Early Sea Snarks featured an unclad one-piece injection-molded EPS hull and weighed a total of approximately 30 lbs. Later versions called the Super Snark or Super Sea Snark featured a vacuum formed layer of ABS (later ASA) bonded over the EPS hull for a total weight of 50 lbs. Snark Products had patented the cladding process (which they marketed as "stronger than fiberglass") to eliminate the possibility of voids within the injection molded hull. Under Snark Products Inc., the technology was marketed as "Corelite" and is now trademarked as "Armorclad."
