3. Navigating the Scraper
If you look out towards Cape St. Albans you can see a rough-looking line where the water breaks over the shallows of Scraper Shoal. If there’s a reasonable swell you’ll see big breakers rolling in. The American schooner the Kona was wrecked on the Scraper on a particularly low tide in January 1917. The water depth over the shoal on a low tide is about two metres.
Imagine witnessing, only a few years later in September 1923, the sails of the Garthneill, a large square-rigged barque, in the same waters. Her Captain reported: ‘We sailed through the passage between the Scraper (sic) and Cape St. Albans without a particle of danger.... The channel was about a quarter of a mile wide and we were running before the wind with top sails and top gallant sails set.’ It was at the time ‘hailed as a wonderful feat of navigation for a sailing ship master’.
