How to Choose an Overnight Marina: 8 Questions to Ask Before You Book

The best marina in a harbour is rarely the one with the biggest sign. It is the one whose water is deep enough at your berth, whose pontoon fits your beam, whose power pedestal matches the plug on the end of your shore cable, and whose gate you can walk through at eleven at night without worrying about the outboard. A transient slip is a small purchase with an outsized effect on how the next day goes. Five minutes of questions before you reserve saves a night of fenders, extension cables and cold dinners. These are the eight worth asking.

How much water is under the keel at the berth itself?

Marinas quote entrance depth, which is not the number you need. Ask for the depth at the specific berth they intend to give you, at lowest astronomical tide, and ask when it was last surveyed or dredged. A harbour that reads three metres at the entrance can shoal to two along the inside of a breakwater, and silt moves with every winter storm.

If you draw 1.8 metres, a two-metre berth is not comfortable on a falling tide with swell running. Ask about the bottom, too: soft mud is forgiving, rock and coral are not. And ask whether your berth sits in a fairway where every passing motorboat sends wash rolling under the hull, or whether it is tucked behind a wall.

Will the boat actually fit the berth?

Length is the easy part. Beam and overhangs cause the trouble. On a finger pontoon the gap between the fingers is fixed, and a 3.5-metre beam will not squeeze into a 3.2-metre slot no matter what the booking page suggests. Bowsprits, davits, boarding ladders, outboard brackets and a folded bimini all add centimetres you have not counted.

Ask for the beam of the berth, not just the length, and ask how you are expected to lie: alongside, bows-to with a lazy line, stern-to with your own anchor, or in a box with two mooring lines. Mediterranean marinas often expect a stern-to approach, which changes your fender plan completely. If you are not confident handling the boat in a tight fairway with a crosswind, say so when you book. A good harbour office will give you a wider berth or send someone to take your lines.

What does the power and water supply really deliver?

"Electricity included" can mean anything from a 16-amp socket on a shared pedestal to a metered 63-amp supply with a card you top up at the office. Check the amperage, the voltage and the shape of the socket before you arrive.

• Amps and voltage: 16A, 32A or 63A; 230V single phase in much of Europe, 30A or 50A in North America. Bring the right adapter and a spare.
• Metering: is power flat-rate, billed per kilowatt-hour, or sold as a daily card?
• Breakers: ask whether the pedestal trips when a kettle and a heater run together, and who resets it at seven in the morning.
• Water: is it potable, and is there a tap on your own pontoon or one hose bib shared by six berths?
• Generator and quiet hours: many marinas ban generators overnight; some ban them entirely.

Who is on site after dark?

Ask whether the marina is staffed around the clock, whether the gates are locked at night, and how you get the code. Lighting and CCTV on the pontoons matter more than a smart office. A liveaboard community is often the best security a marina has: someone notices a stranger walking the dock at two in the morning.

Find out where you leave a dinghy or tender, and whether the dinghy dock is lit. If you plan to leave the boat for a few days, ask whether anyone checks lines and fenders in a blow, and whether you should double up. Get a phone number for the night watch or harbourmaster and save it before you go ashore.

How do you get to town, and back?

A marina two kilometres from the nearest shop is fine if you have bikes and a problem if you do not. Ask about the walk, the bus, the ferry timetable, and whether taxis or ride-hailing genuinely serve the area after the last ferry. If you plan dinner ashore, check the last return service before you commit.

Ask about the fuel dock, pump-out station, chandlery and laundry, and whether there is somewhere within walking distance to eat on the night you arrive too tired to cook. If you may need a mechanic, ask now rather than at five o'clock on a Sunday.

What does the rate include, and what can be cancelled?

Ask for the total, not the nightly headline: visitor taxes, environmental levies, liveaboard surcharges, shower tokens, laundry, and any charge for a second line ashore. Confirm arrival and departure times, because many marinas count a night from noon to noon and an early arrival can cost you an extra day. Ask what happens if weather delays you, and what the cancellation terms are. Get the berth number, the rate and the conditions in writing by email; a screenshot of a booking page is not a contract.

What happens if the weather turns or you arrive late?

Ask whether the berth is guaranteed or assigned on arrival, and what the fallback is if someone is already in it. Ask how the approach behaves in a strong onshore wind and whether the harbour is safe to enter at night. Ask who takes your lines, and what time the office closes. Arriving at ten in the evening to a locked gate and no code is a common, avoidable misery. Keep a second option in your notes: an anchorage outside, or a neighbouring marina whose number you have already called.

Before You Book: The Eight Questions

1. What is the depth at the berth at low water, and when was it last surveyed or dredged?
2. What is the beam of the berth, and how are you expected to tie up?
3. What amperage and voltage does the pedestal supply, and is power metered?
4. Who is on site overnight, and how do you get through the gate after hours?
5. How do you reach shops, transport and fuel from the pontoons?
6. What is the total cost, including taxes and extras, and what are the cancellation terms?
7. What time does the office close, and who takes your lines?
8. What is your alternative if the berth is double-booked or the weather keeps you out?

Ask them on the phone, write the answers down, and confirm the important ones by email. Then top up the water, check the fenders, and go and enjoy the evening ashore.
