Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
Once a bustling liveaboard, the Harruby Wreck now rests upright on the sandy bottom of Ko Racha Yai's Bay 1, transformed into a thriving artificial reef. She was intentionally sunk on May 19, 2011, providing an accessible and engaging dive site for a wide range of certified divers.
Uppermost sections of the ship reach a comfortable 14 m (46 ft), with its base settling at approximately 20 m (65 ft). Such a depth profile allows for extended bottom times and a relaxed exploration pace. Harruby itself offers multiple easy swim-throughs; its structure is widely open, making it an ideal location for divers to practice or develop wreck penetration skills.
Adjacent to the main wreck, a field of artificial reef concrete cubes extends the dive, attracting diverse marine life and adding complexity to the navigation.
Furthermore, a short distance away lies the distinct wreckage of a smaller Thai fishing vessel, essentially creating a 'double wreck' experience. Combining these elements provides sufficient points of interest to fill an entire dive, ensuring varied exploration beyond just the main structure. It's a purposeful addition to the underwater landscape, fostering marine growth.

Best Time to Dive
Prime diving season for the Harruby Wreck typically aligns with Thailand's dry season, running from January through May and extending into October through December. During these months, conditions are generally favorable, air temperatures averaging a comfortable 27.5-29°C (82-84°F). Rainfall is minimal, often less than 5 mm, contributing to calmer seas and better visibility. Such a period often sees 'Good' dive scores, indicating optimal conditions for exploring the wreck and its surrounding artificial reef. In contrast, the months from June to September are marked by slightly more variable weather, reflecting a 'Moderate' dive score rating. While air temperatures remain warm, hovering between 28-29°C (82-84°F), increased rainfall, often ranging from 6-10 mm, characterizes this period. Higher wave heights, occasionally reaching over 1.0 meter (3.3 feet), can result, potentially affecting boat travel and surface conditions. Despite this, diving remains possible, though divers should expect potentially choppier seas and variable underwater clarity. Most operators continue daily trips during these months, adjusting schedules based on localized conditions.

Dive Experience & Conditions
Descending onto the Harruby Wreck, divers immediately notice its upright and largely intact structure, sitting peacefully on the sandy seabed. The water typically feels bath-like, with temperatures in the 27-30°C (81-86°F) range, making extended bottom times comfortable even without thick exposure suits. Visibility varies but is often clear enough to appreciate the wreck's full 26 m (85 ft) length and 5 m (16 ft) width as you approach. Mild currents are generally reported at this site, making for an easy drift around the wreck rather than a demanding swim. The simplicity of its open sections invites exploration, with natural light often penetrating deep inside, easing any apprehension about entry. Exploring the surrounding artificial cubes and the smaller fishing boat's remnants feels like an extension of the main dive, adding layers to the underwater landscape. It's a site that allows divers to relax and observe marine life interactions with the structure without battling strong forces, fostering a calm, engaging experience.
Dive Difficulty & Safety Guidelines
While the Harruby Wreck is considered accessible for many certified divers, approaching any overhead environment requires adherence to specific safety protocols. Its depth, reaching 20 m (65 ft) at the bottom, falls well within recreational limits, but careful air management is always key. The wreck offers easy swim-throughs, yet respecting the structure's integrity and avoiding contact with potential sharp edges or unstable sections is essential. Divers should maintain neutral buoyancy to prevent disturbing sediment, which can significantly reduce visibility for themselves and others. For those interested in exploring inside the wreck or tackling the 'full penetration' mentioned, obtaining a PADI Wreck Diver Specialty certification is highly recommended. This training provides critical skills in line usage, navigation, and emergency procedures specific to wreck environments. Always dive with a reliable buddy and ensure you're equipped with appropriate gear for the conditions, including a dive computer and surface marker buoy.
