How about:
<br>"Each boat must be equipped with a suitable righting system allowing the boat to be righted by the racing crew without outside assistance. Crews may be asked to demonstrate their ability to right their boat by the F16 HP authority if reasonable questions about the suitablility of the righting system are raised."
<br>That's "stricter" but still leaves the primary responsibility up to the "crew" while allowing "proof" if deemed necessary.
