EP 139: 46 Sparks, Dream Center Console Build
Mike Grandonico didn't just buy a bigger boat—he engineered a fishing fortress. After 15 years of building boats with Bob Sparks, he commissioned a 46-foot center console that’s essentially a beefed-up Bahama, but with three-inch-thick tower legs, a refrigerated mezzanine seat, and zero sonar. The boat was designed for sailfishing and dead-bait dredging in the Bahamas, where visibility and simplicity trump tech. Mike’s radical choices—no buggy top, no dive door, no generator, no frills—were all deliberate. He prioritized durability, ease of maintenance, and comfort over luxury, even turning the mezzanine into a freezer box and the cabin into a climate-controlled rod storage vault. Despite having no sonar, he catches billfish consistently, relying on radar and bird sightings. His biggest regret? Not installing a Seakeeper. But for a man who once said, 'If God wanted us to have fiberglass boats, he would have given us fiberglass trees,' this is the perfect tool for the job: a no-nonsense, overbuilt, deeply personal machine built for the fish, not the show.
Built a 46-foot center console with three-inch-thick tower legs for maximum durability and presence
Eliminated sonar, generator, and dive door to keep the boat simple, low-maintenance, and dry
Designed a refrigerated mezzanine seat that doubles as a fish box and storage vault
Used a 12-volt system with no diesel or generator—saving weight, smell, and complexity
Fished without sonar and still caught multiple billfish per day by relying on radar and bird sightings
…and 3 more takeaways available in PodZeus
The Birth of a Dream Boat
“When I walked in, I was like, that's it.”
Design Philosophy: No Frills, All Function
“It's for fishermen. It's not for taking the wife and the wife's friends.”
The Tower: A Beast Built for the Sea
“I had a lot of cracking issues. So really I, I had gone back up to Palm Beach and it was repaired and then we'd break it again.”
The Mezzanine: A Seat That’s Also a Freezer
The entire mezzanine is a refrigerated 12-volt freezer box. It’s designed for comfort, fish storage, and crew ease—no more chest freezers on deck.
No Sonar, No Problem: Fishing the Edge
Despite having zero sonar, Mike catches billfish daily by relying on radar, bird sightings, and water patterns. He argues sonar doesn’t help on the edge where they fish.
“Um, I had a lot of cracking issues. So really I, I had gone back up to Palm beach and it was repaired and then we'd break it again.”
“It's for fishermen. It's not for taking the wife and the wife's friends.”
“You know, the boat's built for it. I mean, it has a spot for the sea keeper and it has a spot for the generator, but we made it to where it's all open. So it's all storage now.”
