A good estimate for pedestal permanent molds to build an open commercial work boat design is about $2000 per foot, high glass molds about 2800 per lineal ft. at 8' wide and would take about 8 months to complete. Accessorie molds such as a deck would be included. However console molds, box molds, gunne and innerliner molds may add to the price. The cost can be reduced if molds are made that copy an existing design. Design and cost studies are offered in consultation services payment options when you submit your form.
