Scuba diving at Two Brothers' Shipwreck in Alonissos

Two Brothers' Shipwreck

About This Site
The Two Brothers' Shipwreck is a resident modern wreck lying in the sheltered channel between the two Adelfoi ("Two Brothers") islets, roughly 5.8 nautical miles east-southeast of Patitiri inside the National Marine Park of Alonissos. It is a wooden immigration boat, a traditional caique, that sank here around two decades ago and now rests intact on a sandy bottom at about 22 m, with the hull explorable down to roughly 30 m. Divers drop onto a sandy channel and finger through seaweed until the wooden hull appears out of the blue, circle and work the wreck, then follow the strewn wreckage and debris field back up toward the coastline. It is a distinct site from the neighbouring Two Brothers wall dive: where that dive is a vertical reef and cliff experience, this is a self-contained wreck dive on a benign, sheltered bottom, making it a favourite intermediate-to-advanced wreck outing in the marine park.

The wreck lies in the channel between the two Adelfoi islets, tucked against the northern headland of the larger southern island, so the bulk of that island shields the site from the west, southwest and south. The open window is to the east and southeast, where the strait mouth faces the open Aegean — the E-ESE-SE sector is the most exposed and carries any easterly or southeasterly wind-sea. The dominant summer hazard is the Meltemi from the north to northwest: although the northern islet and the strait geometry give partial shelter, N-NE wind funnels down the channel and can build surface chop and current at the exposed mouth, which is the usual reason a trip out to the Adelfoi is postponed. There is no true ocean groundswell in this enclosed Aegean setting — waves here are locally wind-generated over fetch.
