Grant’s Signature Racing Prepping Super Stock Raceboat Trio—And More

Grant and Kellie Bruggemann—the quiet couple behind Grant’s Signature Racing in Bradenton, Fla.—are taking a break from their powerboat rigging and building operations for the next few days. But for the company’s namesake and his wife, a “break” still means work. And in this case, that translates to testing the GC Racing 450R Factory Stock-class MTI 390XR raceboat with Miami-based owner/driver Willy Cabeza in Key Largo.

Cabeza and Bruggemann officially announced their partnership last month during the MTI Owners Fun Run to Hawks Cay in the Florida Keys. The first race of the 2024 season—the Race World Offshore 7 Mile Offshore Grand Prix in Marathon, Fla.—is a little more than two weeks away, So Bruggemann, who will throttle the GC Racing cat alongside Cabeza, is eager to get started.

“We are counting the days down the days to Marathon season-opener,” he said. “And GC Racing has a refreshed look fans will see for the first time there.”

Bruggemann and Cabeza are currently practicing and testing for the 2024 offshore racing season.

Managing and throttling one raceboat while keeping up with pleasure-boat rigging work would be more than enough for one shop, but not so for Bruggemann and company. They are currently prepping the Big East, CELSIUS and Northwing Super Stock-class raceboats for the upcoming season.

And those are just the Super Stock boats Grant’s Signature Racing has ready to start the season.

There’s never a dull moment at Grant’s Signature Racing.

“I’m also already ordering parts for another brand-new 32 Doug Wright Super Stock catamaran that we should be receiving in four to six weeks for rigging,” said Kellie Bruggemann.

On the pleasure-boat side of the business, the shop is finishing up a new 32-foot Doug Wright catamaran powered by Mercury Racing V-10 400R outboard engines. The catamaran is going to Maxed Out Marine in Lake Havasu City, Ariz.

The latest 32-foot Doug Wright pleasure cat rigged by Bruggemann and his crew boasts a pair of 400-hp V-10 outboards.

Earlier this week, Bruggemann and his team also finished prepping two Skater catamarans—Joe Castellano’s 388 and Chris LaMorte’s 36—for this weekend’s Florida Powerboat Club Tampa Bay Poker Run. LaMorte had Grant’s Signature Racing re-install his 36-footer’s freshly rebuilt transmissions as well as inspect the cat from bow to stern for the upcoming event season.

“I’m good to go this weekend,” he said. “I have not used the boat since the Joey Gratton New Year’s Day Fun Run so I am looking forward to doing some boating with friends this weekend.”
