The 7 Anchoring Mistakes That Put Sailboats On The Beach

Summary

The video argues that sailboats are often driven ashore not by the storm alone, but by anchoring decisions made earlier—when the water is calm and the crew thinks the boat is secure.

On August 18, 2022, a summer storm struck Corsica. Although the forecast called for winds of 20–30 knots, powerful gusts arrived within minutes. By the end of the day, rescuers had counted 48 boats on beaches. The narrator presents seven common anchoring mistakes that can turn a worsening forecast into a grounding.

Seven common anchoring mistakes

1. Letting out too little chain (scope). A short scope pulls upward on the anchor, making it easier to dislodge. The video recommends at least 5:1, with more for overnight stays or bad weather. Depth calculations should include the height of the bow roller and any expected rise in tide.

The video recounts the 2023 grounding and total loss of the cargo vessel Bonnie G. The captain put out 135 feet of chain, believing the water was 23–26 feet deep, but it was actually 68 feet—about a 2:1 scope. The narrator also advises marking the chain and moving elsewhere if a crowded anchorage leaves no room to let out adequate scope.

1. Relying on chain weight to absorb gusts. The chain’s catenary can cushion loads in moderate wind, but at around 50 knots it may straighten, leaving little shock absorption. Wind load rises sharply with wind speed, while the chain’s weight stays the same. Heavy chain still has benefits, but it should not be treated as a storm shock absorber.

2. Anchoring without a snubber. A stretchy nylon snubber transfers the load from the chain and windlass and softens sudden pulls. Tests cited in the video recorded snatching loads of about 600 pounds on an all-chain rode.

During a February 2010 squall at La Cruz, Mexico, one boat’s snubber broke. Another boat’s rode parted, and it was thrown onto the beach, though a wave later lifted it back off. The narrator recommends using a snubber every night, protecting it from chafe, and keeping a spare ready.

1. Using an anchor unsuited to the seabed. Anchor performance can change dramatically between sand, mud, weed, rock, and thin sand over rock. A 2006 West Marine test in firm sand favored newer-generation anchors, while a 2008 Practical Sailor test found that some of those anchors struggled on rock and steep slopes. Weed can also prevent an anchor from reaching the bottom beneath it.

The video recommends checking charts and pilot books and, where possible, inspecting the anchor after setting it. In one storm near Colonia Sant Jordi, Majorca, the boat Dreamtime held through winds that rose from about 30 to 70 knots, but its snubber hook was bent nearly 90 degrees. The crew later found thin sand over solid rock beneath the anchor.

1. Anchoring for the wind at hand, not the wind expected. In Girolata, Corsica, a 43-foot Outremer catamaran named Gagu was anchored in deep sand with offshore wind. The wind then swung onshore and drove the boat toward the beach. The catamaran flipped before the chain came tight; its crew drifted for about 15 minutes and reached shore alive. Seven boats went ashore in the bay, and none remained anchored.

The narrator’s key question is: If the wind went right around tonight, where would the boat end up? If the answer is the beach, rocks, or another boat, the anchorage or escape plan needs to change. The video also notes that some conditions—such as Hurricane Beryl’s Category 5 impact on Carriacou on July 1, 2024—are beyond what anchoring technique can safely manage.

1. Trusting weak links in the ground tackle. Swivels, shackles, pins, and worn chain can fail before the anchor does. Tests cited in the video found that certain 5/16-inch swivels failed at 7,500 pounds, below the 9,000-pound rating of the matching chain.

The narrator recommends checking and securing shackles, replacing worn or rusty components, reconsidering whether a swivel is necessary, and tying the bitter end of the chain to a strong point in the boat.

1. Leaving the boat unattended—or sleeping through deteriorating weather. A dragging boat can endanger other vessels and rescuers, not just its owner. The video describes several groundings, including Norma Jean on East Beach in Santa Barbara on January 4, 2023, and the 77-foot Angelique, which went ashore on Dockweiler Beach in February 2014 after its owner reportedly fell asleep as it dragged. Removal cost $227,500, paid by public agencies.

In Avalon, Catalina Island, on December 30, 2014, a storm drove at least four boats ashore and two men died—one a liveaboard and one a harbor patrol officer trying to rescue boats. The narrator advises staying aboard during forecast bad weather or moving the boat somewhere safer, and checking that insurance covers wreck removal.

Five-minute anchoring routine

Before settling in, the video recommends:

• Checking for wind shifts and squalls.
• Considering where the boat would go if the wind reversed.
• Confirming the seabed and high-tide depth from the bow roller.
• Letting out adequate scope.
• Testing the set while watching shore landmarks.
• Attaching a snubber.
• Setting an anchor alarm.
• Planning an escape route.
