STL replaces the previously named SPL - Spinnaker Pole Length.


A measurement must be supplied for any spinnaker pole, whisker pole, bowsprit, or the distance to the spinnaker tack point on the deck, whichever is the greatest.  Please read the full definition.


Errata: On the drawing on page 43 of the IRC 2002 yearbook, "SPL" should read "STL".
