The Challenger 31 is a relatively unknown design from the board of Angus Primrose and built by the highly respected Trident Marine. Moody like in her appearance the Challenger 31 shares the flared bow, knuckled hull at the sheer and fuller hull sections found in the Primrose designed Moodys of the era. A solid and reliable cruiser she offers her crew spacious accommodation below decks with a well protected cockpit aft.
