The Coulam 152 is the latest addition to the range, not to supersede the 15 Defender, but to add a different option of layout at the stern. Instead of the buoyancy tank along the width of the transom, the 152 has a U shaped buoyancy tank / seating arrangement. This gives a good sized storage space at the stern for a fuel tank for the petrol outboard or for the Torqeedo Lithium power battery for electric motors. The additional buoyancy tank space allows for a heavier engine to be used if required. The other specification is generally the same as the Coulam 15 Defender.
