What is the major difference between today's composite hulls made of the 1/4" fiberglass, foam material, 1/4" fiberglass construction and a full solid material like Seacast® :

  • The difference is that Seacast® is based on the same material as the rest of the boat a the hull. Seacast® has a certain amount of resiliency, which keeps it from cracking. In seventeen years we have never had a cracked or broken transom. Even with the enormous Hp hung on some transoms.
  • In contrast to foam, Seacast® is not friable - so the bond is superior. Seacast® has been tested by a dropping 20 lb weight, from a height of 10 ft, on a 6" wide 1.5” thick piece of transom - did not break after 200 repeats. In comparison, a standard plywood transom is destroyed after one drop and all other materials tested failed after the third drop.
  • As to the question of bonding to wood. Yes, it bonds very well, BUT you must remember the wood itself will be the “weak link”.
