On Kos's southern shore, in the busy marina town of Kardamena, a half-day behind the wheel of a Blue Water 170 rewrites the usual beach day. Launch from 28is Oktovriou, Kardamena 853 02, Greece, and in four hours you can skitter across Aegean blue to quiet coves, thermal springs and small islets that sit like weathered stones off Kos's coastline. The Blue Water 170 is 4.99 m long, 30 HP and, critically, falls below the Greek licensing threshold - so no skipper certificate is required. That ease of access makes this rental ideal for families, couples and first-time boaters.
Kos Watersports outfits each boat with a full safety kit (lifejackets, flares, extinguisher), a sun tent, GPS tracker, Bluetooth radio and a cooler box. Staff provide a short hands-on briefing so you can handle the controls confidently; professional skippers are available to drive for an extra fee if you prefer. Boats carry reserve fuel and a tracker so the team can assist quickly if conditions change, and groups of up to six fit comfortably.
Choose a western loop to visit Helona, Blue Beach, Polemi (Magic Beach), Lagada and the small Kastri islet by Agios Stefanos, or head east toward Kardamena Bay, Agia Eirini and the hot-water Therma beach when winds allow. Expect crystalline Aegean water, patches of Posidonia seagrass visible under clear seas, and shoreline that alternates between sandy bays and pebbled coves carved from limestone and older volcanic deposits common in the Dodecanese. Therma's warm springs are a rare natural draw - bring a swimsuit and sense of curiosity.
Practical notes: fuel is not included - plan on roughly €30–€50 for a four-hour outing, depending on passenger load and sea state. Bring water, snacks, waterproof bags for electronics and a passport or photo ID for the captain. Snorkel gear is extra (€5 per mask) and ice for the cooler is not supplied.
This is more than a rental: it's a compact, self-led sea tour of Kos from the perspective of a small motorboat. For travelers based in Kardamena, it compresses exploration and relaxation into a single, sunlit half day. If you want a hands-on Aegean experience without the learning curve of larger craft—or the expense of a skippered charter—this Blue Water 170 rental is a practical, memorable way to see the Island of Hippocrates from the water.
Book online in advance for July and August to secure a morning slot when winds are gentler and water clarity is at its best; afternoons can be breezy. The check-in at 28is Oktovriou requires arriving 30 minutes early for instruction and safety briefing. Whether you pilot or request a skipper, this half-day rental delivers close-up views of Kos coastline, hidden coves and warm spring spots larger boats cannot reach.
