It's especially important not to leave ISS stringers locked in place during air travel. Air trapped in the polymer sleeve can expand and contract at altitude, which can potentially burst the sleeve.

What happens if I don't tighten the ISS stringer correctly? +

Not to worry, any water that enters the stringer cavity during surfing is contained within the polymer sleeve. Simply remove the stringer, clean the cavity with fresh water and allow the cavity to dry by standing the board on its tail overnight.
