Up first over the first May bank holiday is Rock in Cornwall. This is a fantastic three day event which offers the best of sailing and holidays. The racing will take place out in the Bay where there are great Waves, the occasional dolphin and the Doom Bar (pints ofthis can also be found in the bar après sailing!) Because of the tides there is also plenty of time for holidaying with great food (just ask Amy Forbes about Rick Steins!), trips on the ferry over to Padstow and if you want to keep up the water sports theme you can pop up the road to Polzeath for some of the best surf in Cornwall. There is plenty of accommodation near the club which can be booked through John Bray https://www.johnbraycornishholidays.co.uk/
This can work out pretty cheap if there is a group of you and is great for families.
