how old is your board? sounds like maybe 8yrs + ??? if so ...yeah a new modern wave board is a must have....now all you have to decide is classic shape or the new short wide styles...you'll be AMAZED at how EASY the new stubby ones are to sail

but the new classics are great too ohhhh nooo decisions decisons,,,maybe try b4 u buy...
you might have to treat yourself and go the full hog and get new masts,sails,booms etc... aswell
my biased input go a custom SSD
