I don't know your coach, but attached is a link to a PDF manual for 2012 Hurricane/Windsport. Check under water systems page 87. I think if your 2011 is the same as 2012 they say the low point drains for Windsport are the exterior shower in an outside compartment. Maybe someone else with more knowledge of this year/coach will chime in.
