Why dive here
With 46+ marine species recorded in the area - including dolphins, sea turtles and cuttlefish - HM MTB 655 offers some of Istria Peninsula's richest wreck diving. Water ranges 12-26°C, warmest July, August, September.
The HM MTB 655 isn’t your average Croatian wreck. This torpedo boat, sunk in 1945, rests upright at 49m, making it a serious technical dive. What we love about her is the immediate sense of history; you can almost hear the rumble of her engines. Descending through the blue, the wreck materialises slowly, her lines still sleek despite the passage of time. At 33.5m long, she’s a compact but incredibly atmospheric dive. We typically start our exploration around the bow, where the damage from the mine strike is still evident. From there, we work our way along the deck, peering into the open hatches that hint at the machinery below. Shoals of small fish, usually silversides or juvenile sea bream, flicker around the superstructure, and we’ve often spotted lobsters tucked into crevices. The visibility here can be spectacular, sometimes stretching to 30m, which really allows you to appreciate the scale of the wreck as you circle her. Our favourite spot is usually the stern, where the twin propellers are still perfectly intact, a testament to the build quality. She’s definitely one for advanced wreck enthusiasts comfortable with deeper profiles and decompression. Go early to avoid any boat traffic, the surface can get busy.
