By Bryan Crabtree, Charleston Deepwater Real Estate Expert
One of the toughest problems with deepwater listings—in Charleston and frankly anywhere along the coast—is that most real estate agents have little to no idea what they’re actually selling.
They sell the house.
They talk about the view.
They vaguely point toward a dock “over there.”
But what serious boat owners want to know is something very different:
What’s the depth at low tide?
What’s the actual navigation route?
Are there bridge restrictions?
Is this truly deepwater—or just labeled that way?
Here’s the truth:
“Deepwater” technically means at least 6 feet at low tide. That’s the minimum bar.
But over time, the term has been diluted. Today, you’ll see listings described as “deepwater” that might only have 1.5 to 2 feet at low tide—barely navigable, if at all.
That distinction matters.
I own a 44’ catamaran sailboat with a 74’ mast, drawing about 4’4” light and roughly 5’ fully loaded, with a 25’ beam. I’ve spent years navigating everything from Charleston’s creeks to the Atlantic and Caribbean, logging over 25,000 miles of deepwater experience, including more than 15,000 miles on my current vessel alone.
And I can tell you this:
👉 Get it wrong, and you’ll be dealing with mud in your filters, grounding issues, and constant frustration.
👉 Get it right, and it’s pure freedom.
That’s why, when waterfront property is involved, you don’t just need a Realtor—you need someone who understands water.
Some people call me “Captain Bryan” or “Captain Crabtree.” I don’t carry a captain’s license, but I easily could. More importantly, I have something far more valuable: real-world experience.
When I evaluate a waterfront property, I don’t start with the house.
I start with Garmin and Navionics charts.
Because if the water doesn’t work—the property doesn’t work.
Understanding Charleston Tides (Why This Matters)
Charleston operates on a semi-diurnal tidal cycle:
Two high tides and two low tides daily
Average tidal swing: 5–6 feet
That means:
A dock showing 10 feet at high tide could be 4 feet or less at low tide
Creek depth depends on proximity to main channels, flow, and bottom conditions
👉 For serious boaters, low tide is the only number that matters
Daniel Island, Beresford Hall & Clements Ferry Corridor
Some of the most consistent deepwater opportunities exist along the Wando River system:
Daniel Island (riverfront sections)
Beresford Hall (Nowell Creek)
River Reach (Clements Ferry)
St. Thomas Point
Beresford Creek Landing
These areas benefit from:
Proximity to a federally maintained channel
Reliable depth for 5’+ draft vessels (property dependent)
Only one bridge restriction:
👉 Arthur Ravenel Bridge (~187’ clearance)
Ideal for both:
✔ Sailboats with tall rigs
✔ Large sportfishers with outriggers
Intracoastal Waterway – Isle of Palms & Wild Dunes
The ICW near Isle of Palms offers legitimate options.
A prime example:
👉 27 Waterway Island Drive (Wild Dunes)
This area provides:
Deepwater along the ICW
Protected conditions
Strong access to the ocean
⚠️ But there’s a catch:
Dewees Inlet requires experienced navigation
Constantly shifting sandbars
Moving channels
Not forgiving for inexperienced operators
Bridge Strategy: What Your Mast Dictates
For boats under ~65’:
Isle of Palms Connector Bridge
Sullivan’s Island Swing Bridge (open = no restriction)
This opens:
👉 Direct access to Charleston Harbor
👉 Deep water all the way to the Atlantic
For taller rigs:
👉 Harbor, Wando, and ICW access becomes critical
Stono River: A Quiet Power Player
Often overlooked, the Stono River system offers excellent boating:
Riverland Terrace
Headquarters Plantation
Sylvan Shores
S. Edgewater Drive (West Ashley)
Extending to Stono Ferry in Hollywood
These areas offer:
Wide river navigation
Strong tidal flow
Consistent depth in many sections
Bohicket Creek: One of the Best in Charleston
Located between Johns and Wadmalaw Island:
Bohicket Road corridor
Betsy Kerrison Parkway estates
Why it stands out:
✔ Consistent depth
✔ Wide, stable channel
✔ Direct ocean access
✔ No inlet volatility like Dewees
👉 One of the best true deepwater environments for both sail and power

Final Thought
Charleston offers some of the best boating real estate on the East Coast—but only if you understand:
Tides
Depth at low water
Navigation routes
Bridge clearance
Because in this market:
👉 “Waterfront” is common
👉 True deepwater is rare
About Bryan Crabtree – Waterfront Real Estate Specialist
Bryan Crabtree is a Charleston real estate expert with more than 27 years of experience, over 5,500 homes sold, and more than $1 billion in career sales. But what truly sets him apart in the coastal market is something most agents simply don’t have—real-world boating and navigation experience.
Having logged more than 25,000 miles at sea, including over 15,000 miles on his current 44’ sailing catamaran, Bryan understands waterfront property from a perspective few real estate professionals can offer. From shallow tidal creeks to open ocean passages, he has navigated the same conditions his clients must evaluate when purchasing a deepwater home.
Bryan approaches waterfront listings differently. Before discussing price, finishes, or marketing strategy, he evaluates the water itself—using tools like Garmin and Navionics to analyze depth, tidal impact, navigation routes, and real-world usability. His process ensures that a property isn’t just beautiful—it actually works for the vessel it’s meant to serve.
Known by many as “Captain Bryan” or “Captain Crabtree,” he has built a reputation as one of the few agents in Charleston who can confidently advise buyers with larger vessels, including sailboats with tall rigs and deep drafts, as well as sportfishing yachts and cruising boats.
For Bryan, real estate is not just about selling homes—it’s about aligning lifestyle with reality. And when the water is part of that lifestyle, there is no substitute for experience.
