I just called the dealer . And asked that question. the response is this
this boat is for ocean use only. Or as the guy said. they made it to go
in the ocean only. it is to large for rivers and lakes. so they are only
putting a 5 year warrenty on the hull. I am sure it's the stresses that
the ocean puts on the hull. and corrosion.
They bought the hull design for the O/S from Almar and they only had the 5 year warranty on theirs. So North River left the warranty on the hull design the same. This is according to someone at the North River plant.
