George Clooney gets in hot water with the yachting set as boats collide with newly-renovated boathouse on his £10m private Berkshire estate

After £20 million high-security renovations, Fort Clooney comes under surprise waterborne attack. The boaters were trying to turn the yacht when it got stuck by the Clooney's boathouse

George Clooney's new estate on a private island in the Thames is something of a fortress but couples out boating managed to pierce the tight security by crashing into the boathouse. As the Hollywood star and his wife Amal, a prominent human rights lawyer, welcomed their new twins into their Sonning home this week, a undignified assault on the property happened on the shore just a few yards from the house. The scene had been an idyllic one. Just the burbling of the backwater, the buzzing of dragonflies and the occasional volley of laughter echoing across the water from the Clooney estate. But calm quickly turned to panic as a large motor yacht loomed into view and attempted to turn round in the narrow straight between Clooney's island and the river bank in the sleepy Oxfordshire village.

Two elderly couples had taken this motor yacht, the Juno Too, out for a lazy afternoon cruising the backwaters of the Thames on the Berkshire-Oxfordshire borders.

The scene unfolded as they returned to moor at the Upper Thames Motor Yacht Club, opposite Clooney's island estate.

First came the sound of bickering from the launch, then squabbling, and then hollering.

Finally a loud crunch split the air as the boat ploughed headlong into Clooney's newly-built boathouse.Coming in at speed, the four soon discovered the stretch of water between Clooney's island and the moorings at the yacht club was only about 50 feet across and - importantly - made even narrower by the location of the newly-renovated boat house Clooney recently had rebuilt as part of the house renovations.
