolved from light-air reaching tools into fully capable upwind sails. We carefully match sizing and mid-girth to what your boat needs to maximize rating efficiency and real-world performance.
Genoa and Spinnaker Staysails
Staysails add free sail area with minimal rating impact. These sails give a noticeable speed boost in reaching and running conditions. They’re often the best bang for your buck to pick up a few tenths and get on the podium.
Heavy-Air Prep
The Mac fleet has been a magnet for squall lines the past few years. You don’t want to be the boat that drops out with sail damage and misses out on the rum party. Talk to us about sails that stay fast when it blows.
Inventory Planning
Getting the right pieces into your crossover chart ensures you’re ready for whatever the lake throws at you, without taking unnecessary rating or weight hits from carrying excess sails. We focus on maximizing range to minimize sail changes and keep you fast. We can work with what you have and fill in the gaps.

The Island Is Waiting. Be Ready.
There’s still time to get your sails dialed in, optimize your setup, and prepare for the race ahead. Whether you’re chasing the podium or just looking to finish strong, the right sails and the right prep make all the difference.
