Diving Flanked Wreck (Pula)
Site Overview
Flanked Wreck (Pula) is a wreck dive site in Istria (West Coast), Croatia, set in the clear, fish-rich waters of the Adriatic Sea. The Flanked is a 50 m Austro-Hungarian torpedo boat resting at 18-25 m just outside Pula, a compact and coral-encrusted wreck dive close to the city. The small hull is draped in sponges and gorgonians and attracts scorpionfish, moray eels and a steady stream of reef fish. Its shallowish depth makes it one of the more accessible wrecks in the Pula area for sport divers. The surrounding reef continues the dive after you have circumnavigated the wreck, with good macro potential in the cracks. Visibility is generally excellent, and the short boat ride makes it an easy addition to a training or fun day. It pairs well with Pula’s other wrecks and the shallow training bays for a varied itinerary. Conditions are typical of the Croatian coast: visibility generally runs from 15 to 30 metres, the current is low and the water temperature ranges between 14 and 25 degrees Celsius depending on season and depth. The marine life is classic Adriatic, centred on small red scorpionfish, mediterranean moray, two-banded seabream, with the full community described below for those planning a dive. Because of its intermediate rating and the need for Advanced Open Water certification, Flanked Wreck (Pula) is best approached with the right thermal protection and, where relevant, wreck or deep training. It is a representative example of why Croatian diving, with its wrecks, walls, caves and gorgonian forests, attracts divers who want history and Mediterranean life in equal measure.
Dive Briefing
"Entry is made by boat, with a transfer of about 15 minutes near Pula, and divers should check in with a local centre before entering the water. The Flanked is a 50 m Austro-Hungarian torpedo boat resting at 18-25 m just outside Pula, a compact and coral-encrusted wreck dive close to the city. The small hull is draped in sponges and gorgonians and attracts scorpionfish, moray eels and a steady stream of reef fish. Its shallowish depth makes it one of the more accessible wrecks in the Pula area for sport divers. The surrounding reef continues the dive after you have circumnavigated the wreck, with good macro potential in the cracks. Plan your profile around a maximum depth of 25 m and an average of 20 m, keeping a close eye on gas and, in deeper sections, on the cold thermocline. Buoyancy control matters: silty or vegetated bottoms and submerged structures are easily disturbed, and depth to 25 m requiring gas awareness is a real consideration here. Take a moment to review the site-specific hazards with your guide, because conditions at Flanked Wreck (Pula) can shift quickly with wind and tide and change the feel of the dive. A safe ascent with a surface marker buoy and a clear exit plan completes the dive, with emergency cover routed through Pula Hospital Hyperbaric Chamber."

Traveler Notes
Who is this for?
Flanked Wreck (Pula) suits intermediate divers holding at least an Advanced Open Water certification, and it is a strong choice for those who enjoy the clear, fish-rich water of the Croatian Adriatic. Photographers, training groups and divers chasing wrecks, walls, caves or macro life will all find something here, provided they respect the temperature, the marine park rules and the limits of each site. It is less suitable for absolute novices unless booked through a centre running a supervised course, and the deepest or most enclosed sections should only be attempted with the correct specialist training and a guide. Planning a dive here with a licensed Croatian operator not only keeps you safe but also helps protect the fragile gorgonian forests, seagrass and wrecks that make the site special.
