Protected island anchorage. Approach from the middle to avoid shoals at each tip of the island.
Simple island anchorage with good depth. The key is to approach from the middle of the island, not the ends where shoals extend. A decent stopover between Healey Falls and Hastings.
Shoals extending from either end of island — approach from the middle.
