Crewmembers of 12 confirmed entries in the Open Division are expected to converge for the roll call near the docks of the Subic Bay Yacht Clubs shoreline.
They will familiarize themselves with the waves, the weather and the winds of Subic Bay and in time for tomorrows opening races at 11 a.m.
Inshore races under a steady breeze running from 10 to 15 knots are expected to keep sailors on their toes throughout the four-day event sanctioned by the Philippine Sailing Association.
