Choosing marina berths for superyachts

Why berth selection deserves a framework

A superyacht berth is not a commodity. It is a operational decision that affects crew logistics, guest experience, maintenance windows, insurance compliance, and asset preservation. The right berth reduces transit time to cruising grounds, provides reliable technical infrastructure, and offers a security posture aligned with the vessel's profile. The wrong one creates daily friction.

This guide structures the evaluation criteria used by experienced captains and yacht managers when comparing marinas for yachts 40 m and above.

Core technical criteria

Berth dimensions and approach

• Length overall (LOA) clearance: Minimum 1.15 × yacht LOA for safe manoeuvring; 1.3 × preferred for beamy displacement hulls.
• Beam clearance: Fairway and finger width must accommodate beam + 2 m minimum for fendering and crew movement.
• Draft at LAT (Lowest Astronomical Tide): Verify charted depth minus safety margin (1 m minimum) exceeds yacht's max draft. Request recent hydrographic survey data.
• Air draft: Bridge clearances on approach channels — critical for masts, radar arches, and tender cranes.

Power and utilities

• Shore power capacity: 16 A / 32 A / 63 A / 125 A / 250 A three-phase availability. Confirm actual delivered voltage under load (voltage drop on long runs is common).
• Redundancy: Dual independent feeds, backup generator capacity on the marina grid.
• Water: Potable water flow rate (L/min) and pressure at the berth. Watermaker relief is a operational cost saving.
• Data: Fibre or dedicated 4G/5G with SLA. Crew and guest expectations now exceed basic WiFi.

Waste and environmental

• Grey/black water pump-out: fixed pipeline at berth or mobile truck frequency.
• Bilge/oily water reception facilities (MARPOL Annex I compliance).
• Recycling and hazardous waste streams (filters, batteries, paint residues).

Operational and service criteria

Security

• ISPS certification level (required for yachts > 500 GT or carrying 12+ passengers).
• 24/7 guard presence, CCTV coverage, access control (biometric / keycard / ANPR).
• Dedicated superyacht zone with separate perimeter vs. mixed-use marina.

Concierge and technical support

• On-site or preferred shipyard with travel lift capacity for the yacht's displacement.
• Provisioning: bonded stores, fresh provision delivery to berth, fuel barge access (road vs. barge delivery affects cost and speed).
• Crew facilities: gym, laundry, lounge, shuttle service, accommodation for rotating crew.

Seasonal access and events

• Year-round vs. seasonal (Med: typically April–October; Caribbean: November–April).
• Event congestion: Monaco Yacht Show, Cannes Yachting Festival, F1 Grand Prix, Voiles de Saint-Tropez — berths book 12–18 months ahead; rates multiply 3–10×.
• Hurricane/cyclone season policy: haul-out obligations, insurance waivers, relocation contracts.

Location strategy

Home port vs. seasonal base

A home port optimises for crew stability, shipyard relationship, flag state survey access, and owner proximity. A seasonal base optimises for cruising ground access, event calendar, and guest logistics. They are rarely the same marina.

Cruising ground reach

From a Mediterranean base, evaluate day-trip and overnight radius: Monaco reaches Cap Ferrat, Cannes, Sanremo; Porto Cervo reaches Bonifacio, La Maddalena, Costa Smeralda anchorages. Fuel range at displacement speed vs. planing tender transfers changes the calculus.

Financial and contractual

• Annual vs. seasonal vs. transient rates: Annual contracts often include 2–3 months "free" but lock capital. Transient daily rates at top Med marinas: €500–2,500+/day for 40–60 m.
• Indexation clauses: CPI-linked, fixed uplift %, or "market review" — the last creates uncertainty.
• Subletting rights: Can the owner charter the berth during absence? Many marinas prohibit or take 30–50 % commission.
• Insurance requirements: Marina may require specific P&I club, wreck removal coverage, environmental liability limits.
