We keep our 2008 Hunter 33 in the Severn River, Maryland. We pull it every other year. When our marina pulled the boat in Nov 2017 they contacted us to say that half of our rudder fell off. What happed is one side delaminated and fell off. We have an estimate to replace of $4200. Progressive insurance would not cover it. It could happen again. Does anyone know of insurance that would cover this problem?
