Grays Harbor Historical Seaport's volunteer sail training program Two Weeks Before the Mast (TWBM) is a 14-day crash course on life aboard a working tall ship. TSC's Recreational Marlinspike course is the prerequisite to TWBM, and is a week long online program for the recreational mariner to learn the basics of tall ship sailing before joining a vessel.  


Students will be enrolled in our Recreational Marlinspike course once they have been accepted into Two Weeks Before the Mast. Recreational Marlinspike is not a stand alone course outside of TWBM.
