Setting & Character
Beaucette is small, sheltered and rural, enclosed by rock walls, with a restaurant on site and L'Ancresse Bay nearby. It feels a world away from St Peter Port, though town is only a bus or taxi ride away.
Arrival by Sea
The marina publishes approach notes from the north (from east of the Platte Fougère light tower) and from the south (from west of the Roustel light tower), both leading to its approach waypoint south-east of the Petite Canupé south cardinal, then west along the Beaucette fairway. Follow the white entrance markers and leading lights through the narrow cut. Use those notes with current charts and the Little Russel tidal streams; a waypoint is never a substitute for a chart.
Call 'Beaucette Marina' on Channel 80 before entering, to make sure no boat is coming out. A marina dory can meet you and guide you in. If you are early on the tide, wait on one of the four waiting buoys north of the fairway.
Beaucette is an approved port of entry: fly the Q flag, complete GC27 and post it in the yellow Customs box outside the marina office. Leaving Great Britain for the Channel Islands counts as leaving the UK for customs purposes, so submit a pleasure craft report to Border Force and HMRC before you sail. Coming home, report again, fly the yellow Q flag from the 12-mile limit until you have finished reporting, and declare anything over your allowances.
Berthing Experience
The marina has 115 permanent and up to 45 visitor berths, and recommends booking ahead because visitor berths fill quickly. Inside the entrance, turn to port; the visitors' pontoon is ahead. Cleats are cow-horn and the pontoons and walkways are lit. The marina says it takes yachts and motor cruisers up to 60 feet.
Facilities Afloat
The marina lists shower blocks, free Wi-Fi for visitors and Camping Gaz 907 bottles from the office. Check electricity, water and fuel arrangements when you book.
Marine Services
Beaucette is a marina rather than a boatyard. For fuel, Guernsey Ports lists the leisure fuel pontoon in St Sampson's Harbour and the fuel berths in St Peter Port; confirm hours and tides before you go.
Ashore
The Saltwater Restaurant & Bar is on site; the marina lists meals from 11am, Wednesday to Sunday, closed on Mondays and Tuesdays, so check before you rely on it. Coastal walks lead to Fort Doyle, the Déhus Dolmen and the beach at L'Ancresse Bay, and the marina has bikes for hire.
Best For
Arrivals direct from the UK or France who want to clear in quietly; boats staying a few days; crews who prefer a sheltered basin to a town harbour.
Less Suitable For
Arrivals near low water; boats over about 60 feet; entering the narrow cut in strong onshore winds.
History & Local Character
The basin was a quarry before it was a marina, and the marina says the entrance was blasted through solid granite by the Royal Engineers. It is one of the more unusual marinas in the Channel.
Nearby Cruising
St Peter Port is round the corner to the south, with Herm and Sark across the Little Russel. Alderney is to the north-east.
Skipper's Notes
Arrive within three hours of high water with 2 metres over the sill, checking the gauge on the small breakwater. Call 'Beaucette Marina' on Ch 80 before entering, turn to port inside, and post your GC27 in the yellow box by the office. Use the waiting buoys if you're early.
Old Sea Dogs View
Beaucette is the back door into Guernsey: clear in, tie up and have lunch while St Peter Port is still waiting for the sill.
