Slip · Hilton Head Island
A deepwater slip in Windmill Harbour is among the most specific — and most negotiated — assets a Hilton Head Island home can carry. Buyers who understand how slip ownership works in this market move faster and negotiate with confidence; those who don't often discover the distinction only after going under contract.
Hilton Head Island sits at the confluence of the Intracoastal Waterway, Calibogue Sound, and Port Royal Sound — a geography that makes deepwater access not a luxury add-on, but a primary filter for a measurable segment of buyers. Among the island's boating communities, Windmill Harbour stands apart: a private, lock-protected marina on the island's north end with a fixed number of slips, a controlled water level that remains navigable regardless of tide, and a homeowners' association structure that ties slip ownership — or slip rights — directly to residential parcels within the community.
For out-of-state buyers searching deepwater slip availability in Windmill Harbour, the core question is rarely the boat. It is the property structure: does this home convey with a deeded slip, a slip lease, or no slip at all — and what does each mean for financing, cost, and resale? This page addresses that question directly, places it in the broader context of Hilton Head's waterfront market, and explains how COAST brokered by eXp Realty represents buyers through every layer of due diligence.
Slip · Hilton Head Island
Windmill Harbour is a gated marina community on the island's northwest shore, centered on a controlled-depth saltwater basin maintained by a lock system — one of only a handful of such marinas on the East Coast. The lock keeps interior water levels stable, allowing boats to float at consistent depth around the clock. Slips within the marina are individually numbered and, in many cases, separately deeded from the residential lot they are associated with. That distinction matters: a deeded slip is real property, titled in the owner's name, and can in some cases be conveyed, sold, or leased independently of the home. A slip lease or slip license, by contrast, is a contractual right assigned through the Windmill Harbour Owners' Association — it conveys use, not title.
When a listing describes a home as having a 'slip,' buyers should immediately ask four questions: Is the slip deeded or licensed? What is the recorded slip number? What are the current WHOA annual assessments for the slip? And is the slip currently occupied by a vessel under a sublease? The answers shape both the offer structure and the financing conversation — some lenders treat deeded slips as collateral; others do not. COAST brokered by eXp Realty routinely requests the WHOA resale package and slip documentation at the outset of any Windmill Harbour transaction.
Windmill Harbour is the island's most concentrated source of deeded residential slips, but it is not the only one. Sea Pines Resort, at the island's south end, includes Harbour Town Marina — a deep-water facility on Calibogue Sound where certain residential properties carry slip rights negotiated through Sea Pines Community Services Association. South Beach Marina Village, also within Sea Pines, offers a more casual waterfront setting on Braddock Cove. Palmetto Dunes, the mid-island oceanfront resort community, is crossed by an eleven-mile lagoon system that connects to Broad Creek; dock permits and private dock structures are common there, though they serve smaller vessels and kayaks rather than deepwater offshore boats. Hilton Head Plantation, on the island's north end, borders Port Royal Sound and includes Dolphin Head Recreation Area on the water; some parcels carry private dock rights through Beaufort County permitting.
The practical distinction for a buyer focused on Windmill Harbour is draft. Boats that require six feet or more of water at low tide have limited options on Hilton Head. The lock system in Windmill Harbour is specifically engineered to address this — it is the reason the community commands the attention it does among offshore cruisers and larger powerboat owners. Buyers comparing communities should verify current slip dimensions, maximum LOA and beam tolerances, and liveaboard policies as recorded in each community's governing documents, as these details vary and change over time.
Purchasing a slip home in Windmill Harbour involves two parallel due-diligence tracks that run simultaneously: the home itself and the slip. On the slip side, buyers should request and review the WHOA governing documents — Declaration of Covenants, Conditions, and Restrictions; the marina rules; current annual assessment schedule; and any capital reserve study. Slip assessments are separate from residential HOA dues and are billed independently. Buyers should confirm whether the slip carries any existing deferred maintenance obligations and whether the Harbour's lock system has scheduled capital projects that could affect assessments in the near term.
On the real property side, out-of-state buyers should be aware that South Carolina uses attorneys for closings — a licensed SC real estate attorney handles title examination and closing. Title insurance should be ordered to confirm the slip's legal description, its recorded ownership, and any encumbrances. Buyers financing through a lender will need to confirm how the lender treats the slip for appraisal and collateral purposes, particularly if the slip is deeded separately. COAST brokered by eXp Realty coordinates with buyer's counsel and lenders from contract through closing to ensure no documentation gap is discovered at the table. Note also that Windmill Harbour prohibits short-term rentals — the community's POA covenant enforces minimum lease terms, which means buyers should approach it as a primary or long-term-hold asset rather than an income property.
COAST brokered by eXp Realty was founded in 2022 by Rick Saba and Tristan O'Grady — two of Hilton Head Island's most active producers — and has since grown to represent the waterfront, resort, and high-value residential segments of the Lowcountry market.

COAST holds the #1 position among eXp Realty teams in South Carolina by volume, and the broader COAST eXp Luxury network — which includes Elevé Properties, the Kiser Jetton Group, David Carroll, and others — is active across the full spectrum of the island's waterfront inventory.
