Being able to swim is certainly not a disadvantage; however, for the Discover Scuba Diving experience, there is no swimming component involved. The main focus is on you being safe and having fun. If you decide that you would like to take your diving to the next level and progress to a ‘PADI Scuba Diver’ or full ‘Open Water Diver’ course certification, there is a water fitness evaluation that includes a 200m swim and a 10-minute survival float test.
