Some recent S&S designs include the 60-foot Queenship Passagemaker, her big sister, the 87-foot Passagemaker from Queenship and a 151-foot custom displacement expedition vessel.

Day & Picnic Boats
With many baby boomers needing to balance busy careers, child rearing and indulging their recreational passions, a fast, open boat can provide a quick escape to the solitude of a favorite island or anchorage. S&S designs of this type can be found on all coasts. Among the firm's recent designs is the custom 45-foot fast cruising power boat PEACE and PLENTY, built by New England Boatworks.
