Dive Site Location & Key Facts
Everything you need to know about this dive site.
Dive Site Overview
The Bodekull, a 17th-century Swedish naval vessel, represents a profound wreck diving experience near Dalarö, southeast of Stockholm. Sunk in October 1678 while transporting flour, this 20-meter / 66-foot ship settled upright and remains remarkably intact.
Divers encounter a true maritime time capsule; two of its three masts still stand in their original positions, a striking sight for a vessel of this era, providing a tangible link to seafaring history. Low salinity in the Baltic plays a crucial role in its exceptional preservation, effectively deterring shipworms that typically devastate wooden wrecks. This natural protection has allowed for centuries of stability.
Relics and artifacts continue to be discovered during archaeological surveys, providing continuous scientific interest and shedding light on 17th-century maritime life. Resting at a maximum depth of 33 meters / 108 feet, the site is considered an advanced deep dive, requiring appropriate training and experience.
Previously known as the Dalarö wreck until its identification in 2017, the vessel lies close to Edesön and is clearly marked by a yellow buoy, signifying its protected status as a marine cultural reserve.

Recorded air temperatures in May and June average around 11-16°C / 52-61°F, often accompanied by lower average rainfall, enhancing surface comfort for preparations and boat travel. While specific water temperature data isn't consistently reported for this site, these months generally provide the most pleasant above-water experience. Wave heights are lower during these times, contributing to calmer water entries and exits. Dive scores remain 'Good' year-round, but 'Excellent' scores in May and June suggest a slight edge in overall conditions. Expect some rainfall throughout the year; July shows slightly higher averages at 3.2mm.

Dive Experience & Conditions
Accessing the Bodekull wreck invariably requires a boat entry, as it lies offshore near Edesön, marked by its protective buoy. Divers planning an expedition here should be prepared for typical Baltic Sea conditions, characterized by brackish water. Unique low salinity is paramount to the wreck's exceptional preservation, though it means divers experience different buoyancy characteristics compared to freshwater or full saltwater. Specific water temperature averages for the site are not consistently reported, but conditions over 30 meters down are generally cool to cold, necessitating appropriate thermal protection. Currents are not always strong but can vary based on local weather and tidal influences. Moderate visibility is common, which, combined with the advanced depth, makes effective torch use essential for appreciating the ship's intricate details and navigating its structure.
Dive Difficulty & Safety Guidelines
Ongoing plundering poses a primary concern for the Bodekull wreck, a widespread issue affecting historic wrecks across the Baltic Sea. Designated a Marine Cultural Reserve, the site features explicit signage warning against interference. Despite protected status, items have previously been removed, disturbed, or damaged, including parts of a pistol frame. Sweden's coastguard actively monitors the wreck, and local residents are alerted to report suspicious activities. It's crucial for all divers to respect its historical significance and legal protection. Any removal or disturbance of artifacts is strictly illegal; responsible diving involves observation and photography only, ensuring preservation of this irreplaceable piece of history for future generations.
