The Seal 28, designed by the prolific naval architect Angus Primrose and built by John Baker Ltd. in the late 1970s, represents a significant evolution in the British liftingkeel cruising tradition. While the smaller Seal 22 and the racingoriented Super Seal 26 often garner more historical attention, the 28 was conceived as a true coastal cruiser capable of serious passagemaking while retaining the brand's signature ability to explore shallow estuaries and drying harbors. It serves as a bridge between the trailersailer origins of the Baker yard and the larger, more substantial cruising yachts that would later define the ParkerSeal lineage.
