Explorer yachts are purpose-built for the kind of itinerary that a conventional motor or sailing charter cannot manage: multi-day passages to remote anchorages, open-water crossings in variable conditions, and complete independence from marina infrastructure. From Nafplion, the Argolic Gulf gives way quickly to open Peloponnese coastline, and the explorer vessels available in Greek waters and accessible from here open up a southern Greece that most visitors never see. Vessels from 40 to 65 metres carry a full tender garage, dive platform, watermaker, fuel for ten to fourteen days of range, and a crew of six to fourteen experienced in extended coastal and offshore passages. Stabilisers operate at anchor and underway; the hull and systems are built to handle conditions that would concern a conventional yacht. Weekly rates start at approximately 100,000 euros for a 40-metre explorer and reach 350,000 euros for the largest vessels. The advance provisioning allowance, approximately 30 percent, covers fuel, provisioning, dive equipment and any port fees along the route. Explorer charters from Nafplion work best over ten to fourteen days: the first section covers the Argolic Gulf and the Saronic islands, the second pushes south and west around the Mani peninsula, and the final section climbs the Ionian coast through the island chain northward.
