Dive Site Overview

What sets Halftime Dive Boat apart is its direct access to Long Island's 'Wreck Valley,' a remarkable collection of over 200 historical shipwrecks. This 40-foot Downeaster, operated by experienced divers, transports enthusiasts to an array of sites spanning centuries of maritime history in the North-western Atlantic Ocean.

From shallower inshore wrecks like the Iberia and Lizzie D, found at depths between 18-24 m (60-80 ft), to formidable offshore giants such as the USS San Diego at 33 m (110 ft) and the SS Oregon at 43 m (140 ft), the boat serves a broad spectrum of certified wreck divers. For the technical community, the vessel can reach sites like the U851 at 46 m (150 fsw) and even the SS Andrea Doria resting at 82 m (270 fsw), though these require highly specialized training and equipment. The Halftime embarks from the Shinnecock Inlet, exploring both artificial reefs, including subway cars and deconstructed bridge spans, and natural reef formations.

This region offers more than just shipwrecks; it's also a gateway to observing pelagic life, providing a dynamic and historically rich dive experience for those exploring New York's saltwater domain. Divers should come prepared for ocean conditions typical of the Atlantic seaboard.

Best Time to Dive

Examining the predictable patterns of the Atlantic climate helps divers pinpoint optimal times for expeditions with Halftime Dive Boat. The peak dive season generally runs from June through October, aligning with the 'Good' dive scores reported during these months. Air temperatures are most comfortable from June to September, averaging between 20-25°C (68-77°F), which lessens surface chill before and after dives. During this period, average wave heights are typically lower, often around 1.0-1.3 m (3-4 ft), contributing to calmer boat rides and easier entries/exits. Rainfall remains relatively low across these months, ranging from approximately 2.2-4.0 mm, generally not impacting dive plans significantly. Conversely, winter months, particularly January, March, and December, receive 'Moderate' dive scores. Air temperatures drop dramatically, approaching 0°C (32°F) in January and February, and wave heights frequently exceed 1.5 m (5 ft), making for more challenging conditions and colder surface intervals. Despite colder conditions, some diving persists in these shoulder seasons for those adequately prepared for the Atlantic's vigor.

Dive Experience & Conditions

The prevailing current dynamics around Long Island's offshore and inshore wrecks can vary substantially. Divers should anticipate moderate to strong currents, especially at deeper or more exposed sites, which can enhance drift or challenge navigation around structures. Visibility is variable, influenced by localized weather patterns, plankton blooms, and tidal movements; it's not uncommon to experience clear days followed by periods of reduced sight. Water temperatures aren't consistently reported, though they typically align with seasonal Atlantic norms, cooling significantly in winter and warming during summer months. This means a drysuit or substantial wetsuit is essential for comfort and safety outside of peak summer. Most dives are conducted as boat entries, requiring divers to be proficient with open ocean procedures and comfortable with potential surface chop. The experience caters predominantly to Advanced Open Water certified divers and above, reflecting the challenging nature of wreck diving in dynamic Atlantic waters.

Dive Difficulty & Safety Guidelines

To ensure a safe and responsible dive experience with Halftime Dive Boat, divers should adhere to specific operational guidelines. A minimum Advanced Open Water (AOW) certification is strictly required, with deep or higher certifications recommended for many sites. Furthermore, divers must have at least 20 logged dives, demonstrating foundational experience, and provide proof of prior East Coast diving unless under direct instructor supervision for training. Every diver is expected to carry essential safety equipment, including two cutting tools, a DSMB (Delayed Surface Marker Buoy) with a spool, a primary light, and a backup light. A wreck reel and a JON LINE are highly recommended, particularly for penetrations or navigating complex structures. Completing the mandatory release and liability forms before boarding is a prerequisite for all participants, emphasizing personal accountability in these demanding environments.

Marine Life at Halftime Dive Boat

Upon descending onto Long Island's wrecks and reefs, divers are often greeted by the inhabitants drawn to these artificial structures. Sightings can include various species of pelagic sharks, particularly during specific seasons when they frequent the offshore feeding grounds. Whales and dolphins are also observed, especially from the boat during surface intervals, adding a significant topside component to the wildlife encounter.
