Harbourfront elegance in Windmill Harbour.

Yes. The Windmill Harbour lock chamber measures 75 ft × 19 ft and the marina accommodates vessels up to 70 ft LOA, so a 45-foot hull passes comfortably — beam, draft and air draft are the figures to confirm against the chamber for your specific boat.

The hydraulic lock neutralises tidal change inside the basin, holding a constant eight-foot depth regardless of the tide outside. That is the point of the lock: you are not timing your departure or arrival around the water.

The lock opens on demand 24 hours a day with keycard access, so you can transit on your own schedule. Harbormaster-assisted lockage is available 8am–7pm if you prefer a hand.

Dockage accommodates vessels up to 70 ft LOA, and the lock chamber measures 75 ft × 19 ft. Beam and air draft are the practical limits for larger yachts — the 19-foot chamber width is the figure to measure against.

Slip ownership and conveyance are property-specific here rather than automatic with every home, so it is confirmed per listing. For 1 Sailwing Lane — a harbourfront residence positioned on two lots — Christopher Hughes can confirm exactly what conveys and the slip's usable length before you travel.

Windmill Harbour POA dues differ by property class, a one-time transfer fee applies at closing, and a 2026 special assessment has been enacted. Management moved to FirstService effective January 2026, so Christopher Hughes pulls the current figures for this property class directly rather than quoting a cached number.

Windmill Harbour is among the Hilton Head communities that restrict short-term rental, enforcing minimum lease terms by POA covenant — so this is a primary or second-home purchase, not a rental-income play. The Town of Hilton Head separately regulates any rental under 30 days island-wide.

The South Carolina Yacht Club sits within the harbour but is a distinct entity from the POA, with its own membership — it is not conveyed with a home purchase. The club offers tennis courts, a pool, sauna, bar and restaurant.

Both have private locked harbours — two of the three on the East Coast are on this island. Windmill Harbour's case is its measured specifics: a constant eight-foot basin depth, a 75 ft × 19 ft chamber, dockage to 70 ft LOA, 24-hour keycard lockage, and the South Carolina Yacht Club inside the gate.

The harbour sits directly on the Intracoastal Waterway at mile marker 558, about a half mile south of the Pinckney Island Bridge near channel marker 27 in Calibogue Sound. The lock is a genuine second entrance to the community straight from the ICW.

1 Sailwing Lane is a harbourfront residence with harbor views across 3,589 square feet, offered at $2,250,000. The rear porch and deck are oriented to the water, and the home is positioned on two lots within the gated community.

Hilton Head's $1M+ segment is balanced and firming — closed volume rose 12.0% through the first half on inventory down 15.3% — and sellers here land near ask at about 96.4% of list. A harbourfront home on two lots with deepwater lock access is a scarce asset at this scale.

Yes — the primary suite is on the main level, with a fireplace and a spa-inspired bath featuring a large soaking tub. The home is 3 bedrooms and 4 baths across 3,589 square feet with soaring ceilings.

The community is gated with guard service and offers a pool and a dog park, surrounded by marshland and tidal waterways near the north end of the island. The Cross Island Parkway is a short drive, connecting to the island's dining, shopping and golf corridors as well as the mainland.
