Dick Carter's Southerly 105 represents a fascinating chapter in British yacht design, combining the renowned designer's racing pedigree with the practical cruising innovations that would define the Southerly brand. Built by Northshore Shipyard from 1978 to 1984, this 35-footer established many design principles that influenced subsequent Southerly models. The defining characteristic of the Southerly 105 is its ingenious swing keel system, which transforms this capable offshore cruiser into a shallow-draft explorer. When raised, the keel dramatically reduces draft while maintaining excellent sailing performance, opening up countless anchorages and waterways typically inaccessible to conventional deep-keel yachts. This versatility makes the boat particularly appealing for coastal cruising and gunkholing. Carter's design expertise shines through in the boat's balanced proportions and seaworthy hull form. The masthead sloop rig provides straightforward sail handling, while the robust GRP construction ensures durability. With a comfort ratio of 24.16, the Southerly 105 offers a spirited sailing experience rather than a heavy, traditional cruising feel. Limited to just 105 hulls, this model has developed a devoted following among sailors who appreciate both Carter's design legacy and the practical advantages of swing keel technology for extended cruising adventures.
