I'm afraid you might be mistaken: the OED does define a waister as "Waisters, a name given to the men stationed in the waist in working the ship."
But, for 'waster':
One who lives in idleness and extravagance; one who wastefully dissipates or consumes his resources, an extravagant spender, a squanderer, spendthrift. Now chiefly dialect, with some notion of sense 6, a worthless person, ‘ne'er-do-well’.
Indeed, this usage has a long history, going right back to the 14th century. And in the 1970s, by a chemistry teacher at my school, who would frequently exclaim "You're a waster, boy!" to miscreants.
