Although today was due to be mostly cloudy, tomorrow and Monday were expected to be mainly sunny with temperatures climbing to 20°C.
The event, which opens at 10 am today and finishes on Monday evening, features a range of boats and yachts from premium manufacturers. Royal Navy vessels, including the offshore patrol ship HMS Mersey, will also be on display and a Royal Navy Lynx helicopter will be stationed on the grass above the Waterfront car park.
Meanwhile, a charity that aims to get disabled and disadvantaged Islanders out on to the sea has raised enough money to buy its first specially-adapted powerboat.
Wetwheels was launched last year and in just a few months has raised £140,000 to buy the 40-knot powerboat, which is currently under construction in the UK.
Supporters of the charity include former UK Yachtsman of the Year, disabled mariner Geoff Holt, who will be officially opening the Boat Show and who has brought his own Wetwheels craft to the Island for the show.
