General for all activities
Information to help you can be found in many places
there are different rules for each sport, and even things that sound the same can be different i.e. Supervise for Dinghy sailing is very different from almost all other sports..

Key points for Adventurous activities
Where relevant a permit must be held.
Events where there are no U18s do not require permits but they are recommended.
There is no minimum or maximum age to hold a leadership or supervisory permit (except any imposed by outside agencies). There is no minimum age to hold a personal permit, but the maximum age is 17.
Recommendations for permits may be made by County assessors or external assessors in accordance with the fact sheet FS120104 Adventurous Activity Permit Scheme – Approved Assessors.
All groups undertaking adventurous activities must have immediate access to someone holding a relevant and current first aid qualification. This need not be the permit holder.
Once holding a permit an activity leader may operate with Members from another District or County (subject to the normal approval of the District/County Commissioner of the Members concerned).
Below is an example of a good form to use when organising a one off activity, we use this for our monthly trips to our local sailing club, so that everyone is clear on who is responsible for each part of the activity, from safety on the water to who will collect the buoyancy aids and tow the boats. Feel free to download it and use as you need.
