Six people needed rescuing from near Bordeaux after their boat got stuck on rocks just outside the harbour on Saturday morning.
Someone on board another boat called the Coastguard for help just after half past eight.
The people on board the stuck boat needed immediate help with the St Peter Port Inshore Lifeboat (pictured top) getting there by 09:00 to bring them ashore.
There were no reported injuries but the boat itself was at risk of severe damage.
A spokesperson for Guernsey Coastguard said it was likely to shift on the rocks as the tide fell, with the Sarnia Workboat also sent out to help re-float it.
As the tide receded, a tow line was established and the boat was pulled from the rocks, and towed into St Sampson Harbour.
Duty SAR Mission Coordinator (SMC) Simon Granger said the situation could have been much worse if it hadn’t been for the help of the people onboard the passing vessel.
“This was a successful outcome with no injuries, I would like to thank the reporting vessel who called the Coastguard in a timely manner and then remained on scene keeping a watch on the casualty until the lifeboat arrived. I would also like to thank the crews of the St Peter Port Lifeboat, and the team onboard the Sarnia workboat for their swift, professional, and coordinated response”
