Maritime Transit Operations

Long Island Sound & Bay Ferry Crossings

Bridgeport & Port Jeff Central Sound Route Normal Operations

Sound wave chop 1-2 ft. Active departures from Port Jefferson harbor.

Cross Sound Ferry Orient Point → New London Normal Operations

The Race swell 2-3 ft. Standard auto and passenger sailings.

Fire Island Ferries Bay Shore → Fire Island Off-Season Schedule

Great South Bay calm. Commuter departures on schedule.

Navigation Hazard Watch

Plum Gut & The Race Tidal Rips

Extreme tidal currents frequently exceed 5.5 knots across Plum Gut and The Race when the Long Island Sound drains into Block Island Sound, creating standing waves and steep overfalls during opposing winds.

Current Velocity: 3.8 knots (Ebb)
Wave Height in Rips: 4 – 6 ft Standing Waves
Wind vs Tide: Opposing (Steep Chop)
