Griff Rhys Jones has launched a new lifeboat in West Mersea in Essex.
The lifeboat is named 'Just George' after George Stribling from Weeley in Essex who donated £125,000 to build it.
The remaining £89,000 was fundraised locally.
It has a new navigation system radar and a sophisticated chart plotter to help locate those in distress
A heatwave is forecast next week and with it comes a warning that the weather can be unpredictable.
Martin Wade, Lifeboat Operations Manager, said: "We will have people going out in a boat with a t-shirt and shorts in the morning but come later in the afternoon the weather can change and a storm can come through, their engine breaks down and all of a sudden they are in trouble. it is being prepared and having enough clothing on board."
