"The Whiddens have five generations of legacy on that property."
Mark Spurgeon of Boca Grande Real Estate said that in February 2025, the same week his firm priced Whidden's Marina at $17.5 million. The marina sits at 190 1st Street East, at the edge of the Boca Grande Yacht Basin, an easy walk from Harbor Drive itself. It has stayed in one family's hands since Sam Whidden opened it in 1926.
If you live along Harbor Drive or the Waterways, you likely already knew the marina was for sale. What's easy to miss is what actually protects the version of the marina you've grown used to, and what doesn't.
Two Marinas, One Working Harbor
Harbor Drive runs past two marinas that have almost nothing in common except the water they share. At 220 Harbor Drive sits Boca Grande Marina, formerly Miller's Marina, a full-service operation with fine dining upstairs at the Eagle Grille and a casual dockside menu at Miller's Dockside Bar & Grille below it. Boat slips, fuel, a ship's store, the whole modern package.
Whidden's is the other kind of marina. Goats and orchids greet you at the entrance. The gift shop windows still hold products from decades ago. A sign inside reads "Sity Hall," because on this island, if something happened, you heard about it at Whidden's first. The building doubles as the Gasparilla Island Maritime Museum, which operates on a lease from the Whidden family rather than owning the ground it sits on.
| Marina | Address | Character | Status |
|---|---|---|---|
| Boca Grande Marina | 220 Harbor Drive | Full-service slips, two restaurants, modernized dockage | Operating |
| Whidden's Marina | 190 1st Street East | Family-run since 1926, bait and tackle shop, attached maritime museum | Listed for $17.5 million since February 2025 |
The two marinas have coexisted for decades because nobody had to choose between them. That's the arrangement Harbor Drive residents have taken for granted, and it's the arrangement now sitting on the open market.
Five Generations, One Museum
Sam Whidden built more than a dock. In its early years the marina was a dance hall and restaurant, the kind of place with a jukebox and a dinner crowd that stayed until the small hours. When Sam's wife Leslie died in 1940, he closed the restaurant and ran the property as more of a general store, then reopened the dining room during World War II to serve soldiers stationed at the island's south end port, according to a Boca Beacon profile of the Whidden family.
After Sam died in 1978, his daughters, Isabelle and Barbara, kept the marina running. On December 28, 2000, Sam's 100th birthday, Whidden's Marina was added to the National Register of Historic Places. The following year the Gasparilla Island Maritime Museum opened inside the property, according to the Boca Beacon's account of the family's history. Isabelle's daughter Melissa and her husband Sam Steyer raised three children on the docks, and every one of Isabelle's children, along with Barbara's son, has had a hand in keeping the place alive.
That's what "five generations of legacy" actually means on Harbor Drive. It isn't a marketing phrase. It's a specific count of people who grew up bagging bait and manning the register at the same building now carrying an asking price.
The Museum That Doesn't Own Its Building
Here's the detail that's easy to lose in the sale coverage. The Gasparilla Island Maritime Museum occupies part of the Whidden's property and tells the story of the island's fishing and boatbuilding history, but it doesn't own the walls around it. The museum operates on a lease from the Whidden family, a detail folded quietly into the same coverage that announced the $17.5 million asking price.
That distinction hasn't mattered much across a century of continuous family ownership. It matters now. If the marina sells, the museum's future becomes a negotiation with whoever holds the deed, not a given. The docks, the exhibits, the goats, none of it comes with a guarantee that survives a change in ownership.
What "Marina Commercial" Actually Allows
The listing itself gives away the mechanism. Whidden's sits on 0.94 acres, zoned marina commercial, with both wet and dry slips across multiple structures. That's the same zoning classification that covers Boca Grande Marina a few blocks up Harbor Drive, the fully modernized version of a working marina.
Nothing in that zoning code preserves goats, orchids, or a gift shop window frozen in 1970. Marina commercial zoning permits a range of intensities, from a bait shop with a museum attached to a rebuilt facility with the footprint and amenity list of its neighbor. The Old Florida character that makes Whidden's feel different from Boca Grande Marina has never been a function of the zoning map. It's been a function of one family choosing, generation after generation, not to build to the maximum the zoning would allow.
That choice is now for sale along with the acreage.
The Season Nobody Sees
August on Harbor Drive is the quiet before the calendar fills back in. The core of tarpon season, April through July, has passed, though charter captains describe a late-season bite that continues into the fall as fish linger near the Pass. Boat traffic through the Yacht Basin has thinned. This is the version of Harbor Drive residents actually get to themselves, before the visitor traffic that a viral TikTok video has been sending toward these docks picks back up with the cooler months.
The Boca Grande Area Chamber of Commerce held its season-opening mixer right on Whidden's docks in October 2024, the kind of civic gathering that assumes the ground under everyone's feet will still belong to the same family the next time the invitation goes out. Nothing about a marina commercial zoning designation or a museum's lease agreement guarantees that assumption twice in a row. The docks will still be there whenever the next mixer happens. Who owns them by then, and what they choose to build beside that National Register plaque, is the open question every neighbor walking past 190 1st Street East this month is quietly asking.
Harbor Drive has spent a century holding two different marinas on two different clocks in the same small stretch of water. One clock runs on restaurant hours and modernized slips. The other has run on family succession, museum leases, and a set of choices nobody was required to make. Right now, mid-August, with the pass quieting down, the neighborhood is living through a season of an arrangement that was never guaranteed to outlast the family that built it.
Whatever comes next for Whidden's, the harbor itself isn't going anywhere. The people who live along it are the ones who will notice first if the character does.
If you're curious what any of this means for property values along Harbor Drive and the Waterways, or you simply want a local read on what's changing in the neighborhood, the Steffan Sieglaff Team knows this stretch of water block by block. How much is your home worth?
