............ or every ski areas that I ever visited from using one).
Probably would apply to sailing instructor pursuits .... at ski areas the use of waivers for 'volunteer' employees (instructors, ski patrollers, etc.) is usually accompanied by carefully crafted legal 'fine print' in the required waiver: (paraphrasing) the volunteer employee becomes an 'agent', not an actual employee. An 'employee', by most state corporate statutes, is protected from liability due to actual (legal) employment and is usually covered by the corporate liability policies ... by law; 'agents' can be considered as independent contractors.
In such situations (as an 'agent') the 'volunteer' (or 'agent') is or may not be protected from liability by the employer; although, the employer/contractor of 'the agent' may
have 'the agent' included in their liability coverage ... Get such in WRITING !!!!!!!
Just for a moment ask yourself: exactly why such a 'school' is requiring you to expose yourself and your boat to such potential liability?
I think when a corporate entity is demanding that you and your boat
is being used to 'teach' .... you are entering a legal limbo that may have grave consequences for your own position vs. responsibility of liability, etc. Methinks you've got to have these legal/liability issues all worked out in advance and agreed to, long before you begin.
You're going to need a lawyer and you're going to need at least supplemental personal insurance vs. potential liability, unless you have a clear WRITTEN contract that assigns all such liability responsibility to 'the school'. - IMO.
