Profile: Minderman Marine Products, Inc. produces Algonac boat hoists, boat yard carriers and propellers. We design algonac boat hoist slings, which are made of fine materials available and in a variety of widths & lengths to suit the needs of the large or small marina. Our boat yard carrier includes rapid adjusting shoring for moving craft that are not equipped with a cradle. We offer trailer dollies, which include 600 lbs. tongue weight capacity, large pneumatic tires, chrome plated ball and plastic gripped handles. Our strut bearing puller eliminates the removal of the strut from the boat or the hard pounding or sawing of the old bearing.
