Istanbul & the Bosphorus

Istanbul is the one place on earth a yacht can cross from Europe to Asia under her own power, and do it twice before lunch. The Bosphorus runs seventeen nautical miles between the Black Sea and the Sea of Marmara, narrowing to just 700 metres between Anadoluhisarı and Rumelihisarı, Ottoman fortresses of 1394 and 1452 that still face each other across the current — and the current is the point: this is a working strait, not a cruising ground, with no anchor down anywhere in the fairway. The fleet bases instead at marinas on the calm Marmara shore either side of the old city, and treats the crossing itself, past Dolmabahçe Palace and mile upon mile of timber waterfront mansions, as the destination.

“No anchor goes down in the Bosphorus itself — on this water, the crossing is the destination.”

Signature anchorages

A working strait, not a chain of coves — the fleet's proper stops sit at either end of the crossing, out in the Sea of Marmara.

• The Bosphorus crossing — Europe to AsiaSeventeen nautical miles, Black Sea to Marmara, inside a mandatory two-way traffic separation scheme with a 10-knot speed limit and VHF reporting for larger vessels. No anchoring anywhere in the fairway — this is transited in a day, not moored in.
• Dolmabahçe Palace & the imperial waterfrontSultan Abdülmecid's 1856 palace and the run of nineteenth-century summer residences north toward Ortaköy, seen from the water only — the shipping lane runs close along this shore, so it's a slow pass, not a stop.
• The yalı reach — Bebek to KanlıcaTimber Ottoman waterfront mansions (yalı) line both shores; the oldest survivor is the 1699 Amcazade Hüseyin Pasha Yalısı at Kanlıca. Bebek's own small harbour stays packed with local moorings — better appreciated slow-and-underway than as a stop.
• Rumelihisarı & Anadoluhisarı — the Fortress NarrowsThe strait's narrowest point, 700m across, faced by fortresses raised in 1452 and 1394; also its deepest water, over 100m in places. The current and eddies here are exactly why nobody anchors mid-strait.
• The Golden Horn (Haliç)The old city's natural harbour, spanned by the Galata Bridge and backed by the Topkapı and Süleymaniye skyline. Shallow, ferry-thick and built-up along both banks — a tender or day-boat excursion from a Bosphorus-side berth, not a superyacht anchorage.
• Büyükada & Heybeliada, Princes IslandsGenuinely car-free — only municipal, naval and police vehicles, phaetons now replaced by electric runabouts — and no marina on either island, so this is proper ground-tackle work: off Büyükada's north coast, west of the ferry pier, in 3–5m over sand and weed; Heybeliada's Çam Limanı, on the south coast, is the only anchorage properly sheltered from the prevailing N/NE.
• Maiden's Tower, the strait's southern gateA 2,400-year-old islet tower off Üsküdar marking the Bosphorus's southern mouth, rebuilt by Mehmed II after 1453 and now a café reached only by boat — the last landmark before the Sea of Marmara opens out.

The scene

Fifteen hundred years of skyline, and the one week a year the fleet itself is on show.

Table & stay ashore

Istanbul's Michelin table, a rooftop over the strait, and two hotels built into the palace row the fleet passes.
