Dive Site Overview
This dive site holds a history rooted in its past as a cluster of small boat jetties, where local fishers once found waters teeming with herring. Today, the area features a developed wooden terrace and a designated grill spot, serving as a practical base for divers to gear up and a tranquil vantage point for observing sailboats.
The main attraction, the Betty Blue wreck, is a 6-meter (20 ft) sailboat, reported abandoned in Haninge between 2013 and 2014, eventually sinking on its natural buoy. This vessel rests upright, still secured by its original line, and is now notably adorned with small blue mussels, creating a nascent ecosystem.
Diving here offers a maximum depth of around 25 m / 82 ft, primarily in brackish water, presenting a distinct exploration opportunity for those interested in local maritime history and the unique ecological adaptations found in such environments. The approach involves a straightforward shore entry followed by a short fin kick, making it accessible for a range of certified divers.
Best Time to Dive
Optimal diving conditions at Betty Blue span from March through September, when dive scores are consistently rated as 'Excellent'. During these months, average air temperatures range from 2.7°C (37°F) in March, gradually climbing to 17.6°C (63.7°F) in July, before settling around 14.6°C (58.3°F) in September. Rainfall is generally lower in this period, with monthly averages between 1.0 mm and 3.0 mm, reducing surface runoff and potentially improving visibility. Colder months, from October to February, still rate 'Good' for diving, but air temperatures can drop below freezing, averaging from 8.1°C (46.6°F) down to -1.9°C (28.6°F), necessitating appropriate cold-water gear.

Dive Experience & Conditions
The dive begins with a comfortable shore entry from the wooden terrace, transitioning into the brackish water that characterizes this coastal environment. Divers typically navigate along the 13-meter (43 ft) depth contour, a leisurely swim of about ten minutes, to precisely locate the Betty Blue wreck. This sailing boat rests neatly upright, still anchored by its original line, a sight often described as well-preserved and stable. Visibility in these brackish waters can vary, influenced by local conditions, seasonal runoff, and plankton blooms, so divers should be prepared for changing clarity. Depths at the site reach approximately 25 meters / 82 feet, offering a decent profile for recreational divers to thoroughly explore the wreck and its immediate surrounding ecosystem.
Dive Difficulty & Safety Guidelines
Diving in Sweden's cooler brackish waters necessitates specific considerations to ensure both safety and comfort. Always plan your dive according to your certification and experience level, especially given the potential for varied visibility and lower water temperatures. It's prudent to consult with local dive professionals before heading out; they can offer current insights into site conditions, including any temporary environmental changes. Given the potential for colder water, proper thermal protection, such as a drysuit or thick wetsuit, is crucial to prevent hypothermia during extended bottom times. Always dive with a buddy, and carry appropriate navigation tools for underwater orientation. Additionally, be mindful of boat traffic, especially near the surface, as the area is frequented by sailboats.
