 The "Toleta" is a simple table with several columns of numbers.In the first column is the angle of difference between the actual and intended courses, expressed by number of quarter-winds.Once that difference is determined, the second column gives the "Alargar" (the "Widening", the current distance the ship is from the intended course) while the third column tells the "Avanzar" (the "Advance", how much of the distance on the intended course has already been covered by sailing on the current bearing – this is equivalent of Ramon Llull's "miliaria di mari").
