Hi Lorna, Thank you for your message,we have loads of 17 year olds join here at the school. We run 2.5 hour lessons everyday at 10am and 2pm and we split everyone into groups of different abilities on the day. During July and August he would be guaranteed to be joined by others of a similar age. There will be lots of Mums too! If you like you can book in for the first initial lesson and then book further lessons once you are here. We are very relaxed and flexible. All the equipment is included in the price which is: £30 for one lesson £55 for two lessons £75 for three lessons £90 for four lessons £105 for five lessons All you would have to bring with you on the day is done swim wear and a towel. Hopefully hear from you soon :-) Kind regards Peter Abell Kingsurf surf school
