just a thought does anyone think I could install a mast track in an old 210 liter naish mana??? JUSt learning to wind surf and brought an old windrush ,2 sails ,booms and masts for $150 on gumtree .Sick of summer howling nor easters Getting the hang of it for an old fella, want to faster,but wife won't let me get a new board,don't know why,what's wrong with 5 sups,a mal,a shortboard. mats and various other watercraft. Ive seen some of the guys lurk on both Sup and windsurf sites,thought maybe some of you might have an answer. cheers
