Sometimes you have a foamy rapid, sometimes a broad shoal, sometimes a barricade of boulders with gleams of white water springing through or leaping over its rocks. Your boat for voyaging here must be stout enough to buffet the rapid, light enough to skim the shallow, agile enough to vault over, or lithe enough to slip through, the barricade.
