Dive Site Overview

Simpson & Pantari introduces two distinct wrecks: the motor barge Simpson and the wooden koster Pantari. Simpson, an old motor barge that once transported ore from the Utö mine, sank in 1936 after misjudging the distance to a skerry.

No lives were lost in the incident. Its bow rests at a shallower 7 m (23 ft), while its stern descends to 20 m (66 ft) and sits atop an older, unspecified wreck. The Simpson wreck measures 25 m (82 ft) long, 5 m (16 ft) high, and 7 m (23 ft) wide.

At the time of sinking, it carried 7 tons of cokes slag, 65 tons of macadam, and 1 ton of general cargo. Pantari, a wooden koster, sank earlier in 1924 after grounding on Slottgrynnan in Nämndöfjärden, now lying at a maximum depth of 24 m (79 ft).

This koster offers a rewarding 'nature dive' experience, characterized by multiple ledges and intriguing natural formations at various depths. Both sites are accessible via boat entry, with the overall dive area reaching a maximum depth of 35 m (114 ft), catering to a range of recreational diving interests.

Dive Experience & Conditions

Beginning the descent at Simpson & Pantari, divers will encounter the bow of the Simpson motor barge at just 7 m (23 ft). From there, the wreck slopes gradually, leading down to the stern resting at 20 m (66 ft), which adds a dynamic profile to the dive. The nearby wooden koster Pantari is found at a consistent 24 m (79 ft) depth, offering a distinct experience with its surrounding natural ledges. Visibility in these brackish waters typically ranges from good to moderate, varying depending on recent weather and currents. Currents are generally mild, but conditions can fluctuate. Divers should anticipate cold water and plan accordingly; the use of drysuits and hoods is practically essential for comfort and safety. This site offers distinct wreck diving challenges alongside opportunities for macro marine life observation on the surrounding natural features.

Dive Difficulty & Safety Guidelines

Diving at Simpson & Pantari requires careful adherence to cold water and wreck diving safety protocols, as site-specific hazards aren't consistently reported beyond the wrecks themselves. Given the cold, brackish water, maintaining proper thermal protection, such as a drysuit and hood, is critical to prevent hypothermia. These wrecks, while at recreational depths, still demand advanced planning, especially for any potential penetration, which should only be attempted by appropriately certified and experienced wreck divers. Carrying a dive computer and a Surface Marker Buoy (SMB) is standard practice. Always check local conditions and follow guidance from your dive operator, ensuring an understanding of boat entry and exit procedures for a safe experience. Respect for the historical integrity of these sunken vessels is paramount; avoid disturbing any artifacts.
