Designed by Bill O’Brien and built by Reg Freeman (Yachts) Ltd in Southampton during the 1960s and 70s, the Seadog 30 is a quintessential British motor sailer that prioritizes ruggedness and safety over outright speed. With roughly 140 hulls produced, this ketch-rigged cruiser was conceived during an era when heavy-displacement hulls and protected center cockpits were the hallmarks of serious offshore voyaging. It is a vessel defined by its "go-anywhere" philosophy, often chosen by sailors who value a dry watch and the ability to punch through heavy weather. The boat’s distinctive silhouette, characterized by its high freeboard and twin-masted rig, remains a common sight in European coastal waters and among long-distance blue-water cruisers.
