My child isn’t a good swimmer. Is it safe to go to the sea and the pool?

At camp we offer swimming classes every day. Experienced coaches teach children in the pools and there’s always supervision by lifeguards and appropriate aids (e.g. boards, inflatable arm bands etc.). Despite this it is good to keep the camp informed. Daily swims in the sea and water games are all done in a supervised space and under the supervision of staff members (lifeguards, counselors, group leaders).
